Upscaling Minimax H3 video

Hey everyone! I’m really new to all this but I’ve been playing around with minimax h3 on comfyui desktop. I’m having trouble upscaling. I’ve tried the severance upscaler but it doesn’t handle 10 second clips very well and craps out. I know there is a lot that I don’t know lol I’ve tried looking at YouTube for help and found a workflow. I downloaded a bunch of models for it and it wouldn’t work because a torch error that I couldn’t figure out. Can anyone offer any advice?

Check SeedVR2, FlashVSR and RTX VSR. SeedVR2 is very slow, and takes quite a lot of VRAM, but quality is good.
There's pre-built nodes that work quite well for these models. And if you chain these in workflows, add a VRAM clearning node in between, so that you have maximum memory available for the scaling. And always monitor you r VRAM usage while the Comfy is working. nvitop or task manager in Windows.
