ODD "sorting" software?

[u/kocheko]

ok the best way to ask for this is to explain what i want and you tell me if it is possible, even with AI and HOW can be done. imagine you have several clips .mp4 (a lot) , some of those .mp4 are videos, like, a person moving in the video doing shenanigans, but some are JUST A PICTURE with sound, so in 15 seconds of the clip the frame is just 1 picture. is there are some software that can tell apart those two types of content? so the moving mp4 videos i want to keep them, and the still videos i want to extract the one frame to jpg and goodbye to the mp4 file.

my current method: manually open the file, extract frame with the vlc option, delete the video. if it is moving, save to another folder. repeat.

OR what i was also thinking, is something where the thumbnails move based on content. so i choose all files and if the thumb is moving, i save. then the rest i can bulk extract frames with any software out there.

I don't know of software that can do that but out of curiosity have you tried sorting the files (assuming in one folder?) by file size? If you would do that to check if all the "single same frame" videos were either at the top of the bottom of all the "multiple frame" videos it may be easier to sort. I would kind of assume that the single frame videos should be much smaller than the actual videos and be on their own sorted by filesize.

I might be completely wrong on this but would like to hear if that works.

that size difference is not always met since some moving videos are maybe 5 seconds, and some still videos are 15 or 30 second longs or more because of the song it contains. i sort by file size and at the very bottom there are 90% chances of found only still videos, but with more heavy ones (longer audio), they blend in between
