Really? That’s odd! Firstly, thanks for the heads up on catching any audio weirdness, it’s appreciated.
Are you listening to the audio downmixed to stereo maybe? That particular transition got worked on a fair amount, specifically to make sure the center channel didn’t get lost in the sauce vs the L and R music coming in underneath it. I did also test it quite a bit in 5.1 (and also tested it downmixed to 2.0 in my headphones) - but I didn’t actually check it to see what would happen if a streambox or a receiver handled the 5.1 to 2.0 downmix to speakers on its own.
edit: Okay, I just checked the 20:04 point by streaming the edit from my home server to a screen where I can only listen downmixed to stereo (on headphones I dont’ normally use! - I don’t know if/when I’ll be doing another edit but I need to keep this in mind for if/when I do as part of the pre-publish checklist, LOL), and before I even continue - at 20:04 her audio is actually still the theatrical mix in the center channel anyway, so any jumps/dips in the center there is just the movie being the movie - although the L/R is starting to blend the original audio w/ the replacement cue shortly after that point (I’d have to open the ProRes when I get home to see if that cue starts to come up in the C as well as the L/R, I don’t 100% remember off the top of my head rn) right around Mon saying “of this… superweapon.” - at that point I cut the rest of the line and bring up the full replacement cue.
I did notice after that, the two lines she and Jyn trade (“And if I do it?” “We’ll make sure you go free.”) do sound a little lower due to the downmixing (Not as much L/R info to fold back into the Center due to the isolation processing I used) but at 20:04 - that’s just what happens in the movie? I didn’t actually do anything to her or Draven’s dialog there, it just plays as it did in the theatrical.
