After trying to do this in the usual suspects all listed by others here I ended up using Kino. I've struggled with this same issue, having a large video file that I want to cut and save as separate scenes. You can force all the needed keyframes before segmenting. This usually works well enough for most cases, but if you need precise video segments, see How to extract time-accurate video segments with ffmpeg?. Note that ffmpeg will only split on keyframes. # Cannot have colon in the filename with ffmpeg I have modified it a bit to include video formats and to avoid transcoding. (copying instead), I suggest a yad script to be run from a desktop file launcher. Or avconv -ss 0 -i source.m4v -t 100 -vcodec copy -acodec copy part1.m4vĪvconv -ss 100 -i source.m4v -t 100 -vcodec copy -acodec copy part2.m4vĪvconv -ss 200 -i source.m4v -t 100 -vcodec copy -acodec copy part3.m4vĪvconv -ss 300 -i source.m4v -t 100 -vcodec copy -acodec copy part4.m4v

Or ffmpeg -ss 0 -t 100 -i source.m4v -vcodec copy -acodec copy part1.m4vįfmpeg -ss 100 -t 100 -i source.m4v -vcodec copy -acodec copy part2.m4vįfmpeg -ss 200 -t 100 -i source.m4v -vcodec copy -acodec copy part3.m4vįfmpeg -ss 300 -t 100 -i source.m4v -vcodec copy -acodec copy part4.m4vĪVCONV avconv -i input.avi -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 output1.aviĪvconv -i input.avi -vcodec copy -acodec copy -ss 00:30:00 -t 00:30:00 output2.aviĪvconv -i input.avi -vcodec copy -acodec copy -ss 01:00:00 -t 00:30:00 output3.avi

For example:įFMPEG ffmpeg -ss 00:00:00 -t 00:30:00 -i input.avi -vcodec copy -acodec copy output1.aviįfmpeg -ss 00:30:00 -t 00:30:00 -i input.avi -vcodec copy -acodec copy output2.aviįfmpeg -ss 01:00:00 -t 00:30:00 -i input.avi -vcodec copy -acodec copy output3.avi I was going to mention commands like ffmpeg or avconv (The new one) which can OBVIOUSLY split files into groups.
