New Features in VideoFOCUS Pro 10.0

The advances in VideoFOCUS 10 continue to be towards performance. Building on our use of the GPU to improve processing operations in version 9, in version 10 we have turned our attention to a major re-write of the screen capture capability, including the use of the GPU to provide 4K capture support and to offer a much more efficient UI experience.

Quick Capture

Although we strive to provide direct import for as many media types as possible, there are often circumstances where viewing the video in the DVR vendor player is the only option, or where the relevant video is hosted online and embedded web players with no download capabilities are the only option for viewing. Screen capture is the solution in these situations, but like all video, video from these sources is following the trend towards ever increasing frame size and ever increasing frame rate. As these trends continue a screen capture that is to meet the challenge must be designed with the highest performing approaches, and to handle the most demanding circumstances it must leverage the capabilities in the GPU. We have created the new VideoFOCUS 10 Quick Capture with exactly this in mind so our users will continue to have an option for all the video they encounter in the future even when there is no possibility of direct import.

Additionally, much about the workstation graphics environment has changed since the original VideoFOCUS screen capture was released. Multiple monitors with high DPI displays and screen scaling are commonplace, and users wish flexibility with respect to where tasks are run and interaction is performed. With this in mind Quick Capture has been designed to provide a very direct and efficient process for video selection from any source on any screen, and offer simple interaction as needed to do the precise selections often desired when capturing video for forensic purposes.

Feature Summary

Operation

Quick Capture can be launched from the toolbar, the file menu or using the F2 key. We believe that it will supersede the older capture in all cases, but the original screen capture is retained for the time being and is accessible via the F3 key and the file menu.

Source Selection

The selector panel provides interaction for capture source selection. When source selection is active a green border appears around each monitor in the system and interaction with windows other than the capture dialog is disabled. The selector modes are explained below.
Manual

Activates manual mode. The selected area of the screen is identified by a orange dotted line. Adjustments to the position can be made using the mouse, or via the fields in the capture panel. Mouse interaction includes drag and drop to define the area, and drag of the selection edges and corners to refine the area. When near an edge or corner the mouse wheel can be used for fine scale adjustment.

Automatic
When in automatic mode OS application and child windows are automatically highlighted in red as the cursor moves near them. A mouse click will select the highlighted area and the selector will move to manual mode. Modern OS window edge decoration means automatic selection boundaries may not be exactly as desired, but a transition to Manual mode allows for fine scale adjustments to be applied. If a window is partially obscured a additional click is first required to bring the window to the front.
Additional menu offering selection of full desktop of each display.
Hide
Disables the selector, leaving the last selected area as the target area for capture. This mode can be used if window rearrangement is required, optionally returning to manual or automatic mode to complete the selection.

Selection Display

During selection the selected area is displayed in the capture dialog, either in its entirety, or when the mouse is close to the boundary in a magnified view. The magnified view allows for pixel precise selection of the edges of the capture area. While in magnified view the thin solid line displays the precise boundary of the selection.

The selection display also includes a informational banner presenting information on the selected display source. This information is important in the following ways.

Monitor Refresh Rate
The mechanism used to access the display data provides the highest performance available but even so the maximum rate of access to the video is the refresh rate of the monitor. For the majority of video sources the monitor refresh rate is sufficient to handle the frame rate of video, but when the video rate approaches or exceeds the monitor refresh rate this information can be used to decide whether a capture will be successful, or a reconfiguration of display mode and refresh rate might be required.
Monitor Scaling
Quick Capture will always capture at the underlying resolution of the display, as this is the avoids any scaling of the captured video frames, but depending on the player, when capturing on an OS scaled screen the results can be unexpected. Older player's that are not DPI aware may not take into account that the OS will scale all their graphics, including video frame images. As a result, even when an 'actual size' display mode is selected in the player the captured video may be scaled by the OS and the dimensions of the video area may not match expectation. Selecting a display with, or reconfiguring a display to, 100% scaling may be desirable for such players.

Coordinate Control

The coordinate control provides a continuous presentation of the pixel location and size of the area selected for capture. It also provides an alternative way to establish and adjust screen selections in terms of position and width and height. The fixed checkbox controls whether mouse interaction with the selection area on the screen adjusts the size of the selection area. When fixed is selected the manual mode mouse adjustments only move the selection area. This allows for situations where the capture size is known and the user is attempting to determine whether a player is presenting the video at that size and align that capture area to the correct region of the player window.

Encoding Options

The encoding options provide for both uncompressed and compressed video capture and the optional inclusion of audio. When audio is checked the capture system will also record what is known as the 'loopback' or 'what you hear' audio stream available from the currently selected audio output device.

Encoding options can be changed at any time when not capturing and changes to encoding will not adjust the current capture selection.

MP4 Compressed
H264 encoded video and AAC encoded audio in an MP4. This option is generally the best choice for any capture that is substantial in terms of duration, frame rate or frame dimensions. We have engineered this capture to make use of GPU based hardware encoding when available, so it offers the best possibility of no drop capture in most circumstances, and is a necessary choice in conjunction with a suitable GPU when attempting to capture UHD sized video at typical production video frame rates.
Uncompressed
Raw 32bit RGB video and PCM audio in an MOV. Unfortunately GPU assistance is not meaningfully helpful for uncompressed video (or any compression that is lossless) because data rates are in many circumstances too high so the uncompressed option is only applicable for modest frame rates or modest dimensioned video that must be captured in a lossless format. Maximum no drop frame rates are a function of frame size and data rates are substantial.

The label field allows for pre-definition of the label for the captured session and dictates the name of the captured media file in the case. The label name can be changed to any meaningful name and will subsequently auto advance with each capture.

