Hello, I’d like to know what I can do to try and improve this U-Matic copy I have. Unfortunately, this is the only version I currently have access to, so a new digitization isn't possible. What bothers me most are the spots, the reddish tint, the excessive noise, and the lack of sharpness. I’d also like to try upscaling it to 2K; what do you recommend?
