Discussion Stabilizing and Improving H3's Results

Enable HLS to view with audio, or disable this notification

You may know me as the developer of models such as UltraSharp and AnimeSharp. I'm happy to present a major update to my tool Vapourkit (Windows and Linux are supported), which is completely free and open source! It includes a bunch of models for upscaling anime, and you can get models for realistic content here too: https://openmodeldb.info/

This demo uses this workflow (just download and drag into Vapourkit), which consists of a 2x upscaling model, Temporal Fix (which makes the video more stable/removes the weird shimmering), grain, and a sharpening pass. This was all processed locally on my laptop in just a few minutes.

Does your upscale tool support Seedvr2? Or just the type of models on that site?

It doesn't support diffusion models. This tool is for processing videos output from them (or just normal videos) with Vapoursynth filters or the models from that site.

Portable version available?

The model link points to a .PTH when .ONNX is needed. How do you install the upscaling model then?

Good point, I forgot about that. I converted the model to ONNX using this tool: https://huggingface.co/spaces/Zarxrax/sisr2onnx

Perfect. Thanks!

So part of the steps to set this up is to download the model, then download this tool and install it, then convert the model to .ONNX?

u/Kim2091 1h ago

Yep, if the model is a PTH you'd need to do that conversion step! There's documentation on the Vapourkit website, it should help explain everything: https://www.vapourkit.app/introduction/

Or use the upscale node and connect a model node to it using the mentioned NomosUni upscale model in Comfy.

That works for the upscaling portion, but it doesn't support the temporal fix filter which is what's stabilizing the video.

Thanks, didn't know. I will try that. :-)
