i believe the 60fps @ 5.7mp is only for 2 1/2 seconds - let´s hope it´s got 720/120p....and if memory serves me well, it´s got a 2/3 sensor....at least that´s what the rumors were saying a couple of months ago - looks like all the specs are being translated from japanese so .....

well I stand corrected...it´s a 1/2.3 sensor ...and here´s the best info I´ve found

They are still jpeg images, so 144 frames will be a little over 2 seconds. However, the important thing isn't so much this camera but rather what it says about the upcoming 4k JVC camera and more importantly about the progress of image sensors in general.

What we know is that this sensor can output 3200×1800 images at 60 frames a second (though it may be limited by its frame buffer). The JVC 4K2K camera will output 3,820x2160 at 60 progressive frames. More importantly we are talking about affordable sensors that require little cooling. This GC-PX1 is in a fairly tight packaging, sensors operate at a certain clock speed, higher-end video cameras have larger heat-sinks and even peltier cooling to achieve higher frame rates and resolution. Comparatively this is a small sensor that has less surface area to dissipate heat and is in very small packaging with little luxury for airflow. While JVC is likely using an outsourced sensor (since its BSI) but its a harbinger for things to come.

Just as interesting JVC has the downstream LSI to support these next-generation sensors. The Falconbrid in this camera will encode 4K2K/60p at 144Mbps. We really are going to start seeing very fast and high resolution cameras hitting the market over the next year at affordable pricing.

That is if the camera makers (especially with their pro lines) let it happen! My guess is they will try to control the release rate as much as possible but Scarlet might force the issue.
 
Worth keeping in mind that on a 24p timeline, that will give 6 seconds of 3K slo-mo... usable, for certain shots.

Also, if it is like the Casio EX-F1, it will have the option to do 20/30fps (hopefully 24fps) for 144 frames too... making it even more useful.

Agree with Steve 100%... the 4K2K camera is gonna be much more powerful than this and should be really exciting.

scarlet ......so far that´s just a color ! If they don´t out in april ..... well sonys´s35 nex will be comin´round the bend by then for about the same dollars and red will have to compete with that sensor with a 2/3inch ....geez I dunno know , methinks sony will shake things up alot more than red or jvc

We're going to see a 4k2K JVC camera that will be relatively low in price this year. This affordable camera here has most of the required technology for that 4K camera and will be in production THIS month. Which is why I found it interesting.

As far as professional equipment, there is going to be clear difference in IQ that will justify the price difference. I don't think we'll see much holding back as most of these cameras will primarily be aimed at the consumer/prosumer side of the market. And the high-volume consumer end of the market is far too competitive to be holding back for fear of being left behind. The professional end of the market will likely need to move beyond these bullet-point spec-based marketing to more substantiated image quality improvements to sell their products. Which shouldn't be a problem.

Also, the dSLRs should get higher resolution video/high frame rate mode as well. This seems to be the trend that the camera manufacturers are gearing up towards. For instance, Sony's new SLT pellicle mirror system only really benefits high-speed photography and video (as it otherwise cuts 1/3rd of the light going to the sensor). Then there are all the mirrorless camera that has rejuvenated research in contrast-based AF. A lot of its going to be geared towards sports/photojournalism where the benefit will be about grabbing the perfect high-resolution frame off of a video stream for still photography purposes.
 
You are probably correct. I do not have any interest in a 4k consumer camera. Or for that matter, a 4k pro camera. I shoot video, not movies and all of that extra resolution is just extra resolution to me when delivery & backup come around.

From this pros perspective, I want to see the RAW processing. Resolution is a marketing tactic but high bitrates and RAW actually make your footage look better. This is where Scarlet will have its impact and hopefully for the big three + JVC to end this codec limitation war. I mean we are capturing HD at or close to DV datarates. Sure the codecs are more complex but when 2TB hard drives are under $100 and they have CF cards on the market that are 40MBps there is no excuse anymore.
 
Bit about the camera on dpreview in the news section, but just has a link to the same Japanese press release (nothing new). Might be interesting if you could shoot 24 fps for 144 frames (though that's still just 6 seconds worth).
 
CP+ Update:

JVC showed their prototype of their 4K2K consumer-level hybrid-camera (They've also showed a higher-end version previously). JVC also intends on having prosumer and professional cameras using this 4K2K Falconbrid LSI, and is looking beyond 4K.

the first to give me 720/120p will get my dough - it looks like the processor is capable if jvc sees the wisdom
 
I have no doubt this will emerge quiet well. The research of 4k broadcast in japan is more than 5 year now, and if im not wrong in 2007 they make the first test of live 4k broadcasting with 4k cameras and 4k signal.

This will make lot of sense if it goes right, and the benefits are very big for consumer market. i know HD is mainstream now, but rapid transition to 4k wont be a bad invesment in long term ( for technology stand point ). Afordable 4k solution is a must.

Be ready from Canon, they will deliver something similar, and maybe first in DSLR way, so they can finetune their camcorder deparment later. They are too big in DSLR market, and they know for shure that the changes they make have colateral effects. Making a 4k codec for DSLR to the mases will force the market to transition faster than you think.

Good work JVC +1
 
So, help me understand here...

This little JVC can shoot 4k video, once the exclusive realm of the RED? is that correct? And for the price of a consumer camera?
What is 4K2K exactly?
 
One wonders why they don't hire a professional cinematographer to shoot their samples...

instead we have a shitty shot of a kid smacking a warped baseball (not impressive at all - especially the color) and another shot that looks like stock footage of birds from a Hi-8 camcorder used in 90% of japanese language karaoke CD's...
 
And size of a chip is ...??

Not full 4K horizontally - only 3,7K but it has 2,1K vertically
 
I must say I just don't get it. Why would a consumer need a 4k video camera? We now have the megapixel marketing in video resolution. I can hear it now - "but can I put it on a DVD?"...

Meanwhile JVC professional has released basically the same camera for the last five years. It seems the consumer areas are the testing ground for what might make it to professional levels? Seems backwards.

4K2K is 3,840 x 2,160, basically quad-1080p; (1920*2)x(1080*2).

BTW, the BBC/NHK's 8K resolution is also 7,680 x 4,320, which is basically quad-4K2K, or 16x 1080p.

As you can tell they are all evenly divisible by 1080p. All future 4k TVs will be 4K2K because it makes sense to have this modularity in specification from a manufacturing point of view as well as scaling point of view. Though its popularity and availability of content will be questionable.

The fact is the consumer doesn't need 4K, but then again they don't need 18MP dSLRs when they are only going to be posting low-res pictures to Facebook.

But the consumer market is the testing ground for the professional market because with modern sensor technology volume matters, and you can't justify the massive investment for new technology if you are only selling several thousand units. In fact, a lot of new CMOS sensor technology is first being developed on cell phone sensor market; BSI, CMOS global-shutters, etc and then trickling down to lower volume markets due to reasons of economies of scale. Keep in mind, JVC is likely outsourcing their sensor development (BSI is a clue), there are very few companies that can build and design a sensor from the fab to the end user. ARRI for instance used Cypress Semi (now part of ON semiconductor) to design the Alexa.

The major point that we should be getting from this JVC cameras is that we should expect future cameras from different manufacturers to easily go beyond 4K even at the low-end. The fact that this camera starts off at 4K2K@60 fps right off the bat, instead of starting off at 24-30 fps, should be indicative of its future intentions (not to mention the Powerpoint slide).
