Any FFmpeg gurus here? need help with command generating thunbs.
So I have this command that will make 4 thumbs for each video. The problem is thumb starts at certain position and makes 4 frames back to back. How would I space them out lets say 30 seconds apart or say make 4 thumbs for each video equally spaced.
This:
for i in *.mp4; do ffmpeg -i "$i" -an -ss 00:00:30 -an -r 1 -vframes 4 -s 160x120 -y `basename $i .mp4`_%d.jpg; done
Thanks
