Hi Selur,
I’m dealing with a low-quality DVD source, and I’ve run into a couple of issues during encoding that I’m not sure how to properly address.
One problem is a sort of rainbow-like shimmering / color fringing, especially around edges and fine lines. It becomes quite noticeable in motion, where the colors seem to flicker slightly.
Another issue is that very close line details tend to “merge” together. Instead of seeing distinct lines, they often get compressed into a single blocky shape, likely due to the limited resolution and chroma subsampling of the source.
I’m trying to improve the overall clarity without overly blurring the image. Are there any recommended filters or workflows to better preserve (or recover) fine line detail in this kind of situation?
Also, I was wondering if there are any AI / machine learning-based tools that could help reconstruct or refine line art — for example, separating merged lines or improving edge definition.
Any advice or suggestions would be greatly appreciated. Thanks in advance!

PS: I’ve managed to significantly reduce the issue, mainly thanks to Decross, but it still persists in certain scenes.
