Why is Premiere Pro playback stuttering?

I understand that there are lots of factors to this situation and have been watching many vids to no avail. I have a brand new comp with this hardware.

AMD Ryzen Threadripper 3970X 32-Core Processor 3.70 GHz

64.0 GB (63.9 GB usable) Crucial DDR4 -3200 CL22

AMD Radeon RX 6800XT

MSI Creator TRX40 Motherboard

Samsung 860 1TB M.2 SSD in Raid

The preview window always seem to be less smooth than on my older slower comp, playback stutters horribly when using 4k vids, and for some reason Premiere decides to just use 4% of its processing power when rendering. Sometime if I shut the program down and reboot it then it will at least use 22% of the CPU power.

Is this a codec issue? Bios? Settings? Any help or suggestions would be appreciated.

For me, on my windows machine and two macbooks, I've had MAJOR issues on Premiere when editing 4k footage that is10 bit, 4:2:2. If I had to guess, that's probably what your footage is too. Adobe has no answers. And I'm laughing at the person who suggested that your machine just can't handle 4k footage and to use proxies.

Hi exclusivemoose,

Sorry for your issues. 4K 4:2:2 10-bit is not supported on many computers. Take a look at the following article: https://www.pugetsystems.com/labs/articles/What-H-264-and-H-265-Hardware-Decoding-is-Supported-in-Premiere-Pro-2120/

It appears that if you don't have 11th or 12th gen Intel CPUs, it is simply not supported.

And I'm laughing at the person who suggested that your machine just can't handle 4k footage and to use proxies.

The AMD machine has no Quick Sync or NVIDIA GPU decoding so UHD H.264 or HEVC might be more troublesome. I think that transcoding to broadcast codecs or creating proxies is definitely worth looking at.

Cheers,
Kevin
