You're misunderstanding - have you read the full article, or just what I quoted? It's not the BBC that are talking about "tipping points", rather the author of the article - the BBC and their Natural History Unit are an example of what they consider a "blue chip user", and one adopting 4k.The BBC's warning of a tipping point was met with what? The purchase of more HD cams.
Not quite sure I'm with you....? General proposals are to shoot and display 4k at progressive frame rates of 24,25, 30, 50 and 60fps - exactly the same as possible with current 1080p HD. If you want the filmic rendition of motion - set to 24fps, for fast action sports, set to 50/60fps.For fast action sports 1080p at 120 fps will be a lot sharper than 4K at 30 fps.
I saw the demonstration in London during the Olympics, and yes, it was mentioned that such as 8k may benefit from 120fps. (Though frankly, it looked pretty good even as shown.)When the 8K format was demonstrated at the 2012 Olympics it was generally agreed that the ultra high resolution magnified the strobing effect which was problematic even at 60 frames per second. 8k cameras at 120 frames per second were invented to combat the strobing problems.
(It's also worth noting that the proposed micro-P2 cards are not likely to be capable of the data rate needed for 120fps AVC-Intra 100 - 400Mbs.)
No - I meant 400Mbitssec, straight from the Panasonic press releases - albeit trying to interpret the small print.Except that MicroP2 is capable of 1560Mbps. Unless you meant 400MBps.
In other words, they seem to be guaranteeing performance for sustained write speeds of 200Mbs (class 200 at 30p) but NOT at 400Mbs (class 200 at 60p)The microP2 cards will guarantee data writing up to the class200 mode of AVC-ULTRA, the company’s newest compression system***. .............
***With the exception of 1080/60p/ 50p within class 200.
Firstly, temporal resolution and spatial resolution are two separate things - you make it sound as if it has to be a choice of one or the other, and that is not true. Playback rates for both 4k and 1080 currently have 60fps as the highest speed - same temporal resolution.Now history is repeating itself and we have variable frame rate ramping up to 120 frames per second for the sharpest possible images yet this camera is criticized for lacking a 4K mode even though the temporal resolution is much sharper than 4K.
Well, maybe, but I suspect that means announcements by NAB2014, and product you can buy another year at best after that. Which even more reinforces the thought that a 1080 only Varicam will really seem obsolete before it's even for sale! It raises the interesting possibility of it's replacement being announced before it even goes on sale!!! Unbelievable.Development will see almost its entire product line refreshed to the higher-resolution standard by NAB next year, Kunihko Miyagi, president of the company's imaging division, told The Hollywood Reporter.
“We are developing a 4K system -- a whole set of products -- to allow for affordable 4K production,” he said. “Everything we make in HD will be 4K.”
Planned products include shoulder-mounted broadcast cameras, production switchers and handheld camcorders, which will bow in 2014, he said.
It may be a mistake to simply regard Panasonic (or any large corporation) as a single simple entity. Or that even a division within a company is truly a single entity. Everybody has their own place, own interests, own agenda. Hence it doesn't surprise me to see a figure at the top making such a statement, especially when you read the introduction to the article: "Keen not to appear a Johnny-come-lately to the Ultra-HD party -- despite having no shipping 4K production products ....."That's an odd statement from Panasonic. Why buy an HD product now, when you can get a 4k product next year? If 4K is the future of high end video production, then the new Varicam will be obsolete by NAB 2014, replaced by a 4k model.
Flippant answer would have to be "at least 4x as many"! But it's not just squeezing photosites onto the chip, it's all the processing etc that goes with it - and what about recording codec? What about the datarate?It'd be interesting to see a 4K HPX250 or AC160. How many pixels will they need to squeeze into a 1/3" chip?
Well, there's this, first shown at CES earlier this year.It'd be interesting to see a 4K HPX250 or AC160.
Yes, but for what you describe the *playback* frame rate was always 60fps. (Had to be, was dictated by tape formats.) And whilst what you describe was indeed the case, it's not the same as recording and replaying one scene at 24fps (say) and the next scene at 60fps. You have to ALWAYS replay at 60fps and achieve the motion rendition effect with duplicated frames.From the beginning the 720p Varicam had variable frame rate projection capability and this feature was not limited to slow motion.
To project variable frame rates in a 60 fps stream 20 fps is repeated 3 times 30 fps is repeated 2 times and 60 fps has no repeat frames.
But who's talking about a 4k camera maxing out at 30fps? The F55 for one is perfectly capable of 60fps at 4k, and I, for one, hope 4k at 60p becomes the new norm.Now if on the fly variable frame rate ramping up to 120 fps was offered in a 1080p camera costing $4000 would not this be more future proof than a 4K camera that maxes out at 30 fps?
"Sharpest highest resolution movie ever produced"? Yet in 2k? Overall that is simply not true, it can not be higher resolution than anything shot 4k. You previously said yourself: "....if you have inadequate temporal resolution you end up with motion blur...." and I don't disagree with that as far as it goes. But motion blur will only occur with motion, yes? What about relatively static scenes? Surely they must be sharper in 4k than 2k, regardless of framerate?Doug Trumbulls movie will go down in history as the sharpest highest resolution movie ever produced yet the naysayers insist that Doug's movie is not ultra high definition because it does not resolve 4K.
- my emphasis in bold. Which puts a very different slant on it. He's experimenting with 120fps - but only too keen to link it with 4k when the technology has evolved enough. He's not saying "forget about 4k, it'll be OK if you just go to 120fps" rather "I'm trialling 120fps now, and look forward to combining that technology with 4k".What I am exploring now is the highest possible current frame rate of 120, do it in 3D with dual cameras and dual projectors in 2K resolution—upgrading to 4K as the technology comes on line—.......
