Topic # 113202 9-Jan-2013 13:32 Send private message

I have started this thread to discuss the new standards 4K and 8K as they relate to home and commerical theatre in NZ. 

Does anyone know how many movies recorded in the last 10 years are 4K or 8K natively or if based on the new standard, only new movies recorded with Sony RED cameras or similar can produce the resolution required?

Saw the 84" LG 4K TV at Harvey Norman yesterday. Amazing picture.

Because it is a higher frame rate more frames have to be shot per second, hence you need to set out to make a 48FPS flick using the right equipment to start with. Much like a proper 3D film.
You could upscale a pic to 48FPS, but that would most likely be even uglier than a 3D conversion (like Clash of the Titans).
CG animated films could be turned into 48FPS more easily (see the 3D version of Toy Story), just by inserting an extra frame inbetween each existing one. Hand animated films would require twice the work; stop-motion, even more so.

Youtube has support 4K for about a year now. Not sure about 8K but I think you will have bandwidth issues long before Youtube can keep up.

I believe the hobbit was shot in 5k http://www.fcp.co/red/44-red-cameras/99-the-hobbit-to-be-filmed-on-reds-new-epic-camera
But wouldn't older film stock be able to be converted to 4k or 8k, unlike digital filming, which has a fixed resolution. That is one of the benefits of film, as some older tv shows in the 40's-70's shot on film were able to be converted to full 1080 HD, while newer shows shot on video stock in the 70's, 80's and 90's are only in SD and can't be upscaled, and are very poor quality.

Old film stock could be rescanned at higher resolutions, but not at higher frame rates. So 4K yes, 48fps no.

Which HN was that? I would like to see it in person!

And does anyone know if the Sony 4K TV that comes with a 4K player (on 'loan' from what I understand) is available in NZ?  There may be an increase in 4K stuff, but I cannot see much of it coming to NZ (happy to be proved wrong).

I wonder if TVNZ/Sky have any firm plans on upgrade paths? Anyone in the industry know anything?

And with CES going at the moment, there are LOTS of 4K displays being shown.  Apparently the 4K OLED displays are stunning.  Some stuff via Engadget:
3D 4K TV
Make a PC and 4HD displays into a 4K display

I think it was LG who said that once you get to 8K you don't even need to implement 3d as the picture looks so real anyway.

The only camera I could afford with 4K is the GoPro Black edition, but it only shoots at 14 FPS in 4K. Does anyone with a bit more film knowledge know what that would be useful for (if anything?).

would a 4k movie fit onto a bluray? or will there be a new format coming out for 4k movies?

i would think streaming a 4k movie would be a huge amount of data

They could always use some software to approximate the inbetween frames, like motionflow tvs do. Technology in that area is improving.

Blurry standard allows for up to 8 25GB layers, so there would be room. Although i imagine you would need a new player etc. I could imagine the read speed of a blu ray drive may not keep up if it was so many layers?

Lol considering 80% of Sky isn't barely in SD yet, I'd be somewhat surprised if it will be along any time soon! I am not sure how much bandwidth sky has for broadcasting, but I imagine it would require a lot more.

There's a new video codec (I've forgotten the name of it) that can supposedly do 2k in half the bitrate of H.264. Extrapolating that, if you can currently store a 2k movie in 30 GB using the existing codec then you'd be able to store a 4k movie in 60 GB with the new codec. So just add another layer (probably two for future-proofing) and you're set.

In any case you'll still need a new player.
