JVC Unveils Handheld 4K Camcorder

Can I just say that this excites the hell out of me for what JVC's got in store for it's ENG Form factor line!

If this camera puts out a good picture with that 1/2" chip and records f hours of ANYTHING even remotely like 4K but without RED's goddamn transcoding and to SDHC cards, many a video producer will overlook it's "Not-a-RED"-ness and jump for it, stimulating JVC to move forward on the ENG form factor. $5k is a little steep for such a tiny thing without an interchangeable lens mount but lets face it - this is the most badass testimonial-room/Wedding camera, to-date. The 4K monitoring, alone, makes it drop-kick a DSLR, even if they start making more DSLR's with HD monitoring. JVC is wise to have waited till the Canon/RED buzz had killed itself in November to release this bad-boy, now. And a scheduled release just ahead of NAB? Smart, smart, smart.

Had my eye on the HM700's series for a while. I think I'll wait for the... HM800? 2/3" chip maybe? HD-SDI monitoring, dual card recording? Maybe a DSLR lens mount or even PL mount? C'mon JVC, really blow us away...
 
I saw a blurb on this from last year's NAB. While the idea of 4K in such a compact HVX-style camera is pretty interesting, I'm not so sure about it. Mostly because it's JVC and with the chip wars going on I can't imagine that it would get that much play. The best thing I can hope for is that this pushes the other guys into 4K. If Sony came out with a 4K EX-3, then I'd be pretty excited.
 
For gods sake, are they that DUMB over there at JVC. All they needed to do was add a little bit bigger sensor and a lens mount. Thats it. SO CLOSE, BUT YET SO FAR. Oh well, i NEVER LIKED JVC ANYWAYS. I've always thought their prosumer cameras sucked.
 
A lens mount would mean no AF, no ENG style shooting and a smaller sensor means larger DOF. I'm fed up of 95 % of videos out of focus on large sensors cams...

Huh? There are many lens mount cameras with AF. Canon 5D, Sony NX series,etc. I agree with the large sensors are hard to keep in focus for some people, but not for the pros.
 
It's interesting. Who is this camera being marketed toward? Your end product ends up being 1080P Blu ray at best. It's not intended to have exchangeable lenses. Ton's of stuff is shot on compact HVX bodies. Not everything is large sensor/exchangeable lens gravy.

Also, I have a AF100. And sometimes a fixes lens with a servo zoom is actually the best camera for the job. Depending on what your shooting.

True enough in one narrowly defined category -- physical 'hard copy' delivery. But a remarkable number of the projects I've delivered in the last couple of years have never seen 'hard copy' -- some old-school government clients still have contracts that require a physical copy, and broadcasters ... but corporate clients are mostly accepting a file, on HDD or FTP. And that file may be any resolution or dimension, depending on their target. Need a 4k file for a tradeshow projection? Or a cinema pre-film advert? Or maybe just a high-rez file to future protect against next year's delivery method ...

Just sayin'. End products aren't what they used to be.

Cheers,

Doing for the first time the JVC 4K workflow in Premiere Pro (Windows 7 64 bits) (click for a larger picture) :


No conversion needed on PC to get a 4K stream.
Just put the 4 HD streams in the timeline. Set them at these positions :
SD1 960 540
SD2 2880 540
SD3 960 1620
SD4 2880 1620

Remember these numbers you'll use them all the time from now.

And you're done, it's PERFECTLY stitched. :p
Put them in a nest if you want.

It renders and plays at realtime @60p on my i7 PC.

A quick color grading "CSI Las Vegas" :

Very cool Jaspion! Did you have to use a special plugin from JVC to do the stitching in PP. Any chance you could post a 4K frame? Thanks for sharing..

No special plugin for stitching. But I think a script could be easily done to automate this.

4K frame (jpeg compression - click for larger picture) :



It's quite impressive to see this running at full resolution @60 fps without a "RED Rocket". ;)

Is that larger picture heavily compressed? There's zero detail in any of the leaves and on the rocks. Can you provide an uncompressed version?
 
Looks more like not enough bitrate for that type of compression. Either needs higher bitrate or different compression implementation
