Just wanted to share with anyone who has run into the same issue of video thumbnails being all black (or a solid color for that matter) because of the first frame of the video. In v1.7, changing the below lines will fix this issue and leverage FFMPeg’s ability to pick a thumbnail based on “context”. Or, replacing “-vf thumbnail” with something like “-ss 5” will generate a thumbnail that is 5 seconds into the video. “-vf thumbnail” is a better option as not all videos may necessarily be > 5 seconds long.
Hope this helps!
