Accessories: Nokia 808 PureView Picture Frame, + Could 4K video recording be possible by 808?
Well, not really but Gerii who tipped this in pointed out that this would make a good companion for your Nokia 808 PureView as it could show the pictures from the 808 at 1:1.

This features an 8K screen, 7680 x 4320 or 33MP.
Now whilst 145″ might be impractical for everyday use, 8K is certainly where we’ll be heading in screen resolution. This reminds me of a post I intended to make some time ago where James Burland talked about the possibility of the Nokia 808 recording 4K video.
There’s no one quite like James Burland when it comes to speculations about technology. Whether it be about Apple or more appropriately for us, Nokia, if you’ve been following him for a while, he’s freakishly always on the money.
James, Mr B has long been passionate about mobile imaging, and for a very, very long time, Nokia has been at the forefront in driving innovation in imaging forward. Here were some links I dug up from his archive, some very, very smart speculations (well I thought I had more links but seem to have lost that draft).

On 4K video, James says it’s about Future Proofing. We’re always hearing now how some phones ‘aren’t doing 1080p’ as if it’s now a standard, but so many years ago, that would be considered crazy on a phone. If you jumped back in time to 2006, I’m sure you’d also get asked why on earth you’d consider recording 1080p or why even you’d have HD screens on a 4.5″ device. James reckons 4K displays will be the norm soon enough.
Imagine if screens would eventually have the same pixel density as the latest HD phones. That would be some insane screen (requiring some insane powering) but it wouldn’t be impossible.

