  • Find/extract the frames which are different in two videos

    24 novembre 2022, par Greendrake

    I have two H.264 video files roughly 30GB each, with 256291 frames in each. Most, if not all, frames in the 1st video appear identical to their counterparts in the 2nd video. That said, the video content is seemingly almost (maybe completely) identical.

    


    The raw H.264 streams extracted from the video files are actually supposed to be identical but they are not : one is bigger than the other by about 2MB. So, it seems like there ought to be some differences in the picture somewhere.

    


    I have used the following command to extract a frame each 0.5s from the files and then compared the frames' md5 hashes. All 21356 frame files extracted from the first video exactly match their counterparts from the second video.

    


    for i in {0..21356} ; do ffmpeg -hide_banner -loglevel error -accurate_seek -ss `echo $i*0.5 | bc` -i video.mp4 -frames:v 1 frames/period_down_$i.bmp ; done


    


    So, the odds that the video is anyhow different are low. But not 0% chance as the one or a few different frames could just fall outside of the 0.5s picks that I tried.

    


    Is there any smart way to find/extract the diffing frames only ?

    


    I could extract all frames and compare them but that's not smart at all and would take lots of time / disk space.
