I often see people bash the fact that UltraFlix has "upscaled" content. This is an older article that perfectly lays out the process that 4K Studios uses to process their movies. I would think it's even more fine-tuned now. Anyway, it's a good read with some good info from LX Rudis. They do a lot more than "upscale." Enjoy.
