Wow lots of reading for you to do but I understand where you’re coming from.
This is fast turn around so you could just AMA link but that might have a lag on the system since its multi cam. I would AMA Link in a formatted project native to your clips, then consolidate and send those high res media transcodes to an external drive. Then edit. If you need to you can Mixdowns but you should have to. Also don’t convert the frame rates when you load!
