I'm having some trouble with slow braw playback on Premiere Pro. I'm working with a 6K Braw 5:1 on an HD timeline and have downloaded the Blackmagic Raw plugin for Premiere Pro. My computer build includes an
NVIDIA GeForce RTX 3090,
AMD Ryzen 9 3950X 16-Core Processor,
64GB (3200) RAM.
The playback on the timeline is really slow, and some things just don't work. It's strange because the playback on the source window is fine, but it's slow on the timeline. I also noticed that the playback seems to be better when the sequence settings are at 6k rather than HD, though it's still not great.
Interestingly, when I use DaVinci Resolve on the same computer, the playback is fine. I did a Blackmagic RAW speed test and got 93FPS on 6k 3:1, 8k 60FPS, and the Disk Speed Test showed that read and write is okay up to 12K DCI 60.
My CPU maxes out at 70%, and my RAM is at about 50%. GPU is at about 12%, but my disk isn't reading anything which is weird.
It even plays back smoother in just the normal Braw Player. Any idea why this is happening?
