Yeah, it's not really noticable. That's why I pointed it out, but you probably know every pixel of every frame with so much work put into it ;).
I just recently read about MPC+madVR (I followed this tutorial), was using VLC all the time before because it's so easy and plays nearly everything.
I wondered if you can use madVR to yield even better results for upscaling the GOUT as a source of the Despecialized?
