Thanks Moritz/Carl. I’ve got something working using the select method and vsync:
ffmpeg -i example.mov -f image2 -vsync vfr -vf "select='not(mod(n,17)')" -vframes 10 preview-%d.jpeg round(number of frames in video/number of frames wanted) = 168/10 = 17 I also added the vframes setting to limit the number of frames, because due to rounding we might sometimes generate one more frame. I feel like I have a lot more to learn :) _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
