This shit is going to be a clusterfuck. People are still content with 1080p blurays, if not still adopting to it. We are still selling a shit ton of DVDs for fucks sake. There are still thousands of pieces of content yet to receive a standard 1080p release. Joe Whoever barely understands that 1080p is HD. You think these studios can convince him to give a hell about something called 4k? And not before 8k comes a year later. The rerelease of more expensive old content in such a short time, in such a confusing package, requiring new TVs with 4k resolution only to be trumped by 8k TVs in such short time later, after the overall flatlining/slump of 3D sets and content, will be the death of physical media.
I'm all for them including the movie 4k/8k resolution in standard blurays, allowing it to be downscaled appropriately for 1080p sets, but attempting to rerelease everything in 4k/8k will just confuse the general market.
So, everyone talks about live action in this....what about animated movies and 2D/3D animated TV shows?
Can they be done in 4K?
Similarly to a blurry transfer, the original source film is at a higher resolution than 4k or even 8k sometimes. There is no need to re-render, just adapt the high quality original print to the format's resolution.
