Welcome to Adobe Pr … this has been a major issue for many of us for years (ever since CC 2017). In most cases many recommend converting your source files into some other codec like ProRes. I found this to be too time consuming and often didn’t resolve the performance problems with Pr and used up my 80TB of storage rather quickly.
To work around the poor codec reliance that Adobe have, I do the following:
1. Convert all ingested media to Proxies (either Medium or Low res but suggest you use same H.265/H.264 or PreRes422 if you have the space )
2. Enable Proxies in Pr when working on a sequence
3. Never import Ae projects, always convert them to a video and import the video
4. Under preference, Memory, set to “Performance” (this doesn’t make much difference especially with 64GB or 256GB)
As far as your hardware, I wouldn’t consider that “sufficient”. Disk I/O performance is NOT the issue with Pr … I’ve used very fast M.2’s and SSDs and RAID no RAID … makes no difference so long as the I/O device can work at 300MB/s or better.
I have an AMD 5950X (16C/32T) and Titan RTX 24GB and Samsung EVO 980 Pro M.2’s … and Pr is still SLOW if you don’t use steps 1-4 above.
One other thing is to enable CUDA (GPU Acceleration) rather than Software … when GPU acceleration works it’s much faster but be warned that some Effects might trigger render failures with GPU Acceleration enabled (my Boris FX Continuum does). You can also get the latest CUDA drivers here: https://developer.nvidia.com/cuda-downloads … but IMHO your 1030 is far too weak a GPU to do GPU Acceleration well, so I’d turn GPU Acceleration OFF or get a better GPU.
