Because of FFmpeg's license and legal considerations, we cannot provide the FFmpeg library with our product, but you are able to download it on your own. Please read the FFmpeg's legal page at https://ffmpeg.org/legal.html.
On this page, select one of the windows EXE files (for example: “Windows from gian.dev”)
On the page find a release section and download the full release.
Extract the FFmpeg archive (ffmpeg-3.2.2-win64-static.zip in this case) on your computer. To do so right-click the FFmpeg archive, select "Extract All..." and then press the "Extract" button (you can also use another file archiver such as 7-Zip or WinRar).
After extraction, you should see a folder with the same name as the archive. Inside you should see the "bin" folder with ffmpeg.exe. If you don't see it, Microsoft Windows or your file archiver probably created a second folder with the same name as the archive.
Copy or remember the path of the "bin" folder.
Open MOBILedit Forensic Express.
On the "Choose type of export" page, select Specific selection.
On the next page select the Video option (1.) then Browse for ffmpeg.exe (2.) and finally navigate to the folder from point 5, select ffmpeg.exe and click Open (3.)
In the screenshot above there is a "Storyboard settings" located inside the red square, which is shown after successful installation.
A storyboard is activated by selecting the "Generate storyboard" option.
The first screenshot is generated at the start of the video.
The default setting generates 12 screenshots per video, and the following options are available:
Fixed image count
This option makes a fixed number of screenshots based on the "Number of images" setting, with one exception when the video is shorter (in seconds) than the specified number of images. If this is the case, one screenshot is created for every second of a video.
Fixed time interval
This option will create one screenshot per interval of selected duration (for example 1 screenshot at every 5 seconds of the video), which is done by using the "Interval" option. Minimal duration is one second. The "Maximum number of images" limits the maximum number of images to be created.
Delete the folder where ffmpeg.exe is located.
