Fastest way to cut and remove parts of a video
It is possible that your software is re-encoding the file. If you just want to copy a 5 second chunk of the movie, you can use this command:
ffmpeg -i YourFile.mp4 -ss 00:10:25 -t 00:00:05 -acodec copy -vcodec copy Output.mp4
- Where
-i
is the name of your file. -ss
is the start position in Hours:Minutes:Seconds-t
is how long a clip you want - again in HH:MM:SS- The
acodec
andvcodec
tellsffmpeg
just to copy the file without changing it at all.
That's about the fastest you can get it.