Capture Actions

The capture actions provide the typical start stop interaction plus the ability to temporarily pause the capture and to snapshot the capture selection wile capturing or at any other time.
Snap
Creates a still image of the current capture selection area. This can be used to quickly capture images from any static or video source on the display.
Start (Stop)
Start capture with the current selection and audio choice.
Pause (Resume)
Temporarily pause the ongoing capture. Pause is not available when also capturing audio.
Cancel
Stop the capture without saving the result.

Capture Performance Information

Rate
The rate of frame update while capturing (average over the last 10 seconds). This provides an indication that can be used to determine the frame rate of video and whether that rate might be close to the monitor refresh rate and therefore creating a risk of exceeding maximum capture rate.
Frames
Provides a count of the total number of frames captured.
Drops
Provides a count of the number of frames where the windows system has indicated more than one display update occurred between the current and previous captured frame. Missed updates a.k.a 'drops' typically occur because the system cannot transfer and encode the frames from the display or store the frames to the disk fast enough.

Quick Capture records the timing of any drops and adds a labeling to the captured session that can be used as an aid in determining whether a potential drop is significant to the integrity of the capture video. These labels can be selected and reviewed by the section advance capabilities of the VideoFOCUS player.

The label is attached to the frame that immediately follows the point in time where the 'drop' was indicated. Ideally it would be a line between this and the prior frame, but we currently don't have the ability to indicate in that way.

Performance

Important points to keep in mind.

Computers with faster processors are less likely to drop frames and players are less likely to skip frames on such machines. Computers with higher end GPU's are less likely to drop frames especially for larger frame sizes.

Limitations

In this release pausing is not available when capturing audio is enabled as frame timing problems will occur in the captured result.

In this release loopback audio devices that work at sample rates other than 48000Hz or 44100Hz cannot be used for MP4 capture.

Drops are calculated from the system's information about the changed screen areas and erroneous drop indications can be generated if areas of the screen other than the capture area update multiple times during the time of a single update of the capture area.

Quick Capture is only supported on Windows 10 and GPU acceleration is dictated by the DirectX capabilities of the GPU.

Due to graphics limitations, area selection on OS scaled screens may show a slightly displaced dashed highlight in the magnified view, but the precise boundary line can still be relied upon to display the actual pixel level selection boundary.

Other Improvements

Sort Options for Session List

In an attempt to try to make the challenge of working with many sessions in a case somewhat simpler we have introduced the ability to sort the sessions in different ways.

Relationship
A sort that attempts to keep closely related items next to each other in an ancestor like order.
Item Type
A sort that groups items in the following order: demos, imports, captures, modification and processing, and exports.
Created Time
A sort that orders items according to the time that they were created by the user.

Audio Capture

We have introduced a simple audio only capture facility. The control is opened from the file menu and provides for the capture of the 'what you hear' mix from the sound card. Currently the audio capture supports the uncompressed WAV format.

Floating Point Audio Capture

When audio is captured in an uncompressed format, either as an audio track in an MOV or in a WAV file, the settings allow for the choice of 32 bit floating point audio instead of the default 16 bit signed PCM format.

Floating Point Audio Import

The media audio track decode has been upgraded to directly produce 32 bit floating point audio so that original media containing high precision audio tracks (e.g. 24 bit integer or floating point) can be imported and processed without any precision loss.

Features Introduced in Previous Versions

Introduced in VideoFOCUS Pro 9.0

The focus of version 9.0 is performance. We have upgraded the media handling architecture to support interactive performance for the larger media frame sizes that are now encountered in surveillance video. In addition to using GPU resources to accelerate filtering, in systems with a suitable NVidia GPU VideoFOCUS will use the GPU to accelerate h264 and hevc decode and encode, providing for a better general processing and export experience especially on larger frame size video.

Media Handling for High Resolution Video

An updated media architecture in Version 9 enables the possibility of interactive processing of high resolution video on a reasonable spec contemporary computer system. By automatically working with scaled versions of the video media right up to the point of the final export render the computing resource requirements when interactively processing high resolution video are substantially lower and hence interactive performance is improved. This behavior is automatic and requires no action on the part of the user.

Accelerated Media Reading

To compliment the improved architecture Version 9 can now make use of suitable NVIDIA GPU resources to perform h264 and hevc decoding. With the vast majority of security and surveillance video encoded using these codecs this offers a substantial advantage for a large portion of the video encountered by freeing the CPU to perform the processing tasks.

At this time we are unable to automatically determine the capacity of the GPU to process multiple streams so we offer a control in the Edit->Preferences to limit the number of simultaneous GPU decodes. Generally speaking 4 or 6 is sufficient for most situations but if the GPU has limited memory it may be necessary to lower the count to 2 or perhaps even 0 if other problems occur. VideoFOCUS will automatically fall back to processor based decoding when the limits are reached.

Export as Two Steps

We were concerned that the existing VideoFOCUS export process does not make it easy to properly review the export product and fully leverage the value of VideoFOCUS's automatic report generation.

To address this we have split the export into two steps. The first step is the generation of the export media item and the second step is the copy of the export item to an external location. As such the export dialog now contains a "Render" and a "Export" option as a drop down button in the export dialog. The render option renders a version of the selected audio, video or images with the chosen formats etc, and adds those items to the VideoFOCUS case as part of the processing chain. This allows the user the opportunity to review the rendered media with actions like 'open in system' prior to saving them to an external location. It also allows for report notes to be added to the export item and the option to refine the report prior to a final save without the need to re-render the media.

For those who are satisfied with the existing export experience the export option provides a one step action very similar to previous export experience. The only difference being that the rendered items are also added to the case but that action can be disabled by deselecting the checkbox option in the export dialog.

Accelerated Media Export

Version 9 can now also make use of suitable NVIDIA GPU resources to perform h264 and hevc encoding. This option is on by default when producing MP4 but can be disabled on a case by case basis using the checkbox in the export dialog.

