Infoseite // HDV has only half the HDTV Resolution



Frage von inwa:


Normally, HDTV has 1080 one Resolutionvon approximately 2.07 Megapixel (1920 x 1080 pixels). For the commonly specified Resolutionvon HDV 1440 x 1080 pixels would need a camera) of 1.55 megapixels (per chip. In the 1080s, the horizontal mode Resolutionvon HDV compared to the normal HDTV format is thus reduced by 25%.

Sony's flagship HDV camera HVR-Z1E has only 1.07 megapixels, which corresponds to a Resolutionvon 990 x 1080 pixels. HDTV 1080 compared to the Resolutionalso is reduced by almost 50% synonymous, and in the small HD 720 mode is reduced Resolutionum about 23%, since only satisfied with 990 x 720 pixels can be used with 1280 x 720 pixels.

In the "pixel shift" in principle, be made 3 recordings and interpolated. It is synonymous with only 1 chip cameras and video cameras with hardly the need to have 50 frames per second:

"JVC has also dug deep into the bag of tricks to increase the already considerable Resolutionvon 3.34 megapixels in its GC-X1 Digital Camera again. Two shifted by one pixel images that are made in a split second, can the two pictures with different filter colors are included - the information in the green area can be collected 100 percent in the red and blue color need to be interpolated, only 50 percent. The "pixel-shift" technology is referred to only one of three settings based on double exposures, the JVC to improve the image quality s.seiner new digital camera offers. "

PAL can be compressed in the way of Austrahlung synonymous almost 50% to 440 lines.

Antwort von inwa:

Correction: It says: "Pixel Shift" is one of three double exposures based setting option. If this is true need to be made 6 frames and interpolated to generate a picture. 25 times 6 makes 150 frames, which would process a Vidoekamera second. That seems to me something much more abundant, not to mention the fact that the Belichtungsezeit should synonymous corresponding to shrink.

Why DVCPROHD with 4x provides higher data rate is even less Resolutionals HDV (1440 x 1080). To say nothing of the full resolution (1920 x 1080). The should be in MPEG 2 format, even with 50Mps (DVC PRO easily equal 50) for?

Tape on an even higher data rate ends up, for the 440 Mbit / sec, so apply only to the video, audio, there is added again. Total (including audio) is about 600 Mbit / sec.

Antwort von Niklas:

HDV uses an Interframe Compression:
Images are placed in groups (GOP: Group of Pictures).
The first frame (I-frame) enrhält the full image information, so the full resolution.
In subsequent frames (B and P frames) are only the changes to the I-frame was added. They have, therefore, only a greatly reduced resolution.
No problem, until a movement comes into play. Then, of course, as many pixels as amended, that the fixed data rate of 25 Mbps is not enough.
The camcorder is reacting to that, he Resolutionreduziert, and it produces Artekakte that are masked by blurring.
HDV has also (ideally just standing with no motion picture) the full resolution.
DVDPROHD contrast compresses each frame individually (intraframe) compression.
With the same codec as synonymous already DV: One further development of the Motion-JPEG codecs.
Thus, each picture full resolution.

Incidentally, it is a difference between what the chips and start what will ultimately end up after the compression on the tape. Everybody does it differently Manufacturer.

Antwort von deepcode:

So to say it this way too - IMO HDV is clearly a good thing, and HDV cameras save a higher Resolutionbzw. more image information s.als DV cameras. It should not be fought only with false expectations - HDV is not HD, nor is such as mini DV not Digi-Beta!
HDV is a consumer format with which you get - if you know how - very good, and better results can be compared with DV.
The major disappointment of many is certainly the fact that video - just because it dissolves more - not car looks BETTER, but still the look of a film is critical - light, depth of field conditions, camera work. Whoever wants to make movies is the same with an SD - Camera and if he has a clue of what he does, the film is to be funny - something more or less sharp plays absolutely no role.
And if I can not shoot with HDV 1000 sheets then I lay it flat. When I am with a 100,000 EUR 35mm ARRI make the famous horizontal rotation in the pine forest I get from the progressive tremor synonymous headache - so I let it be also better.

HC1, however, is a small example, a good thing, because properly handled so that you can get with your results under most conditions, such as with an XL2, and with minimum size and weight. And that's schonmal lot!

Antwort von wolfgang:

720x576 50i, you should already be compared with 1440x1080 50i, and halving the HDV format nix da. In both cases, is recorded in interlaced fields, the fields are always 576 / 2 and 1080 / 2 lines.

But this is not the point. The point is that the material to the present HDV2 vision devices ala Plasma, LCD or projector must always be deinterlaced, which naturally reduzert the Resolutiondes material. So is 1080 50i is not really better than 720 25p.

Strictly speaking, a Halbbildaufzeichnung today would be an anachronism - in fact no longer necessary, if one had not unbedint the 1080 50i material ban on consumer mini-DV tapes ala want. I think it remains unchanged forecasting shame that we are apart of the JVC HD101 is still no real 720p camcorder in the upscale Prosumerbereich have. But perhaps that is still yes.

In any case, it would be good if the development would go to 1080 50p, or of me out to 720 50p. Whether we are working with DVC Pro HD, and to record on disks or chips, will be the next question.

