Antwort von Axel:

A stupid joke, perhaps, but just as I, under the pseudonym (then possible) "Mercury" s.einem first of April this (date and look at the marvel, temperature mutantur) just made stupid joke, the reality of it was outdated ratzfatz I see synonymous here to say it with Dick Jones of OCP, "The future has a silver lining ..."

I find a sweet comment on the YouTube video:

Quote: Will wait until Philip Bloom gives it the thumbs up though.

Wie synonymous immer. Es ist immer irgendwie weitergegangen with der Technik. Wer sich schonmal den neuen Infinia LG FullHD FullLED True3D Television live angesehen hat, weiß, dass einen das Movies nicht mehr lange with demselben Kram ködern kann. Da in etwa Jahresfrist die Digitalisierung in trockenen Tüchern ist, ist 4k dann eine vergleichsweise harmlose "Firmware"-Aufrüstung. Die come quickly, since I bet on it. Even shit, that as a small customer, then sit on his measly 1.8 K (FullHD) remains, the goal must always lie in the afterlife. Or, as WoWu likes to say: "It is exciting." Amen.

Suppose you somehow get 4k data from the sensor, you mean the feeble H.264 encoder has once loose just encode the video in real-time power and 4k Resolutionzu? Well I'm curious.

The 550D has had problems but now produce FullHD, the synonymous really running the full resolution. Maybe you can somehow inflate the video to 4k, but if the picture quality of it's just better to be questionable;)

Antwort von Tuffy:

Suppose she comes to a muddy 4K - which can still obtain a usable 2K, when it scaled down.

Whether that makes sense is another question. I think it is nonsense or a PR gag for lousy YouTube channels, but hey, it's exciting.

How and why then should a high useless 4K by 2K down scaling a useful result?

Space


Antwort von B.DeKid:

So I searched the net, even in times relevant IRC groups there was nothing really written about it.

One should wait and see.

But if all the s Picture to 4K or 8K can inflate even should be familiar.

I doubt it but just that the 550D is synonymous squeezing it, but nothing is impossible to wait then.

Excuse me?

First, new and different binning algorithms on it.
Then the de-mosaicing with other weights are provided and if the of is the "hackers" all successfully carried out and implemented, then I just happened times the data rates s.and notes that the processor has not have got done so already meager data rate and it would be enough for now just 3.3 frames / sec.

So go forth and implement other hackers Profiles of H.264, and other tools synonymous other methods, only to discover that you could manage that, then with so modified firmware and the related higher data rate.
And they would then arrived at the store .....
..... Should I do next?

My God, how naive must one actually believe such a thing.
Of course there is one day 4 k itself from such cameras and then you know synonymous, on which monitor you should go to and which wall you have sacrificed in the living room for it or, if not, whether you prefer 30 cm, or at least better 40cm away from the monitor sits to 4k see at all.

Man Man, the first time to 1920x1080 with 50 images from both the Lens, as synonymous manage the processing properly. Then you can calmly think about the meaning and purpose in of 4k.
But I can see again from beyond:

The more pixels, the better ...... Bullshit.
In the sense ... Happy.

I think it is not entirely unlikely that the large-Camera Manufacturer cameras "artificially" limiting the market to leave race piece by piece.

After all, one must indeed innovation and storing it can not burn unnecessarily. Ordinary strategic marketing campaign.

If Canon wöllte really, it would be for a child to play a perfect 4K video camera for a few thousand euros on the market to bring.

The problem today is that all the know-how is in big corporations and the resulting quasi have the power to withhold technical development until it is required by the competition will follow suit.

I do not synonymous, it would now give Alexa in its current form, if it were not RED.

But that is synonymous s.Thema already past.

I believe that through firmware modification is more in it, as allowed by default by the Manufacturer. That 4K and 175MB / s work I do not synonymous, but I would be happy if I get a better informed s.Samstag! Then I would not synonymous question is whether the technology or not ;-)

Antwort von WoWu:

Well, no it's not because the processing times of a single pixel now takes 30 ns.
These are still just the parameters of the sensor by itself determine its type (and this includes the heat) and from the time you get beat then synonymous moving pictures. With all the side effects, a higher clock does so with themselves.
And if current through conductors "flowing", produced takes a look at heat. This will change the way no longer synonymous.

