Infoseite // Take pictures in 16:9 camcorder with 4:3 CCD chip even make sense?



Frage von newuser:


Hello!

As I read, almost all camcorders (and I own a Panasonic SDR-H80) a 4:3 CCD chip with which the recording is created. If now as a 16:9 format that will be used only 720x400 pixels of the chip and then the Picture "electronical" vertically stretched to 720x576.

1. Question: How do we pay? This is but the geometry of the image vertically moved? (; analog recording anamorphic horizontal)

When the picture was then "stretched electronical" is still in the picture is not more information than was originally in the original image of the chip in 720x400 format.

2. Question: As a result the image quality is poor but oden are playing with a 720x576 to play with the original 720x400 (; under insertion of a corresponding black bar and below)?

3. Question: Is not it more useful to include in 4:3 and then render the movie with 720x 400 to? I save space and the image quality is better, but live with output to a TV with black bars above and below (: what can be very charming indeed synonymous).

For useful information I would be very grateful! ;-)


Love Greetings

Your newuser

stands so in the Instructions? Would be surprised mcih.
The cam has a 0.8 MP sensor, if I'm not mistaken. Even if that is in 4:3, stay left for pixel 16:9 for about 600,000. However 720x576 is only 414,000.
Either way, the picture will be runterskaliert.

Hardly think that that makes sense.
If you have a 4:3-TV, perhaps it makes sense to include in 4:3. But if s.end 16:9 should be, you should like so synonymous record.

It is true however, that a 4:3-chip camcorders with slightly better quality than 4:3 in 16:9.

Again, what to learn ;-)

Thought of the CCD chip is always in 720x576, that is 414,720 pixels.
Is in my manual:

1 / 8''CCD image sensor
total of 800 K
Effective Pixels
Movie: 400 K (, 4:3), 370 K (; 16:9)
(; The output format of my camera is 704x576)

- None So 14,720 pixels at a 4:3 recording?

What about 16:9:
- The output format is still 1024x576?
- Also missing 219,824 pixels in a 16:9 Recording?

I understand that right?

The output format to a PAL SD camera was supposed to always be 720x576.
Even at 16:9!
The pixels are not square halt.

As used in less 16:9 and pixel sensor surface, the detailed resolution and sharpness probably be somewhat lower.

With a 4:3-TV, the picture yes, then with 16:9 or less (; bar is) making it onto the same visual impression comes out as 4:3.

On a 16:9 tv, the will but we do make all the more noticeable, this is your camcorder is no specialist 16:9.

Antwort von newuser:

And what cameras are then 16:9 specialist?

What can I get a better picture if I want to watch my movies on a 16:9 television?

In a recording in 16:9, I
- (On a 4:3 television, a clearer picture;) than on a 16:9 TV, but the top and bottom black bars.
-At a 16:9 television to a worse picture but no black bars

And at a recording in 4:3
-is on a 4:3 TV alles prima
-and a 16:9's it looks really blurry

no, on a 16:9 sees it as from sharp, but you have the right and left of the black bars.
Or do you merely zoom, and the bars are gone, but then the picture below and above circumcised (; and is determined by the zoom is of course synonymous worse).

Antwort von newuser:

ok! thank you for the info.

So I was with my super Sony Plasma TV 16:9 .. ;-) .. better record in 16:9 - and adjust myself to the fact that the picture is not so good as of a commercially available will be dvd ;-)
The thing that is automatically zooms to 16:9, and makes off the side bar, at the expense of the picture ...

But it can leave no doubt or at least manual change again.

If you want to watch your videos in full screen in any case, you should immediately start to 16:9.

@ Newuser

Most camcorders have built-in 4:3 chips ... often only with a higher resolution.
For a chip with 800,000 pixels for 16:9 you have never recorded more than 1033 pixels horizontally and 581 pixels vertically available.
That should be enough for SD.
However, you lose the color mask for a re-usable resolution Einchipkamera and Land, depending on which algorithms are used, such as 620x465, that is only slightly below a full resolution SD. The rest is now cosmetic.
Only when you have 4:3 synonymous base resolution no higher because s.den usable horizontal 1033 pixels does not change ... only in the vertical you could use 775 pixels, but this makes for a 576er Picture no.
And so that your resolution quality with 4:3 and 16:9 is absolutely identical.
Ergo: 16:9 even makes sense to 4:3 chips .... But more would bring a 3-chip camera, because the de-mosaicing would not affect the image resolution so.
