Severe Blocking Compression Artifacts

[simple_simon]

I have a dvd source that has a few scenes of fast moving computer generated effects that have severe blocking artifacts. I've tried several different deblocking filters (Deblock_QED, vsDeblockPP7, smoothd2....), tried smoothing filters and even tried running it through QTGMC but nothing removes it completely. What's the best way to deal with this? Or is there an AI model that can work for this? I've searched but can't find anything that's specifically trained for deblocking.

Oyster_Deblocking
Oyster_Deringing (sometimes the better solution)
Oyster_Destaircase (for completeness sake)
Source has to be progressive and 32bit and no subsampling.
I can suggest to pad 64 pixels before and crop after.

I hadn't heard of any of those. Thanks. I'll play around with it.

DPIR Deblocking (https://github.com/Asd-g/avs-mlrt/blob/main/scripts/mlrt_DPIR.avsi) (comes with avs-mlrt) might also work.
