Since there weren't any complete 4K movie packages available for The Witcher, I decided to make one myself.
There are other movie upscale projects for The Witcher, but none are 'complete' and most use bad AI models that lose all sharpness and detail in the process. This mod aims to create a 'definitive' version for all cutscenes, cards and movies in 4K resolution.
