I'm new to FFMPEG so I need some help from some professional users.
I have a relative simple task:
I have some MOV files with a single audio track that contains 16 channels. I want to remove the last 14 tracks and create a file with copied video (no reencoding) and just the first two audio channels. The 14 last tracks should be discarded.
I found a lot of tutorials for creating 5.1 files etc. but not what I need. Could someone please point me to the right direction or even post the command to accomplish this task?
Here is the info from the source file if that gives you any help:
