left: input, right: output
I’ve tried all the models, all the settings, several codecs, and I even forced the color space to not be set to Automatic, using BT709 and Limited.
Nothing works. I recorded the video in OBS; I hope the color error is noticeable. I managed to create a Python script to modify the color and bring it closer to the original video input, but there must be a way to preserve the colors as much as possible.
I’ve also noticed that even in the pre-render within the tool, the color changes are already noticeable.
I’ve read old posts about this, and it seems to be a long-standing problem in Topaz. I hope someone can help me.
