Newbie fragt: warum wird 720x576-Format auf 16:9 Fernseher beschnitten?

Newbie asks: why is 720x576 format to 16:9 Television pruned?



Frage von holgerbgl:
Juni 2008

Hello!

I have MPG material of my SonyHDR-CX6. 720x576
Can I import into Studio 11, make a movie of it, burn to DVD, and then missing on my 16:9-television left and right a piece of the picture.

Why is this so?

And what can I do to make me the best possible quality on my television can not picture pieces to lose?

When I look at the camera directly connected s.den Television missing so synonymous nix ...

Sorry if the question is "stupid," I'm just totally new (and I did everything just simply synonymous presented) :-(

Thank you!

Holger

Gudenåen

How the Project was created, perhaps 4:3?

Because s.der Page missing for a 16:9 TV sounds depending 4:3 to 16:9 is not running on.

Did you time the video s.einem 4:3 test device?

MfG
B. DeKid



Antwort von holgerbgl:

4:3-on device is missing even more, left and right.

I watch the video on my 16:9 laptop, I have above and below a black stripe.








Antwort von B.DeKid:

Do you have times the material on the DVD checked, is to say are 756 x 576 or 720x576?

Because on the Strip Lap top / bottom is rather normal, but the picture is cropped side is rather unusual.



Antwort von holgerbgl:

well, it is not trimmed the side.

Left and right stands the Picture "on the Television out" - because obviously I can not see it.

it looks like a much too broad picture that does not fit on the television.

The Project has the following format:

720x576, interlaced, 16:9

why does that not apply to the Television? Grummel.

How can I understand the Resolutionauf DVD rauskriegen?



Antwort von B.DeKid:

So I hold times together.

DVD Picture is now bigger than the TV screen.

Technical data of the camera at the Sonyauf Page

I can not explain it `s what a Resolutionhat which the video footage if / before you put it in the studio?

Was it perhaps in the AVCHD format and was gecropped to 720x576?
Was it perhaps shares Picture disappeared? Can the studio so already circumvent `?

But what you said of MPEG ..... because of what is VGA 640x 480 in the Technical Data Could be .... but no picture synonymous proportion missing?

Sorry, unfortunately I can not help you because .... because who needs qualiviziertes answers.

MfG
B. DeKid



Antwort von holgerbgl:

So I suppose in SD quality, not AVCHD.
MPG2 format. Size 720x576.

I prefer the simple studio. The preview is synonymous all there. I watch the DVD on my laptop, everything is as synonymous. Only on the 16:9-Picture Television is so big that the left and right parts are no longer visible.

I once ask me who is the culprit here?

Studio? The Television? Or do I? : - /

(if I have the text layer to add text, appears as a red frame that somehow the size seems to be how the then visible on the Television Picture - whether's is a hint?)

Times like this I go out, you have the standard of Pal, Pal is not widescreen (which cut Schummel Broad, above and below what is omitted), or? (That would otherwise be expanded even more)

My proposed solution:
Create a standard PAL Project and let your Television scale, or turn on your television so as you do in television synonymous, depending on how you contract it, broad heads to be seen. 768 (720) x576 (for me) on 16 / 9 right and left black bars (to have). I have then the whole picture, but without distortion!

SD PAL widescreen is smaller / less ", I assume, the studio is a visible Resolutionvon 720x576 INCL. black stripe above the bottom draw.
Your picture is therefore 720 (768) wide, which is 16 / 9 then about 432-480 high meant should.
If your television is intelligent, he fades from the black, and moves according to the film, but right then left rausfallen what needs to be given wider. (I think intelligently scan, or similar)

"(if I am on the text layer add text, appears as a red frame that somehow the size seems to be how the then visible on the Television Picture - whether's is a reference?)"

Exactly, the generator of Title Studio on the square, within which the title should be, is fairly sure that the title synonymous displayed on screen wird.Bei Röhrenfernsehern was the visible range.
Alternatively try PAL Progressive Wide, I have no experience with, but something will have changed between Pal and Pal-Wide-Wide-Pro.



Antwort von gtom:

Modern TVs have 16:9 in umpteen different screen modes.
How to implement the device is sometimes quite different especially since DVD Players synonymous nor interfere with the signal ... At the same settings produced PS11 at the same starting material (1 Clip MPEG2 PAL DVD-compliant) a 16:9 ZOOM Picture s.TV during Magix VDL as a small black bars above and below but showing s.TV WIDE. The same problem I have but synonymous with ARD and ZDF. On my TV / DVD equipment, I must always manually switch to the proper format to get ...



Antwort von holgerbgl:

Hi guys, good morning - thank you for your efforts & Answers!

I am very sure that I am in PAL widescreen took. Look at the screenshots.

I'm still irritated the red rectangle that when creating of my text is displayed. That is, what I afterwards to see the 16:9 television. 16:9 But on my laptop so I can see the whole picture (3rd screenshot).

How does that fit together because?

Antwort von holgerbgl:

I give as a preset PAL standard 4:3 that I see the following:



Antwort von Kunterbunt:

Ok, you PAL Wide aufnimmst I have not noticed, sorry!