My theory :
1.) Video Cameras like sony Nex fs700 do 4k video recording by interpolation and not true 4k capture. Results are good.
2.) conventional cameras produce images and videos using bayer interpolation…
3.) according to whitepaper, 808 eliminates bayer interpolation packing thrice the number of true pixels than a conventional camera
so a 1080p video from 808 theoritically should have the same amount of detail as a 4k video using same hardware.
“1.) Video Cameras like sony Nex fs700 do 4k video recording by interpolation and not true 4k capture. Results are good.”
Well, actually, almost ALL (photo) cameras out there use line skipping if their sensor is bigger than Full HD / 2k / 4k / you-name-it. I sincerely hope the 808 does ful binning. (I’m not sure about it as it does require a LOT of computational power. Dunno if their dedicated camera CPU is capable of downsampling 38 Mpixels 30 times a second – we’re speaking of freaking high data bandwidth…)
Nokia says the 808 hardware overall can handle over 1 billion pixels per second during HD video recording. So theoretically, 4K video should be possible on the 808. Whether it will be is the big question.
It downsamples 34MP at 30fps, since it’ll be in widescreen mode. And as n8thegreat says, it really has the hardware to do that, in the form of a co-processor attached to the sensor.
I assume video compression is handled by the GPU though, which may not be able to go above 1080p. Speaking of which, if the GPU really is the same as the one in the Belle batch of phones, shouldn’t they be able to do 1080p video also? EDoF video is pretty cool.
Do you think it could be possible to take a video recorded on an 808, and use an algorithm to reverse the downsampling process?
I’d love to see that, although I suspect the compression will be too aggressive to give good results.
Come to think of it, have we seen an example of 808 video that hasn’t suffered from additional YouTube compression yet?
“Do you think it could be possible to take a video recorded on an 808, and use an algorithm to reverse the downsampling process?”
Sounds impossible. After all, you can’t create a higher-resolution (say, 2k) video out of a video only stored at, say, Full HD resolution using 1.06 (2048/1920) anamorphic stretching. (See for example my dedicated resolution tests between true 2k and Full HD * anamorphic 1.06 stretching at http://www.iphonelife.com/blog/87/new-ipad-3-2k-video-playback-definitely if interested.)
I mean, if the video from the 808 was separated into a red version, a green version, and a blue version, and those 3 videos were repositioned onto each other to match where the red, green and blue sensor pixels would be in relation to the final downsampled pixels, it could be a little higher resolution, couldn’t it? It wouldn’t really be cheating any more than regular digital cameras do all the time anyway.
It would probably only have a chance of working if the 808 only uses one instance of the Bayer pattern, or one RGB set, for each pixel though, but it uses far more than that (16 pixels or so for 1080p?). And if that can be programmed in, may as well reprogram the whole unit to save videos differently anyway.
I thought the 808 uses the extra pixels for zooming in 1080p video mode, not for binning?
Binning. To my knowledge, they do bin in video mode too to deliver better noise performance and avoid line skipping moire artefacts so visible in almost all DLSR videos, except for the Pana GH2.
After all, they deliver 26mm wide angle during video – this would have been impossible without using some kind of binning.
shit
where are u gonna store ??
symbian cant allow storage of more than 4gb(fat32)
may be if its hardware capable but
right now its impossible !!!!
Ever heard of file spanning used in many cameras like those of Panasonic?
An excerpt from my mail sent to the Nokia 808 folks on exactly this matter:
“2 Video mode
2.1 Allowing for recordings over 4GB (and, of course, 30 minutes, whichever comes first)
That is, allow for file spanning over 4GB to allow for recordings of any length. When a 4GB file has entirely been created, the recording should continue to a newly, on-the-fly created file.
Currently, there are two approaches to the continuous file naming:
a. Panasonic’s (a manufacturer offering unlimited recording times in all their digital cameras (most importantly, the GH and the TZ/ZS series) not meant for the European market) approach doesn’t use a special filename convention to denote spanned files: the newly-spanned files will just have an increased serial number (for example, 00010.MTS following 00009.MTS). However, (for video editing programs as well) it’s very easy to spot these spanned files: the size of the already-closed ones is always 4.29 GB (4,292,499,456 bytes) and the filedates are also the same.
b. several sports camera makers (e.g., that of Race Optics T.A.C.K.) use the filename convention of the same final serial number (as opposed to Panasonic) with an in-name counter to show the in-series serial number of the current file. For example, let’s assume the camera starts recording to a file MVIV0012.MOV. When the 4GB limit (with some of these cameras, exactly 3,937,891,052 bytes) is reached, a new file (MV010012.MOV) is spanned. The counter in the third and fourth character index is 01 for the second file in the series (that is, the first to be on-the-fly spanned one). The filedates of the files in the spanned series, as opposed to Panasonic, reflect the creation time of the individual files and have, therefore, not the same timestamp.”
well bro
if ntfs support is added
we can get in 1 single file
it would be mess in both methods u suggested.
30mins of 1080p=4gb
for higher resolution u need higher bit-rates
so for 2k or 4k,4gb limit would hit within
5-15mins
may the wp pureview might solve this prob
since ntfs is of MS
she really doesnt have 808 stuck against her palm….eh? Jay
Ha, no but it was begging for it
Good eye 
Argh! Now I’ve noticed that her right hand is massive! For her sake I hope this is because of perspective warping from the camera that took the photo.
It would be nice to see some sharp videos. But we’ll need SSD’s for cell phones and SED or FED TV’s will be needed to watch it in full colours…..
When would we see pixel/atom?
If you meant write speed caps of current storage cards making it impossible to record decent 4k footage, you can still use HDMI (or other, very fast interfaces) and an external e.g. SSD recorder, as is done by several pro video companies.
8K television? Unless it’s completely filling the viewers field of view (it would have to be shaped like a concave hemisphere), 4K pushes the limit of human eyesight on a very large TV or cinema screen.
If I went back in time to 2006, I don’t think 1080p video recording would be too big a shock, given that the displays and digital cameras already existed and could be bought in high street electronics stores. But if someone asked me why we have HD display displays on 4:3 inch screens, my answer would be ‘marketing’ or ‘external battery pack sales must be quite lucrative’ or ‘blame Apple”…
In 2006, VGA (480p) video was a big achievement for a mobile phone.
Yeah, “DVD-Like” recording quality, as Nokia marketed it, was WWWWAAAAAYYYYYYY ahead of any other phone on the market. I loved my N82′s video capability, coupled with the excellent (for it’s time) audio recording.
I have videos shot via my N82 of me and my kids riding Go-Karts when they were younger. I am so glad I had the N82 with 640×480 video as I can see everything and the sound quality is fantastic. I don’t have to guess whom it is that I see on the video.
If I would have had some of the other phones at the time….the playable memories would be unbearable to watch and a loss.
