4K HDR Content Rolling Out on iTunes Ahead of Apple TV 4K Launch

It was very nice of Apple to upscale all of my existing purchases. :)

The difference is so negligible it doesn’t matter. The now defunct h.264 format was nearly indistinguishable from Blu-ray. The new h.265 codec should be identical to the UHD codec. A lot of the streaming issues in the display of 1080P format on iTunes was the AppleTV not the file itself.

There so much incorrect information here that it's useless to even bother trying to unpack it all...

Disney and his pal, Mickey, are known to be thugs and want more money for 4k contents. Bunch of 240p looking fools....that means you, mickey!

It will be interesting to see if Google Play, Vudu, and Amazon match Apple with free upgrades to 4K.

I do not use discs. I watch content digitally. 4K digitally will still be better than 1080p digitally.

Discs are digital. 4K discs will be better than 4K streaming.

Not true, 1080P streaming was the same as the Blu-ray counterpart. 4K shows on Netflix were the same as the UHD counterpart as well. I’d assume Apple’s h.265 codec will be able to handle it as well. The flags are there but I don’t believe the files are available.

1080p streaming cannot compare to 1080p Blu-ray, and 4K streaming cannot compare to UltraHD Blu-ray.

What is the file size on the 4K movies?

Around 100GB. Lol

Excited by this. Having very recently purchased a 65” TV, together with many titles bought from iTunes in HD over the years (many thanks in particularly to the ‘Movie of the Day’ app!), a 4K upscaling on those titles is great news indeed...

I'd love a list of app 4K titles. Right now it's a guessing game.

Apple is still updating (so the list hasn’t been stagnant), but they already have more 4K than VUDU, FandangoNow, and Amazon.
