NLEs should be able to stitch automatically after a quick update. A small plugin or something similar would do.
JVC releases affordable 4K acquisition/display solution

Not at all surprising. It's virtually the same camera JVC demoed at last year's CES (here).
The JVC PX10, which I believe is also based on FalconBrid, does 1080p60 H.264 at 36 Mbps, so quadrupling that (2160p60, or 3,840 x 2,160 at 60p) yields 144 Mbps. By the way, I believe that when Red says Scarlet-X will shoot 4K at up to 30fps, they are referring to what they call "4K HD," which is Quad HD (3,840 x 2,160 -- what JVC calls "4K2K").
Don't bet on it - I was an early adopter of the JVC100 when it came out, and it took nearly a year - and 3 separate programs - to get an effective workflow. It made a very pretty picture (for the time period), but I vowed never to rely on JVC's promises of editing systems catching up quick.
Still, since then, people have been dealing with RED work flow in a similar manner, so I suppose it's possible - but I wouldn't count on being able to cut anything meaning with it for a while.

I cannot wait till NAB.
The Scarlet shoots RAW, ... apples and Oranges.

Is this the 4SD card contraption? I dunno about you guys, but shooting to two cards at once would be scary enough, let alone four. I can just imagine the horror stories to come.
On the bright side if only one card craps out on you, you only lose 1/4 of your footage lol!

I smell lot of compromises in this technology.
But it is a step in the right direction!

I've seen this at a JVC Tech Showcase in London.
If I understood correctly it records to four standard SDHC/SDXC type cards simultaneously. Essentially, it splits the image into quarters and encodes each at HD resolution using four separate H.264 encoders. To re-assemble this video into 4K, you have to run it through a software application on your computer. The camera itself has four HDMI outputs, one for each quarter presumably. Remember - this was a prototype so all of this could change!
I saw some footage that was being played back from the camera. For the demo, each of the four HDMI outputs was plugged into an expensive-looking box of tricks that re-assembled the quarters into a single, 4K image, which was beamed onto a 100" screen by one of JVC's amazing 4K projectors.
Quality? Well, it was definitely 4K. It had that "looking through a window" feel to it. Pretty sharp, with good - if slightly over-saturated - colours. Of course you could tell that the lens hadn't cost $70,000 by a slight vignetting and chromatic aberration at the extremes, but, as JVC told me, the point of this camera is to give you a 4K look at a very minimal cost. You can imagine it being used for in-car shots, and other dangerous or inaccessible situations where you can treat a camera like this almost as disposable.
Overall I was very impressed, both with the tech resourcefulness, and with the pictures.

reminds me of another camera JVC got it's feet wet with. Let's hope this new one is a 'lil more usable

Ironically, without this camera, we wouldn't be where we are now. This was the first HDV camera, was it not? And people did use it.

Humph. It's 3,840 x 2,160. That's QuadHD. For it to be 4k, it would have to be 4096 x 2304. What is it with these corps that can't tell the difference between 4x and 4k? If they are lying in the very name of the camera (and yes, that's just flat out lying!), what else are they lying about?
And no, I'm not overreacting. I'm just sayin' that the emperor be nekkid.

Because it's not just one resolution that is 4k, check this:
http://en.wikipedia.org/wiki/4K_resolution
The entry does make the same argument of if QFHD should be considered 4k, but nevertheless, it is. I mean, look at the Digital film standards. Academy 4K is 3656 pixel wide, that's less than the QFHD.
I don't think it's lying, I think it's a question of accepted nomenclature.
What I think is annoying is here we went from 1080/720 describing vertical resolution to 4k describing horizontal resolution.

It was pre-HDV. It came out before there was anything called HDV. It didn't have an HDV badge on it, because there wasn't any HDV. When Sony introduced the HDV label with the FX1, they jointly announced it with JVC (even though there really was no overlap at all, the Sony was 1080 only and the JVC was 720 only and neither was compatible with the other). After that announcement, JVCs carried the HDV label, but the HD1 never did.
Not very many. It was 30p-only, and didn't really catch on. It was innovative, and the first consumer HD camcorder, but it never really made a splash, at least among the filmmaking crowd.

Definitely annoying. That's been the root of people thinking that "2K" is twice as high resolution as "1080p" even though, in reality, they're pretty much the same...

Petr Jackson used it in New York and thats enough for me :happy:

'cause 2K is 4K's midway, a subsidiary format when DCI dedided to start to mention it in their press releases:
http://www.dcimovies.com/press/06-23-03.pdf
http://www.dcimovies.com/press/09-24-03.pdf
Remember that DCI is a joint venture of hollywood majors, too far away of the SMPTE, ATSC Standards or Grand Alliance territoire, everyone coming from the television ground.
EDIT -- The (most) fun(ny) is when filmmakers started to use high definition video rather than film. I said it so, eleven years ago in 2001 during an HDCAM workshop at Lisbon Film School. It bothered people ;-)
