The video is about an expensive HDMI cable that can improve image quality while upscaling.
The improvements are visible, but for something like Star Wars upscaling it’s pretty useless.
The various algorithms the processor in the cable is using are not exclusive to it (Anti Aliasing, etc.) . Also the cable is limited in what it can do because it has to do all these things “live” while not adding any noticeable input lag.
So all of this (and much more) can be done in the editing process as well.
Basically GOUT Upscales like Project Blu should already be much much better than anything this cable can do.
