With ffmpeg -i CYD.mp4 -vf select='not(mod(n\,1500))' CYD_%03d.jpg I got 150,000 pictures with reduced quality (~12 kB). Weird!!! But with ffmpeg -i CYD.mp4 -r 1/60 CYD_%03d.jpg I got 78 pictures with good quality (~70 kB). Picture CYD_001.jpg and CYD_002.jpg were black, CYD_003.jpg was frame 00:00:53. Also a little weird, the video is 1:16:20 long. but I can live with that. -Ulf _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
