You can see from the screenshots that there has been some improvement in the newer models at removing this artifact. I read a few posts from a year or so back that detailed some explanation as to why it happens. It is known to be related to the use of sharpening and denoising in the same process, and typically happens on flat colored or relatively flat colored images. Something of note is that this artifact only appears for me on this specific orange background for some reason. There are tons of other flat colored backgrounds in the video I am working with that have no issues.
My Artemis add noise and recover detail settings are at 0. If I add noise it starts to remove this pattern but even at Add Noise: 10 (Maximum) the pattern is still clear, and of course, it is counterintuitive, introducing more noise than was in the original video to begin with.
I don’t know a ton about all this, but detailed areas of the original video have a decent amount of noise, while the flat backgrounds have very little, maybe that’s normal, but it makes me think that Artemis Low Qualities’ process is too aggressive on these low-noise areas.
Is there a workaround for this issue?
Is progress still being made on this issue?
For reference, here’s a mediainfo text file of the video I am working with. I’ll provide the video itself as well if necessary. Example.txt (1.8 KB)
Are you seeing this same pattern when using the medium-quality models or only with the low quality?
Your logs show you are also being affected by the bug in v5.2.1 that reverts the AI Processor to Auto instead of using the GPU. This was patched in the newest update v5.2.2 to keep the user setting of the GPU for the AI Processor choice once set in the Preferences Panel>Processing.
Hi, the pattern only appears when using the Low-Quality Artemis models. I’m kind of torn because the low quality models in particular do the best job by far for my video despite the appearance of that pattern.
Thanks for letting me know about that AI Processor Bug. I was wondering why my renders would randomly change from minutes to hours long, lol! I’ll be sure to update.
Changing to Artemis MQ removes the checkerboard but the overall image quality is worse than the original. Setting recover detail to maximum reduces the strength of the checkerboard pattern but doesn’t entirely remove it.
Try running Artemis LQ and Nyx as a second enhancement using the manual parameters to help flatten that pattern out. This should help reduce that low noise that is getting brought out by Artemis and creating that pattern.
