Frage von atrichter:
Hi,
I have for a few days a
VX2000 and try everything for the first time out and read a lot, synonymous here in the forum. When you set the function of 16:9, the camera cuts away the top and bottom of what used ie not the entire chip, if I read correctly the. Now there is an attachment lens, which contracts the picture so that you can see it in the widescreen format, and uses the camera the entire chip.
Now it has, but still a menu functions in the Picture is synonymous contracted. menu item called SLIM and provides a picture that depicts a ball as an egg. Can we not use synonymous for 16:9? It is synonymous but used the whole chip.
Thanks in advance and sorry if this was a stupid question.

When the chip is 4:3 and the camera produce a 16:9 aspect ratio is, she can use according to Adam Riese never the whole chip, no preference whether the picture is then displayed as letterboxed (black bars) or anamorphic (eggheads).
Antwort von Ephraim:
Hello,
With Adam Ries has little to do. Synonymous, he says something else:
I think the company is called Century, or something like that. The intent to build a lens, which compresses the Picture s.den pages, similar to how one can accommodate a synonymous 35mmFilm a wide screen image. The compression s.den pages is because we know that lie bildwichtigen information in the middle, in an area covered by the 4/3-Format and s.den equalization pages less noticeable, even when the image is not exactly is. It is used while the entire chip, but it is still a compromise.
With the digital setting slim the entire picture is drawn together. How this affects the equalization in the 16:9 format, I can not say (no time to try it). But I suspect it will be using a different distribution of pixels or other pixel format. If you want to test it, you should use the Siemens star, or a similar scan images, photographs, and make comparison of the results reported here.

My statement was referring only to the 16:9-camera functions, rather than the optical resolution.
When you set the function of 16:9, the camera cuts away the top and bottom of what used ie not the entire chip, if I read correctly the. It is even more complicated. The camera reads only the center section of the chip (ie, the 16:9 Extract from), but then stretches out the picture to full screen height (576 pixels) and thus plays in the technical sense "true" to 16:9 on tape. For analog playback on the iPod's display and / or a 4:3-connected monitor can zurückstauchen the camcorder, however, the picture back to letterbox, so it looks when you play it as if it would have black bars.
Whether you want to have real s.analogen output 16:9 or letterbox, you can set in the menu somewhere, which then refers only to the playback. No black bars on tape will be recorded.

That was the core of the issue.
The camera uses the entire chip, produced but a shrink to electronical Picture, in the editing program, which is set to 16:9, is equalized to the full width. The question is really whether this equalization is a real picture, so the ball is referred to the egg again, and how it is with the Resolutionverhält.
Antwort von Jan:
Yes, the VX 2000 is one of the models that only about 75% of Resolutionbei 16 / 9 use, as written do not take advantage of the CCD.
Without the raised Anamorhot (same as VX 2000 Century has widescreen 16 / 9 adapter, 58 mm), it would be of advantage even as late as 4 / 3 and later s.Schnittplatz to shoot on 16 / 9 rauszuholen to change, at best. The reason would be the Quantisierungsquadrate have a fixed data rate and can not be redistributed.
The VX 2000, namely, 16 / 9 no longer 720x576 or 720x432 only.
Expensive 16 / 9 cameras have real 16 / 9 CCD's, in the signal processing electronics that actually reduces the recorded 920x576 back to Pal's level. In both cases, the picture is compressed horizontally recorded and equalized only when playing, either with the bars (letterbox) or in full screen size (16 / 9 Television).
All professional nonlinear editing systems can implement this equalization in real time during playback requires the cutter but a 16 / 9 compatible display or editing must be done to cut film on 4 / 3 to convert with letterbox.
The Century 16 / 9 adapter compresses the Picture at the Studio in the 4 / 3 horizontal mode - the electronics can use so that the whole chip size. The Wide Anglevergrössert is thus synonymous to about 33%. Visors can unfortunately not be used with the adapter. The exact dates I found in an old VAD.

I've tried it (even with a TRV900) and that provides the image detail in both cases (16:9; Slim Effect) from nearly identical. Except that 16:9 is recognized by the Television synonymous as such, while the Slim-effect provides only a distorted 4:3-Picture. When capturing this could be corrected, although again, but nothing more is why Resolutionbekommt.
As a camcorder lens should be synonymous to switch between "normal" and anamorphic, to use an existing 4:3-image converter, on the whole surface? - Exactly, that indeed is not at all. Although glass is a liquid, but so quickly it flows synonymous again not that of the lens by pressing a button on the anamorphic lens. ;-)

The pigs expensive Anamorher of Century / Optex to get this done and take advantage of the CCD was completely VX 2000 / PD 150 does not provide the 16 / 9 mode
.
I've seen pictures with and without the adapter with SonyPD 150 - have you with Century 16 / 9 adapter really much more on it right and left, the picture looks so rich detail - no joke.
Without adapter with the PD 150 was seen only one tree to the left, with the Century adapter to its left nor the second - the right is synonymous more detail, the test forest landscape is incredible, can not show, unfortunately.

The question is what am I in identifying, is whether the Slim-mode achieved what reaches the anamorphic lens. Of course, you will not see trees as the "compression" do not find optical, rather than say before the image plane, but on her. However, I can picture in any mode of cutting Widesceen wide program and get on the control monitor an appropriate 16:9 Picture. As it looks, however, if the equalization, as is done by the expensive optics, not only s.den sides, but on the whole picture? If the "egg-shaped swaged ball back to the round?
I can do that here, where I just do not try ....
Antwort von Fargonaut:
An "equalization" in both directions is no longer remain the proportions of synonymous and allso get the egg is an egg. It is no use of a camera designed for 4:3 you can just only with a real expensive Anamorphic 16:9 anamorphic picture using the entire image sensor to create, which is then recorded in 4:3 stretched to 16:9 and subsequently re - be.
Antwort von Fargonaut:
An "equalization" in both directions is no longer The Slim-mode compresses only the horizontal, but not the vertical. If he did this, would arise from a ball no egg is only logical, right?
But no one seems able to answer relevant questions about the host. So I have him put off until I'm back where the technology is. Then I make a few shots with the Siemens star and put it online.
Antwort von Markus:
But no one seems able to answer relevant questions about the host. Good, let's try:
When you set the function of 16:9, the camera cuts away the top and bottom of what used ie not the entire chip, ... That is correct. It is read only the part of the image intensifier, which is necessary for the Height of the 16:9 image. The width is unchanged, from 16:12 (= 4:3) is 16:9.
Now there is an attachment lens, which contracts the picture so that you can see it in the widescreen format, and uses the camera the entire chip. This is a so-called anamorphic lens, as mentioned already described next.
Now it has, but still a menu functions in the Picture is synonymous contracted. menu item called SLIM and provides a picture that depicts a ball as an egg. Can we not use synonymous for 16:9? It is synonymous but used the whole chip. I just tested it: The Slim-effect distorts the picture more than the 16:9 compression does. That is used in the Slim-effect the entire area image intensifier for image generation, is a mistake.
So if you want to use an expensive anamorphic lens, 16:9 would be the setting of your camcorder, the possibility of choice. That you may see the Picture synonymous in the viewfinder or on the screen without distortion.
