Hello when I with my DV Cam 16:9 movies and then in the after-effect is to invite the Picture is not directly stretched. So I wechel view in 16:9. Settings do I to PAL 16:9 widescreen (1.42) A.
If I export the file and now all set to leave like (Voll, Best Quality, 720x576), interprets the VLC and Windows Media Player, not the 16:9.
What should I know how to adjust?

Square pixels take composition. Computer without any additional pixels are always square Entstauchungsmassnahmen.

or simply the amazing butter (Pixel Aspect Ratio Correction) under the preview monitor to simulate the press of the pixel aspect ratio

PAL now has even the 720x576 ratio. is 4:3. 16:9 in this format can only be through a letterbox erziehlt be (video shrink balken are) or you can start the beginning of s.ein anamorphic project if it is "true" 16:9 is: So the camera's native 16:9 chip has. pal anamorph has dimensions 1024x720. I would recommend: pal preset and then change resolution to 720x400, then it fits wonderfully, and saves disk space, not too much pixel-expected.

Wrong! Zieh times the rate calculator.

Re wrong. Anamorphic pal has 720 x 576 pixels and is displayed at 1024 x 576 pixels.

Again false. Calculators!
The export in 720 x 576 16:9 reduces the resolution and not working. An export in 720 x 405 square pixels and works synonymous, but the reduced resolution. An Export in 1024 x 576 pixels and quadratic functions, reduces the resolution is not increased but the exported file with no visible gain.
After Effects recognize 16:9 clips correctly. The button below the monitor, the clip is synonymous correctly. When exporting you have to get the aspect ratio explicitly. If you eg DVPal and select 16:9, the exported AVI in Media Player synonymous correctly displayed. In the VLC player, however, not because the DV-Avis at the aspect ratio is ignored.

PAL is an analog signal and has no pixels, but it consists of frequencies, intervals and amplitudes. At best, you could call them dots .... and not 720 but 768 (4:3). Copies now the signal in the digital world, one has at best a SD signal, but no more PAL. But pixels and a choice of two formats: "square pixel" (768x576) or "non-square pixels" according to ITU-R BT.601 (720x576 / 5:4). Using this format, following the digitalization of the 720 slightly rectangular pixels then 702 square pixels per active line. 702 The result from the length of time (52¼s) times 13.5 MHz sampling rate. You have the picture that is in the horizontal for a correct image 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. 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. Strictly speaking, it is not really 4:3, because it compares a formerly analog TV picture with a digital TV picture and we both tried to cover with photos, so you will notice that the right analog and Picture Links 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 synonymous if only slightly differs of 4:3.

I think it's great what you all know, and how well you are familiar. But here we went to After Effects and DV, not analog Pal. Even in the digital world, the term appears PAL to distinction as to NTSC. Adobe used in the export settings in After Effects the term DV PAL. Even with standard definition digital camcorders is made between PAL and NTSC models.

Eben, therefore synonymous my objection, because there is no analog pixel.
Unfortunately the terms are always used, but by repeating false names, they are far from being true. PAL is and will remain analog, NTSC, as well as synonymous when you have so many false leads applications. Time, quite apart from the NTSC that in most cases anyway no longer true, unless we are talking about a 20-year-old signal, because of ATSC NTSC is in the digital domain since been replaced. You need the truth always repeat the mistake because synonymous forth to us again and again is preached, and not of individuals but of the mass. Of Johann Wolfgang Goethe
Because it is here in the forum but not limited to professionals like yourself, it is even more important, the correct meaning to use. But it remains to you of course free to continue to digital and analog after Gusto names to use. But in the manufacturer's descriptions are not only correct information ... unfortunately. Nothing for ungut.

Greets you, I rise to your forum and am just with a problem in FinalCut. We have an animation created in After Effects (composition: PalD1 / DV 16:9 quadPixel 1024/576) and this without the video Loseless Picture raus rendered. The Alpha in FinalCut activated and placed on the video. The width fits we have real 16zu9 Height rotated but does not fit! top and bottom missing. In FinalCut I 720mal576 original material in this and the animation as the 1024mal576 Width Height agrees but not! I did try some but as yet no success. Regards, Janis

What are the sources of the original material? Digital 4:3 material or was it originally analogue material times? (see above)
Antwort von janirolling:
Hello WoWu, and all other Grüß I hereby synonymous *
Analog of Band_ Ausgespielt by Cutter on DV tape. 16zu9 real. digitized with the recording settings 48khz DV Pal Anamorphic Result: Bidmaterial with Compressor: DV Pal; Image Size 720mal576 then: sequence creates DV Pal Anamorphic 16zu9
At this point (I just discovered) is between the video material and the sequence in which I've pulled it inside a small difference in the information: the sequence for After Effects, I've been rausgerendert of the pixel arrangement on Square set. I will now on DV Pal set out to render in after effects to import into the kompositon get inside and see if it is because the animation is not the correct Height has.
To be honest, I understand this whole pixel arrangement is not really history.
Habs right now and tried on the first glance nothing has changed, the Kompositonseinstellung in AE were PalD1 / DV 16:9 quad. Pixels, height 1024 width 576; pixel aspect ratio: square pixels.
If I change in the composition PalD1 / DV 16:; width 720 height 576; pixel aspect ratio: D1 / DV widescreen (1.42) then it makes my staucht Picture together on a 4:3 picture, somewhere it is not true here. ?
screenshot, shame they've added as an attachment try it again.

I habs to Kompositonseinstellung in PalD1 AE / DV 16:9 quad. Pixels, height 1024 width 576; pixel aspect ratio: square pixels. are in order.
that's it ... Incorrect sequence was set in FinalCut: Pixel arrangement on Square. Now on Dv-Pal fits.
But what surprised me, despite everything, I import the file into FinalCut Animationer and the pixel layout is square. Although everything else on DV Pal stands.
As they say ... I know that I know nothing!
Knowledge is power! But try it out:) he he
Thank you WoWu you have me on the right track *
Love of Janis
Antwort von WoWu:
Hello Janis ...
I am pleased that it went well. The pixels are also slightly elongated, the elongation factor of above 1.094. If I now picture of 788 horizontal adjust missing part of me naturally vertically. But ... had calmed down, one day, we have only to do with 16:9. Whether we still are experiencing is more doubtful. Best Regards
