Is it actually possible to upscale 480p to something resembling 1080p?

@poisondeathray: Not really concerned about the colors since I don't see how a color shift cout lead to these artifacts, but here's the whole script:

I used. I suspect that this is some NVIDIA driver issue.

I suspect that this is some NVIDIA driver issue.

Then why is model 0 only affected for you? I'd expect a driver issue to affect everything

[Selur]

No clue, might also be the Vapoursynth version somehow. I use R60RC1. Anything that comes to mind should cause issues on multiple fronts not just with BasicVSR++ and model=0. :/

It looks too good.
Is it your personal sample or some from public, can you post original UHD for comparison? How long it took to generate one frame?

Original source was some "random" UHD video on this forum. Bicubic downsample to 720x480 .
https://forum.videohelp.com/threads/402943-The-quality-of-SONY-FDR-Ax700-lossless-NVEN...ith-Camlink-4K

But it wasn't a completely "random" choice - I chose one where there was fwd camera movement, to test the propogation and temporal SR aspects by using various intervals (or by trimming sections), and also one that had text/numbers because many machine learning algorithms fail miserably with text/numbers. And ideally one shot with a faster shutter to minimize motion blur. (There are other algorithms that reverse motion blur that you can test separately)

I didn't measure FPS (more like SPF ), but as mentioned earlier, it's very very slow. Larger interval sizes and more tiles make it slower too.

Man of course it was Truthlers video, don't know any other person lacking so many camera-usinf skills. Tho a lack of low shutter speed can be a good thing

What the heck is that stupid RGBS, it's been annoying me for over an hour

[Attachment 66633 - Click to enlarge]

RGBS is single precision float (32-bit) RGB

If the input is YUV, you have to specify the in matrix, e.g for "SD" or "601" you would use "170m"


c = core.ffms2.Source(r'video.mp4')
c = core.resize.Bicubic(c, format=vs.RGBS, matrix_in_s="170m")

Thank you, will try tomorrow

[rrats]

Starndard script doesn't seem to be doing anything the way I wrote it. Anyone knows why?

[Selur]

Judging by your screenshot, the issue is probably because you assign the output of BasicVSR to ret, but output c,....

ah i see. im new to the vapoursynth thanks for the help
