Just store it on it computer and viola, the content is magically 4K.For anything new, it's stored on the computer. All they have to do is re-output it to 4K. What's so hard about that? And I know how much bandwidth it will use... 4X at most.
I didn't mention old movies. Of course I know that upscaling to 4K is very difficult.
Try taking a 16x16 picture file then blow it up to 4 times its original size.
Doesn't it look great?
You obivously need to educate yourself about how a 1080p or even a 4K master is created.
They do not upconvert anything.
The original source(film or digital) is typically higher in resolution than 4K.
The studios must scan each frame of the original and downconvert it to a format(1080p, 4K) which we can watch at home. At the same time as they downconvert, they must attempt to retain all details.
This usually takes months to complete unless they don't care and let a machine DNR/scrub it to death, alter color timing just to get 4K content out quickly.
They will have to do this for anything they release for public consumption.
Just because content is new doesn't mean it's 4K or can magically be made 4K just because you have the HW.
THE SOURCE BEING USED/PLAYED MUST BE 4K IN RESOLUTION.
Otherwise, you are just upconverting.