Notes on Encoding Quality

It may be necessary to fall back on software encoding for systems where instability or quality issues are observed when using the hardware encoding option. This can be achieved in export by deselecting the use GPU option and in capture by deselecting the hardware capture encoding option in the Edit->Preferences dialog.

By default H264 encoding now uses the "Main" profile. If quality issues are observed in the MP4 then the Edit->Preferences panel offers a checkbox to revert to using the "Baseline" profile of previous versions. This setting affects the encoding for both MP4/H264 capture and MP4/H264 export.

Capture Pause

We have introduced a pause capability in the screen capture to support the creation of single capture files that include non time contiguous sections of video.

The preferences dialog allows the user to control how the pause period is represented in the capture file. The preferences allows specification of the number of black frames that are inserted (between zero and 100) and the duration of each frame (expressed as a frame rate)

One possible use of pause is to append multiple DVR player time segments that are in different source files into one single capture file. Note however that if the capture target is selected in VF as a specific player window (via source selection) then that window cannot close between sections separated by a pause since that would cause VF to lose track of the source window.

Also note that in the current version the subsequent time setting or addition of a timestamp in the video is not likely to be meaningful for the whole video because of the non contiguous nature of the underlying real world time of each segment

Other Improvements

Player Controls

Version 9 offers interactive controls to position the player to a specific frame or a specific relative or absolute time. The controls are spinners and in the case of the time controls parts of the value fields can be selected to allow for advance by seconds,minutes, hours etc using the spinner buttons.

Tracking

We are planning to revisit our filter tracking in a future release but for Version 9 we have adjusted the tracking to prevent distortion of the track region when the track location is being computed. We believe this will improved the tracking experience.

Introduced in VideoFOCUS Pro 8.1

MP4 Screen Capture

VideoFOCUS offers proprietary DVR media import however in some cases when a media file is unsupported the user typically resorts to the VideoFOCUS integrated screen capture. Prior to this VideoFOCUS version, screen capture has recorded the captured player as uncompressed video and audio. Now, because of the advent of HD cameras it is increasingly common for DVRs to record video at HD or larger frame sizes and it can be impractical to screen capture this into an uncompressed format due to the overwhelming storage requirements for large frame size uncompressed video.

To address this problem this version of VideoFOCUS introduces the option for MP4 compressed capture. The choice between uncompressed and MP4 can be selected directly in the capture dialog and can be changed between captures when capture is stopped.

Impact on Quality

The MP4 is encoded as H264 video and AAC audio with bit rates that correspond to typical high quality MP4 encoding. Although not lossless, for the vast majority of DVR media any adverse impact on quality or perceptibility of events in the original scene is associated with the original DVR recording processes (compression, frame rate reduction etc) rather than the additional MP4 encoding associated with the screen capture activity.

Impact on Performance

Although H264 encoding does require more contribution from the CPU, the benefits of the much reduced rate of data (~50-100 times less than uncompressed) act to compensate, with the net result that on contemporary machines overall performance appears to be improved in most situations. Furthermore, at the largest DVR media frame dimensions, compressed screen capture is the only practical solution due to the overwhelming rate of data that would be associated with an uncompressed recording.

Media Save

VideoFOCUS stores captured and imported media data in a simple directory based data store. A number of customers make direct use of the data within this store as part of their workflow. Often they do this to avoid the time associated with an extra export operation when wishing to make use of media files externally that have had no processing beyond only capture or import.

Although it is practical to access the store directly, officially the store is under the management of the VideoFOCUS application, and therefore there is always a need to keep in mind the possibility of unexpected file naming, and automatic file additions and deletions. There is also the risk that a user performing an inadvertent move instead of copy of a file from the store will leave the store in an invalid state.

To better support these users, this version of VideoFOCUS introduces a direct media save action. The action is available on sessions that have associated media, so typically captured and imported sessions. The save action is performed by a copy at the OS level and is effectively instantaneous for most normal duration MP4 screen capture files and imported media files.

Other Changes

Updated Frame View Selection

In prior versions of VideoFOCUS any mouse interaction with the frame view (e.g. clicking on a frame or a right click mouse action) would typically lead to the loss of the current frame selection, which can be undesired, especially if the selection is a complicated multi-select and difficult to construct. In this version of VideoFOCUS changes in the frame selection in the frame view when clicking with the mouse happen only when the shift or control key is selected. The behavior of the shift and control key is designed to be as close as possible to that experienced in the player view and consistent with normal text editor selection conventions associated with these keys.

Current Frame Labeling

To avoid confusion when labeling individual frames if a selection is present, the right click popup introduces the new menu action "Label Current Frame". This action offers the same options as "Label Selected Frames" but acts only on the focused frame. In the player view the focused frame is the visible frame, and in the frames view it is the one identified by the dashed border.

Old Version Recovery

When a project is opened by a newer version of VideoFOCUS than the VideoFOCUS version that last saved the project, the project file is copied to a backup and recovery instructions are included in the project folder. (note recovery is only generally possible if no media items have been deleted using the newer VideoFOCUS version). In conjunction with this change the naming of the project data file in the project store now offers a more direct indication of the VideoFOCUS version used in its creation.

Safe Mode Start

If the F8 key is pressed when starting VideoFOCUS, the user will be offered the option of starting without opening any projects. This can be used to avoid problems in a specific previously open project that prevent the proper startup of VideoFOCUS.

Introduced in VideoFOCUS Pro 8.0

Timestamp

VideoFOCUS 8.0 supports the ability to place a clock like timestamp in any video or image. The timestamp will display the value of the absolute time of the displayed frame or image. The timestamp can be positioned with user determined sizing and location and can be relocated to a new position at any point during the video. The colors of the timestamp lettering and background are user defined, and a transparent background is supported.

