If i'm not mistaken, for a feature film to be screened at cinemas - the final output is normally scanned to 2k or 4k...I guess Toshiba has probably reached that resolution.

With resolution 2k and above, one would really need a really2 huge screen to really justify technology. Not sure if its an overkill for normal household usage. But hey, the more the merrier eh? tongue.gif

The screen must be big or relatively people must sit closer to see the benefit. Even on 50" each pixel is no bigger than the tip of a pen. They have to make it big, which means more expensive and only elites with big houses can only consider.

About physical discs, it is reported that a quad-layered BD has already been produced, only not available commercially yet. It can hold 100GB of data. I think I've read somewhere that blu-ray can have even more layers than 4.

35mm analogue films can be scanned at 2160p, in fact many high profile blockbuster films already been scanned at that resolution (they're then downscaled to 1080p for blu-ray discs). If 70mm film was used to shoot the film, it can even be scanned at 4320p, which is exactly what they've done for Baraka.

Many movies are now shot on digital HD camera at 1080p only. They will be in trouble because the master source is only 1080p, they will have to be upscaled whenever blu-ray starts to support 2160p. However, RED Cameras (their 1080p/24 RED ONE was used to shoot Knowing, Zodiac, Benjamin Button, etc) has already developed a 2160p capabled camera.

So, I think 2160p is really not too far away. The only question, can everyone afford a big house?

Red camera is capable to shoot in either 2k or 4k...shooting in 4k has its benefits coz we can really blow up certain shots and manipulate the camera work for better cinematography purpose. However for 4k, the post production is quite a nightmare since the files are freakin huge! A few local films have been shot on Red - even KRU's latest epic were shot with that camera - but still, whatever camera one used, if the story sucks - nothing can save it...hehe.

Normal feature films shot in HD are normally scanned just to 2k resolution only...mainly due to cost and time factor in handling digital video files of large quantities.

some of us are still in awe with the picture quality and details from BD, and to some extent i personally hate the too-digital-artificial feel of certain BD films, the soul and analog celluloid feel of film is gone to some extent if all things are too much digitised...

so I guess 2k is just too much now for us laymen...lucky i'm still content with my 720p hd65 tongue.gif

Note: Early next year a local film about girls in skirts will be released entitled 'Hooperz'. This film was shot on RED camera, in mixture of both 2k and 4k resolution, and now it's in Dolby Digital audio mixing stage...hope it'd be a film of audio and visual feast for the masses. tongue.gif

HD resolution is one confused topics. I guess 2k is probably just a higher than 1080p. Common confusion about HD home video format vs digital cinema formats, explained here:

"And, to throw a total monkey wrench into the understanding: video formats are referred to by their VERTICAL (y-axis) resolution, whereas the 2K/3K/4K digital cinema formats are referred to by their HORIZONTAL resolution.

So, in video, you'll hear about 480i, 480p, 720p, 1080p, and 1080i. Those correspond, of course, to:
480i/480p: 720 x 480
720p: 1280x720
1080p/i: 1920 x 1080

But, in the digital cinema notations of 2K/3K/4K, it's talking about the horizontal (x-axis) res. So:

2K = 2048 wide (2 x 1024, 1024 = 1K) so it's 2048 x 1152.
3K = 3072 wide (3 x 1024) for 3072 x 1728
4K = 4096 wide (4 x 1024) for 4096 x 2304.

Using these numbers, we can see that 2K is only slightly bigger than 1080P, even though "2K" (2048) sounds like a lot more than 1080, right? It's because the 2K refers to the horizontal, whereas the 1080P refers to the vertical. But once you do the math, you find it's 2048x1152, vs. 1920x1080. So 2K is about 14% larger than 1080P.

On the other hand, people sometimes think that 4K is twice the res of 2K, when in fact it's 4x as much. 4K is twice as many horizontal pixels, and it's also twice as many vertical, so you could fit four full 2K frames inside one 4K frame."

hope this article makes sense tongue.gif


I guess those in Hollywood don't really go for the Red camera mainly because it is still new, albeit it's now more common there for the indies community since its cheap...

The major studios with big budgets should still prefer to either shoot in 35mm, then scanned for DI the kine back to 35mm (in 2k or 4k) for analog theatre distribution, or shoot in the more stable hi-end digital HD cameras like the Sony Cine-Alta or Panasonic Varicam or Genesis, then kine to 35mm for distribution, or retained in digital form for digital cinema projection.

back to topic - 2160p??? bring on the pixels baby!
