Split video file. FFmpeg

Operating systems : Windows, Linux

Split video file by ffmpeg:

There are two ways how to split video files by ffmpeg. The first one is good in itself, more than that - it is faster, but sometimes creates output files with certain flaws. So for those cases there is the second way of splitting video files: it is considerably slower, the output files are bigger, but it seems they are always of the same quality level as input files used.

Way : 1

ffmpeg -ss <start> -t <duration> -i in1.avi -vcodec copy -acodec copy out1.avi

Way : 2

ffmpeg -ss <start> -t <duration> -i in1.avi -sameq out1.avi

- <start> - the beginning of the part of a video ffmpeg is to cut out. Format: 00:00:00 - hours:minutes:seconds - hh:mm:ss

- <duration> - the duration of the part of a video ffmpeg is to cut out. Format: 00:00:00 - hours:minutes:seconds - hh:mm:ss

Examples

ffmpeg -ss 01:19:00 -t 00:05:00 -i in1.avi -vcodec copy -acodec copy out1.avi

ffmpeg -ss 01:19:00 -t 00:05:00 -i in1.avi -sameq out1.avi

- ffmpeg cuts out a part of the video file starting from 1 hour 19 minutes 0 seconds. The duration of the video sequence cut out is 5 minutes 0 seconds.