The timestamp will take account of any subsequent time management operations in VideoFOCUS (via adjust time or manage views) and will maintain correct frame time in an edited video where sections are been removed or even if different videos have been introduced. The timestamp is not rendered into the video (unless a multivideo edit or export is performed) so can generally be removed at any later point in processing if it is not required or has to be changed.

Timestamps are added via the Annotation dialog accessed via the annotation menu item in the edit menu, or the session or still popup menu.

Annotations

VideoFOCUS now provides support for the identification and labeling of spatial regions in video and images. Like timestamps these annotations are positioned with user determined sizing and location, and can be relocated as needed. In addition the annotations can be placed in a tracking mode which causes VideoFOCUS to attempt to follow the object in the image as the object or the camera moves. As with tracking in the filter dialog, manual intervention to correct size an location is supported. The colors of the shape and label lettering and background are user controlled and the shape can be hidden to leave only the label.

Annotations are not rendered into the image until export (or multivideo edit), so spatial operations (e.g resizing, rotation, cropping) on the video will preserve the legibility of the labels. Like timestamps, annotations can be removed even after subsequent processing steps have been performed.

Label annotations are added via the Annotation dialog accessed via the annotation menu item in the edit menu, or the session or still popup menu.

Copy and Set Time

To aid in the process of establishing the proper time relationship between related videos we have introduced the concept of copying time from a video and and setting time in a videos.

In the context of synchronizing multi-view video in the ManageViews dialog this feature allows the user to scrub one view to a specific event, and right-click copy time, then click on another view also containing the event, scrub until the event is visible and then right-click set the time. Doing so will adjust the time of the second view such that the event now occurs at the same time in both views. This can be repeated for further views that are to be brought into time sync.

A similar procedure can be used in conjuction with the Adjust Time dialog for single videos. In this case the event would be located in the main player of the first video and followed by a right-click copy action. Among other things this will copy the current time into the clipboard. Then the second video can be opened in the Adjust Time dialog, the same event located in the second video, and finally the right-click set time performed. Doing so will adjust the time of the second video such that the event now occurs at the same time in both videos. This can repeated for further videos that are to be brought into a common time sync.

Other Changes

High DPI Displays

The majority of VideoFOCUS is now DPI aware, which means that the interface and text should no longer appear unduly small on screens that are high DPI (small and medium sized monitors with a high resolution). No user action is required, and dialogs and windows will be sized appropriately depending upon the specifics of the monitor on which they appear.

Unfortunately due to limitations in the Windows OS support for high DPI, we cannot currently offer DPI aware behavior for the parts of the windows associated with the Minilab and QuickEnhance audio interface. This means these parts of the filter interfaces will continue to appear smaller than desirable. This situation may change as Microsoft improves developer support for high DPI

Doc and Html Report Formats

In addition to pdf, exported reports are now available in html and a doc format that can be opened in Microsoft Word. The choice of format is made via a dropdown in the export dialog.

Improved Case Compatability Information

As part of advancing VideoFOCUS functionality it is often necessary to make changes to the data format for cases. Sometimes VideoFOCUS improvements add additional items to the data, which means that cases created with a new VideoFOCUS cannot be opened with older VideoFOCUS's and occasionaly VideoFOCUS improvements make changes to existing items in the data, which means that the new VideoFOCUS cannot open older cases.

In order to make this as easy as possible to manage for the user we have updated the behavior of the open case dialog. Firstly the open case file browser provides further visual hints as to the situation. It does so by coloring cases with a red icon if they can be opened by the version of videofocus being run or by a grey icon if they cannot. In either situation it annotates the case file name in the file view with the version of videofocus that last opened the case. Furthermore if an attempt to open a grey case is made VideoFOCUS will inform the user which version of VideoFOCUS is required to open the case.

Older versions of VideoFOCUS are available from our website and can be installed alongside newer versions to support simple access to older case work.

Introduced in VFPro 7.0

Reporting

VideoFOCUS 7.0 can now generate pdf report documents describing video and image items in a project.

A report can be created by selecting the desired media items and choosing the 'view report' item in the view menu. Alternatively individual image or video items can be reported on by using the 'view report' menu action from the session or still list popup menus. A report can also be created by selecting the option in the export media dialog. In this situation a report will be created that includes sections for each media item that is being exported.

VideoFOCUS will automatically generate a full 'steps to reproduce' section for each item in the report and will provide a basic summary of the properties of each item that is being reported. In addition to the automatically generated sections the user can also add item specific notes to each media item using the session or still property dialog and these notes will be included in the report. The VideoFOCUS cases now offer properties than can be set, including agency and examiner names, case number and title and an overall notes section and these properties will also be used in the composition of the report.

Macros

VideoFOCUS now supports the concept of macros. Macros are a way to apply a set of actions taken on one piece of media to other similar media, without having to repeat the actions in the user interface. Typically this might be used to apply similar processing to related videos that are determined to require the same sequence of modifications,filtering etc in every case.

There is no specific process to define the steps in a macro. All that is required is to select an item that is the product of processing and use the right click menu 'copy macro starting at'. When this is menu option is selected VideoFOCUS will offer the various points in the processing history of the item as starting point for the macro action. The macro processing include all steps between that point and an the final step producing the selected media item

Once copied the macro can be applied to other items by simply selecting them and using the 'apply macro' popup action. When applied the macro application will produce a new item that are the macro steps applied to that item. It is also possible to apply a macro to a set of selected items as a single action. In his case a result will be created for each selected item.

Macro actions are full described in the report in terms of the original actions that compose the steps of the macro and then application of the macro. Macros of macros are also supported.

Under certain circumstances the application of a macro can lead to invalid output. Most commonly this will be when references are made to times or views that do not exist in the target media. VideoFOCUS is designed to detect such situations and will advise the user that the macro cannot be applied.

Unified Export

VideoFOCUS now has a single export dialog that supports the simultaneous export of images, video and audio. The items that are export depends on which export menu is used and what is selected. When the export is invoked from the session list popup the export is restricted to selected items in that list. Similarly when the export is invoked from the stills area popup the export is limited to selected items in that list.

