I want to have MakeMKV encode the flac audio using only the nessacary bits, no more of that 24 bit audio takes up 32 bits stuff, I found how to do that in FFmpeg using the pcm_s24le flag, but how can I make sure that 16 bit audio is encoded as 16 bit instead of 24?

When I figure that out I plan on editing my conversion profile thread, and it's in the public domain, anyone can use it for whatever.

a 16-bit file converted to 24-bit and then encoded in flac will be exactly the same as if 16-bit file encoded directly.
