Glitching frames

A long while ago, I posted to this forum because of a problem I was having where frames of my footage would randomly "glitch" and even render out in that glitchy state.

 

While my source footage is AVCHD format (and therefore actually H264 under the hood), I can confirm they aren't the result of corrupt files or an actual part of the footage - these glitched frames appear at different points in the sequence each time I open Premiere, do not appear in other programs and sometimes "fix themselves" after a while.

 

I have confirmed that turning off Mercury Playback Engine GPU Acceleration (CUDA) fixes the issue, but for a couple of reasons I would prefer to find a better solution that this. I can also confirm that the GPU Hardware itself is not at fault, as I tried other GPUs and the problem remained.

 

Back in my original post, I was filming in slow motion (120fps if I recall correctly, and in 1080p) which for reasons I won't get into I had sped back up to real time, and it was decided that this was an unusual "edge case" that Adobe . But I've now recently discovered that 4k 25fps footage filmed on the same camera has the same issue.

 

Even worse, the issue also occurs in Adobe After Effects and the glitches carry over both into Premiere when I import the project file and when I render out from that Premiere project, which makes it a lot more painful to work with when I want to use something like Content Aware Fill.

 

Is there any way i can fix this without disabling GPU Acceleration/CUDA?

 

I am using Premiere Pro version 24.0.3, After Effects version 24.0.3 and NVIDIA Studio Graphics driver 546.01. The camera in question is a somewhat dated JVC GY-HM200SP.

 

Here are my specs:
Ryzen 7 3700X
MSI Tomahawk X570 Motherboard

NVIDIA RTX 3070 (the issue also occured with two different RTX 2060 SUPER cards I borrowed for testing)
One SSD (Boot Drive & Adobe Installation)

Another SSD (for source footage, Media Cache and Preview Renders)
Seagate 2TB SATA 7200RPM HDD (for project files)

Whoops, made a Typo - here's the fixed paragraph with the missing part added in bold:

 

Back in my original post, I was filming in slow motion (120fps if I recall correctly, and in 1080p) which for reasons I won't get into I had sped back up to real time, and it was decided that this was an unusual "edge case" that wouldn't be worth Adobe's time to fix, so i would have to find some kind of workaround in the meantime and/or keep GPU Acceleration disabled.
