In case this was not clear, I meant: ffmpeg -i "original.avi" -ss 0:10:00 -t 0:00:30 "output1.avi" -ss 0:15:00 -t 0:00:30 "output2.avi". > I tried that and it creates output files with 0 bytes. > > Here was my input: > ./ffmpeg -i "/Users/user/Documents/original.MP4" -vcodec copy -acodec > copy -ss 00:10:10 -t 00:00:30 -vcodec copy -acodec copy -ss 00:24:15 > -t 00:00:30 "/Users/user/Documents/output1.MP4" > "/Users/user/Documents/output2.MP4" That looks very different, and if you would not top-post (which is considered rude here), you would have had a chance to see it yourself. > Here was the output: > ffmpeg version 0.8.git-08d2cee, Copyright (c) 2000-2011 the FFmpeg developers This is old, please try current git head.
