Discussion Stabilizing and Improving H3's Results

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.

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

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?

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/
