When I just want to have a certain part of a video, I can do something
like:
ffmpeg -y -i input.MTS \
-ss 00:08 \
-to 00:17 \
-acodec copy \
-vcodec libx264 \
-preset veryfast \
output.mp4
But what if I want several parts of a video in my video?
Do I need to cut the different parts out of the video and concatenate
them, or is it possible to do it with one command?
Using concat filter.
That is exactly what I already know: cutting the different parts.
Probably one command for each part and then concatenate them.
So n + 1 commands.
My question was: can it be done with one command?
Please have a look at
https://trac.ffmpeg.org/wiki/Concatenate
"Concat demuxer", "Concat protocol" and "Concat filter" are three
different things.
You did use the concat demuxer. Now if you want to do all in one line,
you must use the concat filter.
