Show HN: fx-upscale – Metal-powered spatial video upscaling (github.com)

Hi! This is a quick lil CLI I've created for upscaling videos using Apple's MetalFX (https://developer.apple.com/documentation/metalfx). There are a few improvements I plan to make, such as HDR support and a progress bar, but if it sounds interesting, please give it a try and let me know what you think!
