I have some files that have multiple audio tracks and several subtitle tracks, all of which are marked default. I’d like to remove the default from all the subtitle tracks and all-but-one of the audio tracks (and possibly move the audio track to be the first track). How would I do that?
I believe you can remove (default) with -disposition:stream 0 so, if you have three subtitle tracks, all marked as default, and you want only second with that mark, you’d do something like this:

mkvtoolnix is the best tool for this stuff. iirc ffmpeg has some limitations in this area
Okay, looks like you can do it in ffmpeg, but you have to map every audio stream individually in the command to rearrange them.
Pretty decent chance ChatGPT can answer this for you.
I believe you can remove (default) with
-disposition:stream 0so, if you have three subtitle tracks, all marked as default, and you want only second with that mark, you’d do something like this:ffmpeg -i input.mkv -c copy -disposition:s:0 0 -disposition:s:2 0 output.mkvAnd if you want to mark a stream as default, you do
-disposition:stream default.