If however the export is invoked from the main file menu the export will included all selected items in both the session and stills areas. When combined with the report option, this allows for a production of a single report including all items that a user may wish to export from VideoFOCUS. When there is a mixed set of media types in the export dialog the video, images and audio tabs provide for control over any configurable aspects of each specific type.

Other Changes

Item Labeling and Tooltips

VideoFOCUS has been updated to provide a more consistent methodology for the labeling of media items created by filters, modification, edits etc. There is now also a tooltip associated with each media item offering a short description of the process step that was used to create the item. The tooltip includes the label name of the item's source to aid in locating the source item

Project Time Zone

Projects can now use timezone that is distinct from the system or default VideoFOCUS time zone. The time zone choice is available via the File menu item 'project properties'. The timezone choice controls the presentation of times in both the interface and in and reports associated with items in the project

Introduced in VFPro 6.1

Labels

VideoFOCUS 6.1 extends the concept of marked frames into a fully flexible way to label moments and intervals of time in any video.

Labels can be added to individual frames or selected regions of time in a video via a popup menu command. The label can be chosen from the existing labels or new labels can be created. Labels can be cycled on and off by repeated application of the label action. Labels are case wide so can be used to identify the appearance of related items in different videos within the same case. Labels propagate through processing operations and will appear at the correct time even if the processing changes the timing of the videos.

Labeled moments and intervals are visualized by "badges" that have the label name and color and are shown in the video at the appropriate time as the player plays the video. Labels present in a video also appear as a choice in the frames view in the "thumbnail display" drop-down. Choosing a label in the drop down will result in only the frames containing that label being displayed.

When labeled times are present in a case the popup menu action "Select all items labeled" will select all video items that contain the chosen label. If labeled times are present in a given video the popup menu action "Select all times labeled" will select all the times that a given label are present in the video. This selection can then be used to perform additional actions.

There are two new selection back and forward buttons in the player which when combined with the "select all times labeled" action make it simple to jump forward and backwards in a video through all the time intervals defined by a given label.

Labels can be managed project wide via the "Edit labels" action on the main menu bar. The dialog that appears allows the labels to renamed, colors to be changed or labels deleted. Changes or deletions will apply across all labeled times within all items in the case.

Key Frame

When the information is available VideoFocus will detect and display a "key frame" label identifying the frames that the video reader has identified as key frames (I frames). This label is shown in the player and also available in the "thumbnail display" drop-down and can be used to view all the key frames in a video.

Audio Redaction

VideoFOCUS now supports one click audio redaction. Any multi-video or video with audio or audio only media can be redacted. redaction is performed by selecting the time region(s) to be redacted and using the "redact audio" menu item. The menu offers the choice to either substitute tone or silence in the areas where the redaction is to be applied.

If there are many regions to be redacted labels can be useful. The first step is to label all the time regions with a label. Then use the "select all times containing" to select all the times containing the label, then apply the redaction operation.

View Management

VideoFOCUS 6.0 introduced multi-view video management with a basic timing adjustment tool to allow for the timing between views to be adjusted. VideoFOCUS 6.1 builds on this tool with an updated version accessible via the "view management" menu item. View Management is time zone region aware and allows for individual view timings to be specified in the time zone region of the user's choosing. The time adjustment control has also been updated to make for simpler timing adjustment.

View management now includes a view order control which allows the view order to be changed allowing for better visualization of multiple views where there is a natural left/right or top bottom order or for other circumstances where a change in order is appropriate. Individual views or sets of views can be shifted in either direction relative to their unselected neighbors.

As with the video viewer, individual views are selected by clicking on them, and additional views can be added to the selection by holding down control while clicking. Control A will select all the views of a multi-video.

Compact Video Listing

We have significantly revised the video list view to make for easier understanding of the origins and relationships between video in a case.

Items that represent the original capture or import are identified by a small disk drive icon. This indicates that they represent the original contents of a media file or proprietary DVR file. Items identified this way will have additional properties in their property panel describing details of the file such as size, hash codes etc.

Items in the list that represent the result of processing will have one or more arrows above them indicating the source of the item. If the item immediately above is the source then there will be an arrow in the center. If another item higher in the list is the source then there will be an arrow on the left. If both the immediately above and an other are sources then both arrows will show. In the case where the item has more than two sources a third arrow will appear on the right.

Video Visualization

The visualization of video in the player has been changed to provide a better interaction experience for image zoom and time zoom.

Image Zoom and Pan

Each camera view in a multi-view video now has its own zoom and pan using mouse drag for pan, mouse wheel roll and control +/- keys for zoom.

Time Zoom

The zoom controlling the extent and therefore sensitivity of the primary time slider has been made logarithmic to provide for better precision in selecting an appropriately zoomed timescale for the task at hand. The behavior when sliding the overview slider (the lower slider that becomes active when the time is zoomed) has also been refined so that there is a smooth centering of the primary slider when the overview position is moved. We believe these changes will help the user who is working with the longer videos produced from view combinations that may contain 10's of thousands of frames.

Tracking

Tracking within the filters, in particular to apply a blur or highlight, has been a popular capability but the interaction required to define tracks has been somewhat involved. In particular the interface has required that the region be redrawn entirely if the track goes astray and the region can become significantly distorted even if it does not depart from its intended target. A further complication involved the need to specifically select or deselect tracks for correction.

This update resolves all of these problems. Tracks that have departed from the intended target can simply be dragged back onto the target. Distortion is now much less likely as the region will retain its general shape, however if adjustment is required the regions can be resized by moving to their edge to display the appropriate resize cursor and dragging the edge or corner back to its proper location. There is also no need to explicitly select a shape as that happens automatically if a move or resize is performed, but the option to do so is there by simply clicking near the shape.

