I’m encountering an issue with Proteus v4. It has trouble with dark areas, creating strange artifacts and green/purple smoothing effects that look really weird. I discussed this with someone previously, but it persists; it’s been a thing since 5.0.0 at the latest and might have been since the creation of Proteus v4. I have tried everything that I can possibly think of to fix this. I’ve tried every codec, I’ve tried rendering with 8, 16, and 32-bit float in After Effects, and I’ve tried adding a black square in the corner because when I emailed support once, someone said something about the video not having a true black value, which might have been the issue. The only thing that fixes it is just not using Proteus v4. Also, I do recognize the settings are very extreme, but it is happening even when they aren’t extreme; it also doesn’t happen with Proteus v3 nor any other version of Proteus, which means it’s a bug, I presume.

Proteus 4 has shown some situations where it reads the dark areas and black values differently than previous versions of the model. The team is taking these examples and information into consideration with training going forward and changes into the color space of the app in general.
Update
After running some tests and reviewing the settings you are running via the logs, this looks to be coming from the settings being cranked up as you mentioned. In tests with the settings lower the color artifacts were not seen in the hair or the black square you placed in the top corner.
I understand that lowering the settings reduces the color artifacts, but I need to use the higher settings for my workflow. Since these settings are necessary, is there any workaround or something to mitigate the issue?
When the settings are that high the model is pulling information out of the pixels which is resulting in the artifacts and color shifts you are seeing. Basically the model is working harder and creating new info, lowering the settings keeps it from going too far and distorting.
You can try lowering the settings and running an export, then bringing the video back in for a second pass to see if that produces a result you are looking for without pushing the model too far. The other option is to use a previous version of Proteus instead.
I see, thank you my friend.
