Hello,
I'm looking for a ffmpeg command to split a mp4 file without re-encoding it.
Someone here have done that?
Thanks

I know, I searched on google but I forgot to mention that I need the command line to work with ElevatedX, my bad.

-ss 1:00:00 -t 2:00:00 -acodec copy -vcodec copy

where 1:00:00 is the start time and 2:00:00 would be the end time.
-ss and -t need to remain in THAT order and need to be at the beginning of the command line. even before your -i.

i dont know the specifics of what other videos you are delivering so i cant help you with the full command line input. if you have an existing one youd like to port, post it here and i can fix it for you.

use the copy command so it doesnt re-encode like so

Code:

ffmpeg -ss 00:00:00 -t 00:50:00 -i largefile.mp4 -acodec copy -vcodec copy smallfile.mp4
