The recently launched Samsung Galaxy Note 3 phablet is powered by a Qualcomm Snapdragon 800 processor. Equipped with this chip, the Galaxy Note 3 is bestowed with the capability to record 4K videos with 3840 x 2160 resolution or four times larger than Full HD (1920 x 1080). Snapdragon 800’s capability to capture 4K videos was demonstrated at a workshop held in Beijing last July. Yesterday at an exclusive event held in Dusit Thani hotel (Makati), the folks at Samsung Philippines gave us a chance to play around with some units of the Galaxy Note 3 phablet. There, recorded a 4K video by using the device. We have uploaded the video on YouTube (above).

Below are the specifications of the video based on Media Player Classic:

Type: MP4
Size: 123MB
Time: 21 seconds
Resolution: 3840 x 2160
Video format: MPEG4 Video (H264)
Audio format: AAC 48000Hz stereo 1536Kbps

For those who want to watch and verify the specifications of the video uploaded, you may download the actual file here.

Why you simply just dont make framegrab in native 4K resolution in VLC player?
You can download 4K footage via keepvid.com service.
 
twice horizontally, twice vertically, four times in area, or in number of total pixels
still unnecessary if you ask me

What kind of math are you using? 3840 is more like TWO (2) times the size of HD, NOT 4.

I think the particular kind of math being used is commonly referred to as "correct math". lol. :P The fault in your math is that you're only multiplying in one direction, which is faulty math, similar what I've experience when talking about front projection vs HDTV screen sizes. For some reason when I've mentioned a 100" projected screen vs a 50" HDTV people seem to usually think the 100" is only twice the size of the 50", but it's actually quadruple the size. It's only twice the size in diagonal length, but it's actually the exact size of four 50" screens, hence four times the size...not two times. You always have to remember to multiple in both directions in cases like this or the math will be wrong. :)
 
As I was watching that video I was saying to myself......"not sure what city this is shot in but sure looks a lot like Toronto".......a few seconds later a TTC Bus goes rolling by and it is Toronto....but I digress.

That video looks pretty darn good for a phone

It doesn't handle highlights that well but I set up YouTube to show the original file size and I was very impressed with the detail and sharpness of the video. It's pretty amazing to be able to shoot that kind of video on your phone.
 
The Note 3 is one of the first phones capable of shooting 4K video, with a resolution of 3840 x 2160. This is a huge resolution jump over standard full HD video: an HD video frame is 2 megapixels, while a 4K frame is more than 8 megapixels.
At the moment, very few people have 4K-capable TVs or computer screens, so this feature is probably more interesting as “future proofing” than anything else (you may also have trouble playing it back, even at normal HD resolution, on older hardware because the processing demands are substantial). You can already upload and view 4K content to YouTube, but the compression takes a big bite out of quality as usual. The frame grabs below give a better sense of how much more visual information 4K video carries.

The Note 3 caps 4K recordings at five minutes, and digital video stabilization isn’t an option at the higher resolution (we didn’t see much evidence of it working at normal HD resolutions anyway).

Hahahaha my phone outperforms BMCC in terms of sharpness, aliasing and moire:):):)
Interesting times...
 
Interesting stuff here. The Samsung image is pretty good. Looks like 4K is going to be forced down the consumers throats. It's the only way to get those TV's in your home.

Definitely, yes. With this kind of manoeuvres consumers will get used to the term 4k. But besides that, 4k is primarily a selling point for this phone as it's supposed to be top of the top as I understand it.
 
One thing I noticed was that the stabilisation of the HD is gone when shooting 4K. You need it…badly. Without it, the footage is so shaky it’s pretty unusable and we aren’t talking handheld movement, it’s incredibly sensitive and with its CMOS sensor the rolling shutter artefacts are very pronounced. I shot everything with it resting on my screwed up fleece. Even then just breathing and holding onto it (so it wouldn’t fall into the river!) gave me some of that movement. It also needs good light. You can see in some of the shots the noise. It really struggled. It normal daylight it would be fine.You could use the 4K mode to scale down and give you exceptional HD…the problem is the shakiness of the footage due to the loss of image stabilisation is a price you would have to pay. Handheld use is essentially out.
Then again it is a mobile phone that shoots 4K, so what do you expect? 14 stops of dynamic range? 240 FPS? XLR inputs? Perhaps even raw?!? It’s a damn damn fine phone indeed, and the camera is pretty nice as is the normal video. Very video-y but that’s what I expected….what if though…? Maybe ARRI would do a deal with a mobile phone company like BEATS audio did with HTC…the HTC ALEXA! Can you imagine it? A mobile phone in your pocket with a Super 35mm sensor, 14 stops of dynamic range and records ProRes 444 or ARRI raw! Well we can dream, right? Think of that amazing filmic quality we could use for our 6 second Vines!!!

