Split video files (.mp4, .avi, .wmv, .mkv)

[marfin2]

Hi,

I try to split videos on Ubuntu 12.10 and I found MKVmerge for splitting matroska (.mkv) and Avidemux for splitting avi files.

Could you tell me what software (or commands) I can use to split .mp4 and .wmv files please ?

Thanks for your help.

Hello,

you can try ffmpeg for the mp4 files

ffmpeg -acodec copy -vcodec copy -ss START -t LENGTH -i ORIGINALFILE.mp4 OUTFILE.mp4

found it in less then a minute google search http://askubuntu.com/questions/35605...ng-an-mp4-file

Avidemux can handle wmv since version 2.3.0 if you have all codecs installed.

sudo apt-get install non-free-codecs

in sum two minutes goolge, why can't you do that.

Thanks for your help.

For FFMpeg, that I use, I consider that it's not a really split, but a conversion that allows multiple small files in output. The problem is that conversion is much longer than a split.

I didn't know for wmv and avidemux, thanks !

I don't know about wmv. I suppose you could just use VirtualDub in Wine/Windows. Avidemux should work with mp4, surely?

hi marfin

you can use ffmpeg or mencoder to split video file in multiple sections


use same input file add "&&" between cuts and do as many sections as you need to
First time entry is where you start from. Second time entry the duration you require

ffmpeg -i INPUT.mp4 -ss 00:35:54 -t 00:04:12 -vcodec copy -acodec copy OUTPUT1.mp4 && ffmpeg -i INPUT -ss 01:14:14 -t 00:14:10 -vcodec copy -acodec copy OUTPUT2.mp4 && etc...

or

mencoder -ss 01:00:00 -endpos 00:05:56 -oac copy -ovc copy INPUT.mp4 -o OUTPUT1.mp4 && mencoder -ss 01:20:00 -endpos 00:05:56 -oac copy -ovc copy INPUT.mp4 -o OUTPUT2.mp4 && etc...

iN MY PERSONAL experience mencoder is more stable for this task

Thanks a lot everyone.
And mea culpa for my for my wrong remark on FFmpeg : if we use "-vcodec copy -acodec copy" and we have the same format in the input and output, FFmpeg split correctly the file (and don't convert as I thought).
rai_shu2> I can't use VirtualDub beacause I need use tools with command lines, but thanks for the idea.

Just one question : why when I use FFmpeg to convert (not to split), even if I put the bitrate video and audio, the bitrate video (but not the bitrate audio) is out from metadata ?
