Eventually, I hope to get around to creating proper 4K upscales of deleted scenes using Gigapixel AI, but in the mean time HAL9000 has the best upscales currently around.
I reached out to various people I know from all over the internet who performed various successful upscaling projects I know of. Basically, the plan is to accumulate some additional knowledge and maybe get to know some variants in technique.
Having deleted scenes indistinguishable from at least 1080p footage would be a really big help for various fan-edit projects out there.
