Need help creating batch process for audio track swap

[Squintz82]

Hi all,

I need a bit of help since I'm not really familiar with Avidemux or the batch command line commands.

I have a large project where I need to remux over 500 movies. I have all of my movies saved with dual audio tracks (AAC stereo & AC3 5.1). Originally I had been creating the primary (#1) track as AC3. But recently I've learned that I need to make the AAC audio track the primary (#1) audio track.

In Avidemux, I don't need to convert anything (copy video and copy audio). But the only change I make is Audio > Select Track > (Track 1 = Track 1) and (Track 2 = Track 0) and (language = English for both tracks). Then save the output filename the same as the input.

Is there a batch or command line command that can accomplish this without needing to do this manually for each movie?

Thanks in advance!
