Verify digital signature of exported videos
In the tab as shown below, users can authenticate videos with digital signatures.
Follow the steps below to complete the verification.
• Select any video from the Data List and click at the bottom, then the “Playback”
window will be displayed returning a GOOD or BAD signature result in the
field. A GOOD signature indicates the exported clip has not been altered, whereas a
BAD signature means the video might be changed at some point.
• Alternatively, click to select the *.gpg, *.drv (or *.avi), *.sig files, which belong
to the video to be authenticated, respectively. After all files are selected, click
button to start verifying digital signature.