Despite all its issues, it’s a pretty nice looking image. It’s contrasty for sure, too sharp and saturated…a bit like the Canon standard picture profile. Perhaps there is a way to dial all that down? I couldn’t find anything. There are also the usual image pattens of aliasing and moire.
For me though, I think the single biggest issue with this 4K feature is one thing. Its codec. It’s TOO WEAK!! When I put together my edit, I could not grade it. I tried to, but it just fell apart. I tried everything from heavy stuff like FilmConvert to simple RGB curves. Nope. Fell apart. So I left it as it was. Something I pretty much never do! I did crop it to 2.35 to 1 because i love that ratio so much…I also HAD to do something to it! Luckily the image already looks pretty attractive with that contrast and saturation.

It records in H.264 MP4s at roughly 48mbits per second. That’s not very high for four times the resolution of HD. It needs to be a much less compressed recording or ideally a newer, stronger, more efficient and 4K centric codec. H264 is not really it.

I recorded in 30p. There may well be a 25p or 24p option. I didn’t have time to look for it. Doesn’t matter though, as I shot 30p and brought it into the computer via the rather lovely full size USB 3 port at the bottom of the phone, and then converted to ProRes HQ with MPEG Streamclip and then conformed to 23.98p in Cinema Tools, giving me a slightly stronger image and slightly slower but now much nice filmic movement. I really like 30p recording slowed to 24p or 25p. It’s a lovely “not slow motion but not normal motion” look.

Qualcomm Snapdragon 805 processor to bring 4K to smartphones



Designed to deliver Ultra HD quality video, imaging and graphics to mobile devices

CHIP DESIGNER Qualcomm unveiled the Snapdragon 805 processor on Wednesday, which it claims is the first processor designed to deliver 4K quality video, imaging and graphics to mobile devices.
The new chip features the Adreno 420 GPU, which Qualcomm claims is 40 percent more powerful than its previous GPU. What makes the Adreno 420 GPU special is that it supports new hardware tessellation and geometry shaders for 4K rendering, which the firm says produces "more realistic scenes and objects [and] user interface" at lower power.
"The Snapdragon 805 processor is the first mobile processor to offer system-level Ultra HD support, 4K video capture and playback and enhanced dual camera Image Signal Processors (ISPs), for superior performance, multitasking, [COLOR=blue !important][FONT=inherit !important][FONT=inherit !important]power [/FONT][FONT=inherit !important]efficiency[/FONT][/FONT][/COLOR] and mobile user experiences," Qualcomm said.
Said to be the highest performing Snapdragon processor to date, the Qualcomm Snapdragon 805 features a Krait 450 [COLOR=blue !important][FONT=inherit !important]quad[/FONT][/COLOR]-core CPU, which the firm said is the first mobile CPU to run at speeds of up to 2.5GHz. There's also memory bandwidth support up to 25.6GBps, Qualcomm said, for super fast multimedia and web browsing performance.
The Snapdragon 805 is all about streaming more video content at higher quality using less power. It supports Hollywood Quality Video (HQV) for video post-processing, and is also the first to introduce hardware 4K HEVC (H.265) decode for mobile for low power HD video playback.
There's also support for Gpixels [COLOR=blue !important][FONT=inherit !important][FONT=inherit !important]throughput[/FONT][/FONT][/COLOR] to increase camera speed and imaging quality.
"[The] sensor processing with gyro integration enables image stabilisation for sharper, crisper photos," Qualcomm added.
Qualcomm said the Snapdragon 805 processor is "sampling now and expected to be available in commercial devices by the first half of 2014". µ

Amazing that phones will soon shoot "4K" but i still can't buy a decent 4K professional camera that works simply without spending $30K on an F55.