What you at PAL 4 / 3 will see, is what I expect, because a PAL standard DVD is created, and you zoom your TV can bring, as a signal would get 768x576.
That was the idea, whatever, basically, whether or not Far Far material.
Workaround!
Have you ever lived with the two-Pal Far probiert options?








Antwort von holgerbgl:

"both" PAL-Wide Options?

I now try once the PAL standard version on the Television. Can only s.15.00 clock s.das device.

Sign me with the result. Bin gespannt.

In my S11 offers to new projects as PAL, PAL or PAL Progressive WIDE Wide open! Dito NTSC

Another remark:
PAL = 720x576
Widescreen PAL = PAL = 720x576, but the picture above and below cut off, and with streaks up to 576 again! "Gefäktest widescreen", so to speak.

That is why I refrained nehem in PAL synonymous incorporated in widescreen, same width in less Height of the image cut!

And since I do not know what kind of information onto a DVD Studio expresses eye, the PAL-or wide-called Progressive, is for comparison purposes (in my eyes) the Project to create 3x as PAL, PAL-FAR, and as far PAL Progressive (presumably there will be the player / widescreen monitor info to remove this black top can be cut off below, I do NOT!).
Then you know how it is presented, and how you can use it!
What does a. Avi in Pal Wide / Wide Proggressiv in relation to Pal (bars above / below)?

I wish you much luck, but you will not be experimenting around's drum rum come, unless you make in HD! Since the standard seems clearly defined!



Antwort von holgerbgl:

Okay, I am a 3 Compare this to create DVDs.

Avi in Progressive Wide:
the. avi is squashed to 4:3, that is all very thin ...

In the future, I take only in HD on - wanted to until now not because the studio was not yet processing.

Sign me with the result.

Suffers quality?

Theoretically yes, but ultimately it is so important, whether in practice plays a role and the losses are identified (in this case is not very likely).

... another problem: now I have the film finally on DVD. I watch it on my 16:9-Television s.and there is no right and left (and I believe synonymous top and bottom) Picture. The picture is totally bloated and now of course what is missing left and right.

Look into the setup menu of your DVD player. There must also specify that a 16:9-Television dranhängt. Currently, there is probably 4:3-Television and "Pan & Scan" for 16:9 DVDs. This is something the left and right away.

That the overall margins trimmed a little, it is for televisions, however, completely normal (called overscan).

"holgerbgl" wrote:

720 × 576 pixels are completely correct, synonymous if the arithmetically a 5:4-format would be (see 4:3 / 16:9 or 5:4?).



Antwort von Markus:

So, I have my answer



Antwort von WoWu:

Somehow I do not know how the two threads linked.
I have this phenomenon synonymous in the other thread says .... So somehow now twice .... you figure ....

The analogue PAL signal consists of frequencies, amplitudes and time slots and not from "Pixels" as is often erroneously assumed.

In ITU-R BT.601 will now determine how the signals in the digital world to be transferred.
After the digitalization of the 720 are slightly rectangular pixels then 702 square active pixels per line and 576 active lines per picture TV.
The 702 x 576 arise from the length of time (52¼s) times 13.5 MHz sampling rate.
Reinhartshausen analogy would be only 575 rows.
The 576te line results from the fact that there is a change in the fields 1 to 2 no half lines, as in the analog technology at line 313, which for the first half s.Ende Field and Field for the second half s.Anfang belongs.
It is sometimes called the speech of 575 lines and other times speaking of the 576th

If the pixels of the digitized signal PAL square, would a ratio of 702: 576 (approximately 1,22:1) arise.
This is in relation to the tube formats (4:3) rather narrow, because the converted are approximately 1,33:1.
Therefore, the pixels to such a screen to fill, slightly "wide format" his.
There are rectangles lying.
If now such a display on a computer monitor, which only works with square pixels, the picture would Portrait fail.
You have the picture that is in the horizontal stretch, and although by a factor of 1.094.
The result is 702 x 1.094 = 768 and thus the correct formats: 768:576 = 4:3.
The TV card of a computer must be on this format (768x576) to be set to a 4:3 TV picture to be able to show properly.
In the digital world has SD the TV picture horizontal Resolutionvon 720 instead of 702 pixels, because the horizontal Austastlücke the return of the cathode ray was removed and thus the presentation time at 53.22 microseconds can grow. Multiplying the back with the sampling frequency of 13.5 MHz, which yields the 720 samples or pixels per line for the Y-value. (Chroma, due (at) the 4:2:2 sub-sampling, only 6.75 MHz sampling frequency).
When comparing a formerly analog TV picture with a digital TV picture and we both tried to cover with photos, so you will find that the analogue Picture right and the left really 9 pixels are missing.
The horizontal elongation factor 768:702 = 1.094 from 720 square pixels of the digital component 788 square pixels in a computer, resulting in a picture results, which is 788:576 = 4,1:3 with only minor or imperceptible to 4:3 changes.
Generally you can say: When the relationship between pixels, eg 1280:720 result is a smooth, 16:9 here, it may be out of square pixels. The presentation of source material on the display would be the best can be transmitted.
If, however, a Krummer value, so it is "non-square pixels" and the presentation is often only after a quality conversion or scaling.
Depending Krummer the ratio is, the worse you may receive the image scaling and thus the display quality fails.