In addition, when a track has been moved or resized by the user the action can be undone by the newly added anchor control button.

File Hashes

All items that are associated with a file now have hashes automatically computed and displayed (MD5,SHA-1,SHA-256). For imported or captured items the hashes can be viewed in the item's property panel. For exports the hash is automatically computed and available in the export audit. The audit now also includes the hashes of all imported or captured items that were used as source material for the item being exported.

Multi-view Edit and Export Layout

When editing or exporting multi-view video from VideoFOCUS all views are rendered into a single composite view before the edit or export occurs. By default the views are placed on a grid with row and column counts chosen so that the result most closely matches the 'average' aspect of the individual views. Users can now override this default and lay out the camera views in any grid shape they choose, ranging from all in a row to all in a column. This combined with the view ordering operation in view management allows for nearly complete flexibility in how multi-view video looks when exported as a single playable video.

Other Improvements

Audio Edit

The editor can now be used to edit audio only items in the same way as video items.

Super-resolution

Super-resolution now provides a player in the left hand view to better assist in the optimal choice of frame for a super-resolution attempt.

Time Zone region

The application's time zone region choice is taken into account in all places where time is displayed.

Extract Views

Multi-view items offer an extract views that will create single camera view for all the selected views in the multi-view.

Introduced in VFPro 6.0

MultiView support

VideoFOCUS 6.0 provides a major advance in productivity for work with multiple camera views in the form of MultiView sessions.

MultiView sessions keep related views together with absolute timing allowing the user to establish a time coherent view of incidents captured by mutiple cameras from any source. Multi camera DVR imports now automatically create MultiView sessions but they can be also created at any time in VFPro 6.0 by combining existing video sessions or adding new video to an existing MultiView session

MultiView sessions can be viewed and operated on in the primary video player just like regular sessions, and individual views can be 'popped out' in the player to provide for detailed examination of the video and the frames just as can be done with regular sessions. Individual views in a MultiView session can be selected, copied and pasted into the session list as individual sessions. Subsets of the views can also be selected, copied and pasted to produce new MultiView sessions.

Combine Operation and Track Timing Dialog

The track timing dialog provides the user with an efficient way to combine video from different views or from different times of the same view into a coherent easy to visualize MultiView session. The track timing feature can also be used to make timing changes to any view in an existing MultiView session.

MultiView Processing and Modify

Where appropriate VFPro 6.0 supports video processing of all or a selected subset of views of a MultiView session. Modification of individual selected views of a MultiView session is also supported. In all cases the results are produced in a new MultiView session with the processing and modifications applied to the selected views.

Known Issues in VFPro 6.0

Issues that have been discovered, but not yet addressed are listed below:

Introduced in VFPro 5.1

VFPro Is Now 64-bit

VideoFOCUS 5.1 is now 64-bit, and will only work with a 64-bit OS. The 64-bit version will allow VideoFOCUS to utilize more of your computer's memory and improve performance within the application. This will especially help with larger HD (High Definition) videos.

VFPro Direct DVR import

VideoFOCUS 5.1 will now directly import many DVR formats, allowing you to import proprietary DVR formats into VideoFOCUS quickly without having to screen capture or convert the videos.

Frame Averaging

VFPro 6.0 adds support for video frame averaging to the super resolution processing filter.

Introduced in VFPro 5.0

CARDINAL MiniLab Audio Suite

VideoFOCUS 5.0 now includes Digital Audio Corporation's CARDINAL MiniLab Suite of forensic audio plug-ins, including:

These audio plug-ins add a comprehensive set of audio forensic tools to VideoFOCUS. They can be applied to any audio in the application, including audio contained within a video session or an audio-only session.

QuickEnhance Audio Plug-in

VideoFOCUS 5.0 now includes Digital Audio Corporation's QuickEnhance audio plug-in. QuickEnhance provides easy-to-use filtering options for noise removal to help improve speech intelligibility and clarity in noisy audio. QuickEnhance is equipped with the following features:

Snapshot Feature

VideoFOCUS 5.0 includes a snapshot feature that allows the user to capture, as a still image, exactly what is being rendered to the screen. This is ideal for quickly zooming, panning and cropping an image detail into a stand-alone still image suitable for export or further processing.

New Look and Feel

VideoFOCUS 5.0 has been given a new interface theme to modernize the appearance of the application and align it with other Salient Sciences products.

Introduced in VF 4.6

Fast Import For Many Media Formats

VideoFOCUS 4.6 has eliminated the need for transcode for a wide variety of video media formats. As a consequence import time for long duration or large frame size video are substantially reduced (in certain cases two orders of magnitude). Furthermore the disk space use for the import of such media is reduced substantially.

VideoFOCUS import now consists of a copy phase to create a copy of the media within the project storage with time taken comparable to a regular file copy and if required an indexing phase to produce an accurate frame index for those media types lacking a native frame index. Indexing is typically needed only for the import of media originally produced for live streaming.

Improved Player Performance for HD Video

This version includes a revised architecture for media handling which supports a more efficient approach to playing video. This provides notable improvements in player performance particularly for imported media with temporal compression and HD (1366x768 line) and higher frame dimensions.

The new import facilities allow for the efficient import of HD and larger frame sizes however many processing operations are intensive and for HD sized video require considerable computation per frame. Although HD video player performance is greatly improved, depending on the processing operations applied, playing processed HD video may result frame skipping if computation cannot keep up. If necessary the "self contained" option in the modify dialog can be used to create a rendered copy of the processed video to improve player performance.

Simplified Export

The export dialog has been upgraded to present a goal oriented approach to selecting export formats and codecs. The new dialog offers a set of default export profiles that represent appropriate choices of format and video and audio codecs for specific tasks such as full quality archive, email and high quality reduced space exports.

