PhotographyBay posted that video showing the new SDXC UHS-I Speed Class 3 card. PB says it “will offer a minimum write speed of 30MB/s (equivalent to 240Mbps). Accordingly, the new Speed Class 3 cards will accommodate the rumored 4K 200Mbps .mp4 capture.”
Here is the video showing the card and the GH 4K:

Those cards must have a crash barrier inside to catch data moving that fast.
There’s a very small vat of treacle
Some of the UHS-I cards already write 70-80MB/s (e.g. SanDisks extreme pro) constantly, so what’s the deal?
That Panasonic can you sell their brand at inflated prices to those guys who buy everything from them.
“_minimum_ write speed of 30MB/s”
SanDisk Extreme Pro® SDXC™ UHS-I is MAX 90MB/s
Sandisk doesn’t give guaranteed min speed.
Those MB/s ratings are by the manufacturer and for maximum speed only, whereas the UHS Class rating is standardized and gives the _minimum_ speed. So your “45MB/s” card may seem like it beats a UHS 3 card, and maybe on the first run or two it will. However, after filling it, deleting a few pictures, etc it won’t deliver that performance anymore (unless maybe you reformat it).
If you don’t believe me, poke around for some benchmarks. Ones run on new cards will probably get near the advertised speed, but old ones will generally only get 10-20MB/s, just like you’d expect from their UHS Class 1 rating.
I was wondering about that too. I was also wonder if Vimeo or Youtube can handle 4k video? 😉 I wonder what the use for 4K will be, for the vast majority of us.
YouTube supports 4k. Here are some sample videos.

I guess you need a 4K monitor to appreciate it, because I don’t see anything special on mine.
There is something special, it’s a diaporama 🙂 My computer isn’t powerfull enough to play the video 🙁
More than that youtube will also support 4K 3D! If you got the PC muscle to handle that!

Says 4K but if you look at the frame size it is only 2K. The ad shot in NZ for the Sony handycam is closer to 4K. https://www.youtube.com/watch?v=hEYhkvZEVN4
Er, I’m currently using a Sony 16GB 94MB/s card (it was not expensive), and have cards from other manufacturers that are well over 30MB/s. Although there is currently no standard above U3, it has long since been exceeded. These cards aren’t even UHS-II.
OMG.. 4K and Panasonic (on top) logos are cheap stickers…. 🙁
So no real camera yet, just an idea…
OMG, what are you babbling about? If we re-branded it as a Leica, would that make you happy? Would the camera be any more of a camera? You are pathetic.
Wow….. is your butt aching? The other day I defended you but now I can understand the sucker you are. Get a life fanboy.
I woder if the 4k is just a Firmware update for the GH3?
No, the GH3 cannot do 4K. The displayed camera is just a placeholder for what will be the future 4K camera from Panasonic. Perhaps it will have the same form factor as the GH3, but it will not be identical.
Why are you so sure about that?
It makes more sense than teasing a firmware update by showing the camera with new labels on it would. Even if these labels are clearly just stickers as of right now, they imply something different than a future firmware update.
If we take in consideration that a Canon 50d was hardware wise able to shot raw wideo 5 years ago or the GH2 hacked could do some prety nifty stuff. I think the GH3 sensor and procesor are allso able to shot 4K.
So i think it’s the most cost efektive R&D decision to tweak the firmware and buy some 4k stickers and sell the GH3 as GH4. It can be they will just change the sensor caus the Sony sensor is geting old and they will put in thair own sensor from the GX7.
I dont think Panasonic will releas a firmware update.
Those idiots in SD association are at it again. One more meaningless logo on the card.
Why dont the all just stop paying membership fee an let them die.
OR, you can stop using them altogether, and don’t support it. Use Sony sticks or whatever instead.
UHS-II at 260mb/s is the next big step for SD cards. Toshiba is selling them today at very high prices. So we need other SD card manufacturers to help bring prices down and cameras to start supporting the higher speed. At this speed you will be able to shoot continuous RAW at 5+ fps with little to no memory buffer.
Maybe, but camera internal electronics needs to support UHS-II also. Will take some time to reach this market, smart phones / tablets are first I guess.
The internet is where the most media is consumed these days and therefore, at least in Germany, 4k is dead in the water.
The German Telekom will soon (2016) end offering flatrates, limiting monthly download volume to 75GB. Since the Telekom owns the entire backbone infrastructure, almost every major provider will have to cripple their flatrates as well. Loading 4k stuff under such circumstances is just impossible.
Um, no. There is a recent court ruling forbidding them to call it a “flat rate” plan if in fact isn’t. Also, this only applies to T-Online. They can’t force other ISPs to give up on flatrates, even if they own the infrastructure.
Well, it’s just a preliminary result. And you know how it works: in the end the big boys get what they want 90% of the time.
And yes they can. Otherwise no one would care as we could just migrate to other service providers. I believe there were some satellite based providers, so those wouldn’t be tied to such a decision but these also have a rather bad reputation (network instability).
If you enlarge the video full screen, you can clearly see that there is a sticker ‘4k’ put over de gh3 logo. You can clearly see the edges. Does this mean that this is not how the gh4k is going to look like?
Maybe there’s something about the GH4K Pana doesn’t want to show (now) until patent are in place etc.
It looks like the patent is already in place.

Yes, but a 4K version of the GH3 would only need a different sensor and processor board, you could keep the rest the same (err, except 1/8000 shutter pretty please). Also the field-test units definitely wouldn’t say GH4 on them, so adding a sticker for a show seems possible…
As far as I’m concerned it’s just down to whether they use all the pixels in the sensor to make the video image or just some of them (like all current m43 cameras, inc my GH3, alas) which gives moire issues which I get bitten by too often, even shooting flat… If it does I see one in my future 🙂 otherwise back to Canon I guess (the 5DmkIII, Cxxx series and the Sony RX10 are the only SLR-style cameras that avoid moire so far, fingers crossed!).
The Canon CXXX series are hardly ‘SLR-style cameras’.
Fair point, I was 50:50 on including them.
A GH3 with a 4K sticker and an SD card with a new stickered logo.
Panasonics label guy in the mailroom has been busy. The engineers haven’t.
Peaking on my GH3 please!
Since they spent so much effort on making the GH3 good at getting rid of heat it really wouldn’t surprise if they use that body for a 4K model…
Well Steve, this patent looks like it. I’ve been analysing the patent and comparing it with my gh3. It seems clearly that they completely removed all photo functions and optimised it fully for video. The flash is gone, the single and mutiple burst shooting is gone while the camera still looks very high end. This has to be the ‘gh4k’ im 90% sure.
There is no consumer cam with this much buttons.

Great find, I think you’re right!
These UHS-1 class 1 SD cards can match the max transfer speed.
http://www.toshiba.co.jp/p-media/wwsite/uhs.htm
But if the GH4 need to write to 200Mbit/s (25MB/s), then UHS-1 class 3 should be used.
UHS-1 class 1 can only guarantee min transfer speed to be 10MB/s.
UHS-3 class 3 min transfer speed is 30MB/s.
