Selur's Little Message Board

Does anyone use SeedVR2 ?
I know that it can be used through ComfyUI (leveraging ComfyUI-Manager and following SeedVR2 v2.5 Video Upscaling: Official Guide from the ComfyUI Integration Team | AInVFX Nov 7.

Haven't really tested this a lot, (I would probably need multiple faster gpus with lots of vram to really have fun with it) I'm wondering:
a. are there significant differences between the different SeedVR2 models?
b. what experiences do you have in regard to what prefiltering should be done before feeding a source to SeedVR2?
c. is it just me or does the 3b model somehow create somewhat strange/creepy skin?
d. is there

I tried the workflow SeedVR2 1080p-template available in ComfyUI (see attachment).

On my RTX5070Ti it was able to resize a small clip of size 640x504 to 1370x1080 at a speed of about 2.0 fps, using only the 16GB of VRAM (shared VRAM was not used).

Not too bad for a DiT model, but still slow.

Here a comparison between SeedVR2, Lancozs, RealEsrgasn_x2plus and BasicVSR++

SeedVR2 seems to provide sharper images respect to the other upscalers (I was unable to get "x4 ESRGAN" working on my side).

Strange works fine here (in Hybrid).

(note: SeedVSR2 has slightliy different resolution, since the PAR wasn't adjusted)

I think 'sharper' is the wrong term.
To me SeedVR2 does really sharpen more, but does add (invent) more details.

Does anyone know how to change the video encoding settings in ComfyUI ? (instead of crf23 I'd like to use lossless encoding 4:4:4)

Cu Selur

In this case RealESRGAN x4 to me seems better than SeedVSR2: https://imgsli.com/NDQ2ODk0

Are you sure that you posted the correct SeedVSR2.png picture ?

Dan

Yeah, pretty sure. (deleted the file but can re-create it later and check again)

Here's how the 1320x1080 version of suzie using seedvr2 looks like:[attachment=3487]

also checked the other version and the uploaded view is correct.

Any suggestion how to limit normal RAM (not VRAM) usage?
Wanted to filter some 1080p content, not really upscale, but I get: DefaultCPUAllocator: not enough memory: you tried to allocate 59719680000 bytes.

Ps.: just noticed my ComfyUI is 0.6 and current is 0.10 => updating now, maybe that fixes the issue

okay, seems to be an issue with the my source.