Export Profile Editor

Facilities are included under an "Advanced" panel to allow users to define their own export profiles appropriate for their export needs. Profiles can be constructed from a number of different media formats and accompanying audio and video codecs. User created profiles become available exactly like predefined system profiles as selectable output types in the export dialog.

When creating a user defined export profile consideration should be given to the fact that not all combinations of formats and codecs will create valid files. It is therefore suggested that any new profile is tested with familiar media and the anticipated media player to confirm that output is as expected before using more generally for export.

Of the three common players, QuickTime, WMP and VLC, we have found the VLC player to be the most accommodating in handling different formats, codecs, media frame rates and dimensions etc.

Introduced in VF 4.5

Audio Support

VideoFOCUS 4.5 introduces support for audio manipulation and processing for audio that is present in a video and for audio that is standalone.

Audio Import

The import capabilities of VideoFOCUS are extended to allow for the import of audio media files. When supported media files containing audio are selected in the import dialog the import review player can be used to play the file. When opened an audio item will be added into the captured and imported session area.

Audio Project Items

Audio only media that is part of a VideoFOCUS case is displayed in the captured and imported session area and depicted by a speaker icon. Audio items can be viewed in the player in the same way as video items. The player shows a visualization of the audio signal that follows the play head position and the zoom control can be used to view fine structure of the audio signal down to the individual sample values.

Audio Extract and Combine

Extract

Video containing audio offers an additional "Extract Audio" action from the item popup menu or from the processing menu. The extract audio action will create an audio only project item containing all the audio tracks from the selected video.

Combine

When two or more audio items or a video item and one or more audio items are selected the combine popup or processing menu item will be available. In the case of an all audio selection the combine action will produce a new audio item containing all the tracks of the selected items, extending shorter duration audio items by silence where necessary. In the case of a combine with video the selected audio items will either be clipped or extended to match the duration of the video.

Audio Modification

The modify panel now supports basic audio modifications on audio or video items. When modifying a video item containing audio the panel contains an additional "Audio Properties" tab containing the controls. Changes in audio properties are reflected in real time in the modify player.

Audio Processing

Audio filtering is now available for audio items and video items containing audio. Four audio filters are offered and can be selected through the Filter->Audio menu. The interface is the same as the video filter, offering original and processed displays, with the processed display player providing a real time update to audio and signal visualization for changes made to any of the processing parameters.

Most audio filters also offer the option of a 200Hz high pass filter as a pre-stage to the main filter functionality

Media Player Updates

Looping and Selection Play

"Loop Play" and "Play Selection" menu items are now in the player popup menu and the view menu of the undocked player window.

The play selection will make the player play only the selected section of the video or audio instead of the entire duration of the media.

Loop play will cause the player to loop continually over the section selected for play. If loop play is selected when a selection of more than one frame is present the play selection option will also turn on resulting in the looping play of the selected section of media.

A shortcut to the loop play menu item is provided by a loop button in the player to the right of the time selection slider.

Volume Controls

The media player interface now provides a volume control and an audio mute button.

Audio Signal Visualization

When the media player is used to view video containing audio the "Audio Signal" popup menu item will control the visualization of the audio signal as a waveform. Each channel is displayed with channel 0 being the closest to the bottom of the player window.

The signal visualization is limited to a maximum time window of 10 seconds centered around the current displayed frame. The specific position in the audio signal corresponding to the currently viewed frame is indicated by the vertical white bar. The visualized audio signal time window adjusts according to the time scale sensitivity selected by the timescale zoom slider control

Introduced in Version 4.1

VideoFOCUS Video Format Converter

The VideoFOCUS 4.1 install now includes the VideoFOCUS Video Format Converter plugin install. This plugin provides extensive support for a wide variety of media formats and codecs and provides VideoFOCUS with the ability to import video with accompanying audio from a wide range of media file types.

If the VideoFOCUS Video Format Converter installation is successfully completed during the VideoFOCUS install no further action is needed to use this capability. VideoFOCUS will use this plugin to transcode all non MOV files to an uncompressed MOV format for subsequent processing within the application.

Batch Image Import

VideoFOCUS now supports the batch import of images.

Image Sequences

VideoFOCUS now provides full support for the import of image sequences. Multiple images, typically representing a time sequence, can be imported directly and will be transcoded at a user specified frame rate into a video. This capability is available when using either the media import dialog or drag and drop import.

VideoFOCUS will automatically detect cases where multiple images could be considered as an image sequence and will order the images intelligently according to the filename name of each image in the sequence. An option to handle such sequences as a regular batch image import is also available.

Unified Media Import Dialog

The image and video import dialogs have been unified into a single new import dialog. This dialog allows for the individual and batch import of both images and video and the import of image sequences. To make selecting media to import simpler the dialog contains a visualization panel with a media player that allows for the instant review of video and images prior to their import.

If a set of images is selected all with a common file type the dialog will offer the option either to import them as individual images or as an image sequence.

Drag and Drop Import and Export

VideoFOCUS now supports drag and drop for media import and image export.

Drag and Drop Media Import

VideoFOCUS will import media files that are dropped into the application. Individual or multiple video files can imported by dragging from the desktop or a file explorer and dropping them into the "Captured and Imported Sessions" area. Similarly individual or multiple image files can be imported by dropping them into the "Session Stills and Frames" area.

Collections of two or more image files of the same type can be also be dragged into the "Captured and Imported Sessions" area and they will be imported as an image sequence. When these items are dropped VideoFOCUS will prompt for the desired frame rate for the video.

Drag and Drop Image Export

VideoFOCUS can export video frames and images using drag and drop. When frames are selected from the video thumbnail view or images from the "Session Stills and Frames" area they can be dragged out of the application and dropped into a suitable location such as the desktop or a file explorer window. The images will be saved in the image file format specified in the Edit->Preference dialog.

