This repository is an example of implementation FidelityFX Super Resolution 1.0 (FSR) that port to WebGL.
Thanks to original porting that its in ShaderToy.

I thought that the technique could make static video source and streaming clearer, thus I tried to use for upscaling the image of <video> element on HTML.
So I wrote static video example and browser extension to test the result.
Here are some examples.

From these examples, I think that FSR 1.0 works well when the buffer resource to be denoised, no extreme small resolution and containing high spatial frequencies.
And it appears jagged a little bit on outline of Anime characters as in the picture.
