in/out are in units of frames. So just calculate the number of frames for your in/out points. I assume your timecodes above are in HH:MM:SS format. For #1 above: ( ( 30 x 60 ) + 36 ) x 29.97 = 55024 So you would run: melt test.mp4 out=55024 -consumer avformat:test2.mp4 For #2 above: ( ( 50 x 60 ) + 14 ) x 29.97 = 90329 ( ( 55 x 60 ) + 6 ) x 29.97 = 99080 So you would run: melt test.mp4 out=90329 test.mp4 in=99080 -consumer avformat:test2.mp4 ~BM ------------------------------------------------------------------------------ Own the Future-Intel® Level Up Game Demo Contest 2013 Rise to greatness in Intel's independent game demo contest.
