user27194: I want to cut an existing movie and want to remove all the language track from it.
The thing is when I start to edit the movie, Premiere Pro just picks up some language, which is not suitable for me. How do I remove all the soundtracks except the one I need?

ffmpeg -i  -c copy -an video_only.mp4

How do I remove all the soundtracks except the one I need?

ffmpeg -i  -c copy -map 0:a:1 specified.mp4
