Restoration tips: Overlap matching

Yes, resizer

Usually upscale using sincresize, because it's fast and quite good - still not perfect, as there is no perfect resizer (yet); downscale using lanczos or spline 36/64.

But for better upscale, I'd go with nnedi3 for upsize power of 2, then downsize using lanczos or spline 36/64, but often it takes so much time that's prohibitive...

I tested Super Resolution, that is better with lower resolution sources, but often only marginally.

I think a proper thread about the topic would be interesting, to gather knowledge and share opinions and experiences. And you, what do you use/prefer?

[nightstalkerpoet]

For this, I'd probably use NNEDI3 to upscale, though with your PanUp I'd use EEDI2 to only double height.

For downscale I prefer bicubic sharp (-1.00).

Hi, what program do you recommend to do the overlay in a video? I need to cover the whole left side .. sorry for the bad english ..

I'm an old dinosaur, and still using avisynth; probably, any half-decent video editor would be able to do that, though.
