Multicam Sequences Using Compositing/Green Screen

I have a very specific workflow that really drags down Premiere, and I’m wondering if anyone else works the same way and has come up with a speedy workflow.

I shoot mostly interviews on green screen using three cameras. When I go to edit, I composite each angle over the background, and then create a multi-cam sequence that contains each angle so I can “switch” between angles during the interview.

This really bogs down Premiere. I have to hit “play” multiple times for it to start playing. If I have to adjust a cut, it takes forever, and then try to start playing again can take 10-45 seconds for the sequence to begin playing again. 

I have an otherwise fast machine. I’ve tried turning off FX while editing. This makes little difference because what seems to be happening is that Premiere is still factoring in the composited version in the background. You can see it turning the FX on and off while making changes or hitting “play”.

I reduce playback to 1/8 resolution. Slightly better, but not really making my life easier in any way.

Does anyone else work like this and have a good solution? I was thinking maybe I could use markers and go through the sequence without going to the multi-cam function and marking cuts that way and then using those markers to automatically make cuts and switching angles using the shortcut menu? I’ve been dealing with this for years so I’m used to it, but have finally decided that I need to try to find a good solution so I’m not getting so bogged down.

TIA
