Scunet Strength

[Selur]

Overwriting the scan type to 'progressive', I see no combing. => the clip does not seem interlaced (thus the input scan type should be overwritten to progressive).
Whatever you used for the cutting of the clip flagged it was having 85720 frames.

Do you plan to change the brightness of the clip?

Just to see potential artifacts I used Retinex and moved it to the end of the filter queue.
This showed me something like:

Since the brighter areas seemed fine, I used a LimitMask with Limit 60 and 'invert' enabled, to only filter pixels with a luma value of 60 or below.
This then showed:

disabling 'Retinex' I got:

Sadly, the 60 limit basically disabled SCUNet for most of the second scene.
So I got another idea, maybe not limit SCUNet at all but apply CAS before it.

I followed the procedure you mentioned, but I couldn't find where to use the mask

If enable the 'Masked Controls' ( "Filtering->Vapousynth->UI->Show 'Masked' Controls" ), next to the filter there are now more options.
Here's a screenshot of what you could see (if you scrolled to the right or enlarged you Hybrid window).

Since these are quite a few controls most users do not use, they are hidden by default.