However, it's just as synonymous: who wants to film high resolution earlier today in the consumer area already, which crops up s.den HDV camcorders do not really over. Or he will stop at mini-DV. But I can say only one thing: who has the distinction of these devices on a plasma to DV avi seen, even, who like me only takes the PD1 as a cross between HDV and DV-avi, which becomes clear how big the difference in quality simply is. Sure gibts limitations - the leaves example - and clearly you have to just deinterlace the 1080i high-quality material. But for the price of 1,500 euros to get the consumer area, but a very good device.

Comparison with the HC1 to an XL2 synonymous probably makes no real sense - these are very different devices. Rather, one can compare an HC1 with a 400 of Panasonic. If you want to compare the XL2, it was probably either with the XLH1 (as synonymous here) happens, or with the upcoming Pansonic HVX200. Or synonymous with the JVC HD101.

You need synonymous in interlaced mode 1440 x 1080 pixels. However, according to articles in photography (which is not always synonymous to read the right thing) is in interlaced mode two lines coupled Weden read. To conclude from this that the Resolutionnur would be 1440 x 540 but is wrong. The synonymous you can easily keep track of when you imagine that you are capturing from the tripod a Picture.

The Canon XL H1 has 1.56 million pixels, therefore the full 1440 x 1080 progressive fashion Resolutionund is synonymous in the 1080s of great resolution, but where is the interpolated picture of two fields. To that extent it is questionable whether there increases Resolutionsich.

As written above, you can expect at 720p probably still around 20% on it. So instead of 0.9 we arrive at about 1.1 mega pixels. True 1080i but has 2.07 Mega pixels - then it was twice the resolution.

This again is only half the truth - in fact it is worse. Sense of a video camera to record moving images. And here's the problem:

Moves in the picture has nothing to Camera full HDV resolution, synonymous in interlace mode. Logically, because changing the pixel of frame to frame in None manner.

Once the motion picture is halved, the area resolution (pixel count) in favor of temporal resolution () 50 instead of 25 frames per second. The lack Resolutionwird more or less well-calculated from the movement. Therefore, panning and motion blur will act as a still image, even at the shortest exposure times.

I would prefer a decent 720/50p a 1080/50i (1440x). Would be acceptable even synonymous 1080/25p.

So just the Progressivemodus the XL1H is far from being as good as a good software deinterlacer. Apart from that seen in the semi-professional HDV and most skilled craftsmen very critical.

Thus, the Profie is currently assessed by the computerized remain rather, because the risk of dropouts is still very high for HDV.

But just make cool movies and take what is available and affordable!
Since HDV is quite ok, who wants something better may indeed spend per day 700 EUR for a F900.

The XL2 looks pretty cool, is difficult and has interchangeable optics.
That was then synonymous already.
It is crucial under what conditions do what I can achieve results.
Zb under controlled lighting conditions, I am a little sharper with the HC1 and from her look hinbekommen similar images.
Under difficult conditions, the XL2 with its many parameters is (front pedestal, black levels, etc.) comes with no HC1 or FX1.
When guerrillas - Shooting with the HC1, I have the absolute space advantage, because it does not itch - introduce yourself with the XL2 to go somewhere that is after 1 minute and want to see someone there filming permit.
Sales, however, will be a fiasco if you with a winz - cam as the HC1 markups, no preference is how well.

Interlaced:'s just been the usual news and sport look, since i provides high motion resolution.
Deinterlace costs prnzipiell only Resolutionbei moving image parts. However, synonymous with progressive images cineshutter (1 / 50 or 1 / 48) are completely blurred.

Let's leave the church in the village any more than it is right to say that HDV would only SD resolution possession, any more than it would be fair to say that would have required deinterlacing of 1080 50i to progressive vision devices performing any loss of quality. The fact there is.

The viewable quality difference between 720p and 1080i are definitely relatively low. This is plenty of empirical studies. And that we can fully exploit a 50-inch plasma HDTV Resolutionauf not really, no news is synonymous. We consider only the pixel size of HDTV and HDV2 - and then think about whether the human eye at normal viewing distances in our living rooms still can not resolve the difference. It may be virtually impossible more.

So, as I have the thing in his head, was up to 50 inch, 720 50p (not 25p) Material of test groups considered to be better, compared with 1080 50i. And that is exactly the point: more than 50 inches are expected in most living rooms, the plasma or LCD displays do not go, it would even be allowed devices often remain only 42 inches.

So what is the Jammerei that you necessarily would Resolutionbenötigen full HDTV?

For still images, there is theoretically no difference in my opinion. For a given viewing distance, the picture would naturally appear gray in both cases, incidentally, exactly as if they had ever taken a gray area. In this case, the progressive frame, but synonymous, the two partial images in Interlaceverfahren would be gray.

It is about the so-called Kellfaktor. Out of 100 lines can be interlaced with only 65 black and white lines are shown. In the full procedure is supposed to be 85 to 90. To that extent a theoretical advantage of resolution is expected 20%. Through good Nachberarbeitung, however, can achieve clarity benefits of up to 400%.

Even in the horizontal direction is the way with 100 pixels, and represented only 77 lines of black and white lines. The difference of 25p to 50p will be minimal. To that extent would eigendlich 1080p 25, the best format.

What is übrigends a major advantage of HDV to DV, synonymous if the end result "is only" on an SD-DVD, is the higher color resolution. DVD-compatible MPEG2 provides sharper colors because, as DV. That is, if you burn DV footage to a DVD, the potential benefits to DVD quality is not enough. And is stronger when keying or editing the whole much more problematic.
