Have a look also ffmpeg Doc, or this wiki page. I think you can use the following command now.įfmpeg -i inputFile -vcodec copy -acodec copy -ss 00:09:23 -to 00:25:33 outputFile For high quality video and audio, read the x264 Encoding Guide and the AAC Encoding Guide, respectively.įor example: ffmpeg -ss -i in.mp4 -t -c:v libx264 -c:a aac -strict experimental -b:a 128k out.mp4 If you leave out the -c copy option, ffmpeg will automatically re-encode the output video and audio according to the format you chose. This won't harm the quality and make the command run within seconds.įor more info, see How to cut a video, with re-encoding

-c copy copies the first video, audio, and subtitle bitstream from the input to the output file without re-encoding them.

For example, if you cut with -ss 3 -i in.mp4 -to 5, the output will be five seconds long. Note that if you've used -ss, you have to subtract this from the -to timestamp. Instead of -t, you can also use -to, which specifies the end time (needs -copyts if -ss is before -i, for faster seeking).-t specifies the duration of the clip (same format).Use this to cut video from to : ffmpeg -ss -i in.mp4 -to -c copy -copyts out.mp4

Use this to cut video from for : ffmpeg -ss -i in.mp4 -t -c copy out.mp4 Packaged versions from various distributions are often outdated and do not behave as expected.

Make sure you download a recent version of ffmpeg, and don't use the one that comes with your distribution (e.g.
