ML Denoise Artifact

Loving Denoiser ML / Regrain workflow, but I did just notice a big, fat artifact in my comp that comes on/off when I toggle Denoiser ML. Can I send a plate to be looked at by the team? Seems to be related to having an overbright area in Linear.


@dungeonbeach Can you clarify exactly what you are doing when you say you are toggling Denoiser on/off. Are you toggling the enable state with the D key? You can private message me 5 frames of the source clip. I will need that many to check the Denoiser. Thanks.

I have this exactly the same issue with the overbright/light area. Denoiser ML just puts a black square/hole over it… (Cant share the project/screenshots for this).
Exr’s in Aces2065-1 colorspace

Could you clarify if this happens for or both Model options in DenoiserML, or with “Compression+ Noise” only?

I can reproduce this with an EXR clip with over bright values. We will take a look at it. You can get around this for now by placing a Develop node before the Denoiser ML node and reduce the Exposure until the artifact goes away,. Then, place another Develop node after the Denoiser and do an inverse Exposure adjustment.

In my case, it happens with Camera Noise v1.0, and it is gone if I select Compression+Noise

Thank you. The team is now aware of this happening. Sorry you’ve hit this bug, and hopefully we’ll be able to fix it soon.
