Top Forums UNIX for Advanced & Expert Users trim 165 MB video clip with ffmpeg (only last 3 minutes) Post 302575528 by mirni on Tuesday 22nd of November 2011 02:30:00 AM
Old 11-22-2011
I was able to trim a test video on my machine with the syntax you provided, so I think it is correct. What I meant in the previous post was to double check the duration of the video (launch it in mplayer or some other player and skip to the end, see what is the duration). It may be that the video is shorter than 52 minutes, in which case you are telling ffmpeg to skip beyond the end of file.
Is it working, if you are trying to trim the first 3 minutes? or the 3 minutes somewhere in the middle of file?
Is it working with some other .flv file?
