Multicam struggles with working with 3 or more cameras. I dont have the time to create proxies and dont like using them as they create even more problems. When editing a multicam I want to be able to be able to see all my cameras and edit in real time. I have to pause and play every 5 seconds or so to edit even at 1/4 resolution. Fix please
Seriously? I wish some posts could be taken down, to declutter things here.
You gave no information at all on your media and system, to indicate whether you Should be able to edit this material in real-time in the first place.
Without establishing that, it's as relevant as saying "I want to be able to teleport to London now. Fix please"
What media format are these, what's your CPU and GPU, and is your storage fast enough to pull these 3 data streams - simultaneously.
Then someone can see if your setup will be UNABLE to do what you need - or if it's a Premiere optimization problem.