Yes, I agree with you that many a camera is artificially limited, and it was only to save Inch or taxes.
And I believe synonymous, it is possible that at some point to bring a camera for 4k <1000 EUR on the market.

Only that this should be managed and it has all the cameras in "dormant", alert only of a business-minded "hacker" to be .... With the best will, because You do not turn themselves.

This is the way with the car and the air.
Theoretically, every car ride infinitely fast and consume minimal fuel.
It just lacks only the hacker who makes sure that it travels in a vacuum.
So $ 50 for the experience .... You have already paid?

synonymous if the expert you understandably just running amok, the monetary printing press is only the 3rd release start, the first two will be free of charge, enough space, to test the allegations before anyone paid. That as yet there is no evidence, is surely normal. So rich is the lest.

If this is all just a fake, makes himself as much of a damn easy: say for example now, probably never 25fps ... Incidentally, the audio is now to be found under the above link.

Antwort von Axel:

Well, 175 Mbit calculation are four times what the 550 now, with just under 2k, consumes, which I had synonymous Sun invented, if I could do to make credible. As a "Game Changer" (Rudi), one could only call it when everyone would lust after 4k. But at present there is probably no need: Nowhere is the standard, that is where to put it? I see it more as a warning. Will we someday have enough resolution? Quoth the raven: Nevermore!

Maybe they should first be reached in 1920 clean ...

I've learned so. If you have such material in FullHD 4:2:2 (HVX 200 for example) and then be scaling down (to PAL, or even less), the subsampling increases.
The events I describe to you, of course not - they said, at least in Hollywood Camera Works "Visual FX for Directors".

The HVX200 magic of a chip with 900 000 pixels of a video with 2 million pixels (pixel shift, whatever that is, at least one trick). But suppose one would 4k down traffic lights on 2k, might not be 4:2:0 Rausklauben from the "real" pixels are 4:2:2, as most suitable for keying? If we imagine the pixels as a mini-plug squares - and we must - it is not enough to keep only one in four small stones in order to reconstruct the picture, the entire picture must be inserted again. Depending on the quality of the formula, with which the calculated, the quality can be very good. And of course, the video synonymous "as" are calculated 4:2:2, with some benefits, but not with those one expects of an original 4:2:2 Recording (keyword Keying).

Antwort von WoWu:

In a sub-sampling is always made of two color values, a common color value that is then transmitted.
This starts s.Sensor!
Bayer mask has, for example, only every second "line" the necessary values and horizontally and thus effectively synonymous 4x subsampled vertically.
The result is thus already a mixed color. Now on 4 levels.
These mixed color is transmitted as a color value. All samples in the data stream are filled, only there, sitting where the original individual colors should now sit two mixed colors.
So it is no longer possible, from the mixed color ever to restore the individual colors.
If one now before image reduction, this is done by interpolation. it is restored from different points of another color mixed color. The color value is removed always next of the original individual color of each pixel.

Many present themselves as simply missing color samples in the data stream that can fill up again and so again from 4:2:0 4:2:2 makes by simply leaving out lines ... or something like that.
may be this is a naive idea, because it is the original color after a sub-sampling is no longer synonymous and so the emergence of the blend color do not reproduce.
Also missing in the data stream never samples, because monitors need all samples for a presentation. Only the repetition of samples show flat or only a pointer to the sample.

So no preference, which is made back, if not 4:4:4 or 4:2:2 coming from the sensor, you can enlarge or reduce, as much as you want. A pre-mixed color is a mixed color.
Sub-sampling is not a question of mathematics or the amount of samples but a statement about the quality of color reproduction.
Therefore, it is synonymous no preference, which form the original image area and had since worked with was whether or not Shift Shift.
A word to the 3:1:1 sample format as it exists for example in HDCAM.
Commonly said is said, the "3" with the recording format 1440 x 1080 hang together, because in 1440 some 75% of 1920 and is therefore synonymous only 75% of "4", ie approx. is scanned "3".
This is of course wrong!
It is true that in the HDCAM process one block of 3 color samples (instead of 2 at 4:2:2 or 4:2:0 at 4) are drawn together and has nothing to do with the Prefiltering the recording format.
It is simply the ratio of color scanning for Lumaabtastung.
