UPDATE 2.0: I had some issues with the original workflow, wich for some reason is running on CPU on the last versions of ComfyUI. Switched to Comfyroll's upscale custom node, wich also made the workflow even more simple.

Hi everyone! i recently needed to upscale some videos, so i extracted the nodes wich make the upscaling from ipiv's Morph (https://civarchive.com/models/372584/ipivs-morph-img2vid-animatediff-lcm-hyper-sd) and i put them in a standalone workflow.

I'm posting that here, just in case it can be useful to somebody.

You can use any ESRGAN-like image upscale model, for example https://civarchive.com/models/147641/nmkd-siax-cx