Internal Drag and Drop of Images

In addition to import and export drag and drop, drag and drop can be used to copy individual or selections of frames from the thumbnail video view into "Session Stills and Frames" view. Frame thumbnails may also be dropped into "Captured and Imported Sessions" to produce a video.

Administrator Privilege No Longer Required

VideoFOCUS no longer requires elevated privileges when running.

This change allows for more flexibility in user security configuration on systems where VideoFOCUS is installed and reduces the risk of inadvertent modification of protected material. It does however mean that permissions on the file system must be configured sufficiently to allow each VideoFOCUS user full control over areas designated for storage of their cases or for any cases that they wish to open. (VideoFOCUS does not yet support read only access to cases). In order to support per user configuration all settings established from within VideoFOCUS including open case lists are stored on a per user basis.

Introduced in Version 4.0

Cases

VideoFOCUS 4.0 introduces the concept of cases to allow for better organization and management of separate work efforts. Each case is displayed as a tab of the main window and the contents of each tab are the familiar 'Sessions' and 'Stills' windows of previous versions of VideoFOCUS.

The following case related actions can be found under the 'File' menu.

Notes on Case Media

Video and image data may be freely copied between cases (using copy and paste). When pasting into a different project VideoFOCUS will create a copy of the media. This ensures that the data will be still be available in the destination project if the source project is deleted or relocated.

The same applies for imported media. VideoFOCUS 4.0 will create its own internal copy of imported images and video and will not require access to the source material after a successful import.

Titles in Edit

The session editor introduces new title facilities to allow for the addition and editing of titles in any movie in VideoFOCUS. (Editing can be started by a right click 'Edit' on an existing session or through the 'File'->'New Session' menu action.)

The following titling menu actions are available in player window when editing a session

The 'New' and 'Edit' actions bring up a title editor. Just as in editing with a typical text editor title text can be entered directly into the editor and will appear at the cursor location. The following elements control the title's appearance.

To adjust existing text the text must be first selected (in the typical way for a document editor) before the 'Justify' or 'Size' values are changed.

Images

Images can now be imported into VideoFOCUS. Images are imported using the 'File'->'Import Image' action and will appear in the 'Session Stills and Frames' panel. Once imported the image is treated just like any other still and can be processed as such.

Other Features

A rotation option has been added to the modify panel ('Processing'->'Modify'). This allows for the arbitrary rotation of both images and video by a specified number of degrees.

An invert option has been added to the blur filter. ('Processing'->'Filter'->'Blur') which makes all areas other than the mask areas blurred. This can be used in conjunction with mask tracking to highlight individual objects within a moving sequence.

The WAV file type option has been added to movie export. This will be available if the session being exported (or any session in the case of a batch export) contains audio. It will produce a WAV format audio file.

The screen capture source selection dialog can now be resized to allow for more precise selection of the capture window area.

Change Log

This table will be updated with information on fixes as new versions of VideoFOCUS Pro products are made available for download.

Note that the changes listed cover all VideoFOCUS products and not all changes will affect VideoFOCUS Pro

Offline Licensing

VideoFOCUS attempts to contact the SalientSciences licensing server when necessary to update the product activation code to match the version of VideoFOCUS being used. When the machine running VideoFOCUS does not have an internet connection the activation code update requires the manual approach as described below

When your license is dongle based

Dongles can only contain an activation code for one version of VideoFOCUS at a time.

The simplest way to update the dongle to the correct activation code is to find any computer with an internet connection (e.g. web/email machine). Install the desired version of VideoFOCUS on that machine, insert the dongle, make sure the dongle light is on and then open VideoFOCUS and close again once the application starts. At that point the dongle will be updated to contain an activation suitable for use on any machine with that version of VideoFOCUS irrespective of network connectivity (e.g. an offline office workstation)

Alternatively you can install VideoFOCUS on your workstation, insert the dongle, make sure the light is on, then start VideoFOCUS. Because your workstation does not have an internet connection you will be prompted through a set of steps to complete the activation (and therefore the update of the dongle). These steps will involve saving a small html file and transferring it to an internet connected machine so as to open it and obtain an activation code from our license server. This code should be saved and returned to your offline workstation and then copied and pasted into the activation dialog.

To avoid a need to update dongle activations every time you switch between VideoFOCUS versions on the same machine VideoFOCUS stores a copy of the dongle activation data for its version in a local cache on the machine. By relying on the cached activation data, that version of VideoFOCUS can work on that machine as long as the dongle is present, even if the dongle contains an activation for a different version.

When your license is not dongle based (a.k.a a soft license)

Install VideoFOCUS on the workstation you intent to use it on, then start VideoFOCUS. Because your workstation does not have an internet connection you will be prompted through a set of steps to obtain an activation code and complete the activation. These steps will involve saving a small html file and transferring it to an internet connected machine so as to open it and obtain an activation code from our license server. This code should be saved and returned to your offline workstation and then copied and pasted into the activation dialog.

Log Files

VideoFOCUS log files can be found in the following locations. In each case there may be more than one log file each with a different integer value for [n]. If providing logs to help resolve a problem it is generally useful to provide all files matching the patterns described below.

%USERPROFILE%\java[n].log
and
%LOCALAPPDATA%\SalientSciences\VideoFocus\Logs\videofocus[n].log
or
%APPDATA%\SalientSciences\VideoFocus\Logs\videofocus[n].log

In a standard windows installation these will resolve to the following paths

C:\Users\[username]\java[n].log
and
C:\Users\[username]\AppData\Local\SalientSciences\VideoFocus\Logs\videofocus[n].log
or
C:\Users\[username]\AppData\Roaming\SalientSciences\VideoFocus\Logs\videofocus[n].log

Note that the text %USERPROFILE% and %LOCALAPPDATA% or %APPDATA% can be used in the path bar of a windows file explorer to facilitate easy access to the actual locations (especially if their values are not standard)
