Frage von chri:
Hello everybody,
I have a very simple question. I have with my Panasonic NV-GS280 videos in 16:9 format made. These synonymous look to 16:9, when I look at it. But if I (in any program) at the videos on "Properties" go, appears to me that the videos would have a size of 720x576 px. However, if I enter into a calculator, here's 1.25 and not 1.777 ... raus.
I now understand the best will not. My specific problem is that I have videos that I made with a different camera, wants to scale that they have the same resolution (and the same format) as my Panasonic have videos. So I do not come next ...
I would be very grateful for a reply. It seems to me that it should actually have to be a totally trivial problem ...
Regards,
Christoph
Antwort von Lucky_Lucky:
Maybe just the fact that it liegts Auchter actually a video format is 720x576. It is only with black bars.
That's what many, if not almost all DV cameras Bereicht in the low budget. (and not only there, the XM2 or VX2100, as well!)
The above only make a "fake" 16:9 recording by shrinking the picture with black bars which then just as auschaut like 16:9 but just is not.
For the program but they belong just black bars just yet, but the video just so full of DV Aufloesung
Antwort von Axel:
Even "real" recording in 16:9 DV use only 720x576 pixels. You will then be interpreted only as broad. The loss of resolution is in Comparison to the letterbox version, but smaller.

Hi guest, hi Axel.
Danke schon mal.
On my camera is specially emphasized that it is "true" 16:9 images (ie where drübergelegt not just a black bar and thereby the effective Resolutionverringert is).
My specific question is: How big is it now the Resolutionbei my videos? 720x405 then yes it would be comfortable with black bars, right? But that is apparently not the case. How did the exact Resolutiondann?
What do you mean "broadly interpreted as" exactly? Perhaps it was added as 720x576 with a visual distortion (compression in the horizontal) and then later extended to numerically 1024x576 (scaled) is? Just a guess ...
If I look through a more detailed explanation.
Regards,
Christoph
Antwort von PowerMac:
16:9 in DV is always 720 times 576th It is stretched only when playing anamorphic. Your camera takes on real optical 16:9. The chip has probably an actual aspect ratio of 16:9. Only in the signal processing is the 16:9 picture squeezed to 4:3 electronical and so be saved. When editing the editing program you need only notify the anamorphic 16:9 DV material lies in the material. When playing equalizes the playing media such as DVD player or camera. PAL Pros synonymous works on a bruised signal.

Hello Christoph,
once you read through the following thread. He is not very long, but describes your concern and the solution quite well:

Bit of background: Digiknipsen or about LC monitor working with square pixels, say: This really means 16:9 pixels in the Height (576) times 1.78 = 1024. 4:3 then corresponds to 576 times 1.33 = 768.
PAL, NTSC (and many plasma screens) are working with rectangular pixels, PAL / NTSC 4:3 and 16:9, even with the same number of pixels, ie 480 times 720 or 576 times 720th States: For the display, the pixels are drawn differently in the Width or adapted to the screen grid.

Hmmm .... sounds to me a bit of chinese ...
So, if I now want to export my film (eg of.dv too. Mov), do I have if I want the same Resolutionbehalten to put the size of 1024x57? (For Panasonic 280; 16:9)
Thank's for feedback.
Antwort von PowerMac:
No, so synonymous?
Antwort von b.wildcat:
Then, of course, should be 1024x576 ....
"No, why synonymous?" - Heee??

Thank's for feedback. No.. The DV-AVI is 720x576, is noted in the file that the player they Resolutionals interpret 16:9, that is, in the Width to stretch.
When exporting to mov, these settings remain as such. The. Mov then so synonymous x 720 576 pixels and set a 16 / 9 flag, which tells the player that he should interpret the material 16 / 9.
That's what many, if not almost all DV cameras Bereicht in the low budget. (and not only there, the XM2 or VX2100, as well!)
This is not true. The XM2 offers an anamorphic picture, not a 4:3 picture with black bars on-screen.
Antwort von PowerMac:
At best, they provide an anamorphic picture, which corresponds to a 4:3 abgekaschten and scaled-Picture.

When I use to QuicktimePro of. To dv. Mov export, then I have no way to put such a "16 / 9 flag to. I can only determine the size. And if I set it to 1024x576, then I later got an easy line style (but of the correct dimensions) Picture. But if I put any dimension, then it is at least 4:3 and distorted in Quicktime format ...
Antwort von Meggs:

The picture is not wide-angle - ok that's true - is not a problem, the wide-angle optics is enough.
But it corresponds qualitatively well to the 4 / 3 Picture and is very good. I have included a play in the summer with 2 XM2 and 1 XL2 in 16 / 9. Who does not know, can not say the movie, of which camcorder is the scene.
Antwort von Meggs:

When I export a project in Premiere as Quicktime, I can specify more than the size of the synonymous Seitenverhöltnis of pixels. Default is selected while the aspect ratio of the project.
Antwort von Witti:
Who does not know, can not say the movie, of which camcorder is the scene. But only synonymous, because in any theater recordings because the quality of the light spikes soo suffering that always comes out slightly behind.
Almost no preference which camera you take ...

Almost no preference which camera you take ... Since I have made but quite a different experience. During daylight and good weather recording the differences between the camcorders are not so great for theater recordings already.
My result was good - the customer was thrilled. In previous productions I had it once with a Panasonic camcorder medium as 3rd Camera tries - the difference with the XM2's was huge - we have the 3rd Camera not used during the cutting.
Antwort von Witti:
Customers are enthusiastic for what quickly if they have no idea.
Another customer has left the tapes you have hewed to the ears.
But as I said, just in the LOW-light one can notice the differences between the cameras really are.
And the theater falls not so much because everything is somehow anyway botched ...

Another customer has left the tapes you have hewed to the ears. You're so funny - to judge shots that you've never seen.

What I said.
And the theater falls not so much because everything is somehow anyway botched ... Just ne questionable generalization above.

Hi, any solution found? I have exactly the same problem! And would be grateful for some tips!
Antwort von Andreas_Kiel:
When I use to QuicktimePro of. To dv. Mov export, then I have no way to put such a "16 / 9 flag to. Yet. See attached screenshot. The flag is set by you either "4:3 NTSC 720x576 or PAL 720x576 16:9 'dial. Screenshot just created with Quicktime pro.
