Frage von blenderman:


Hello together,

PAL 16:9 I have happily 1024x576 (square pixels) produces and then with the whole 720x576 (1.42) spent. Now I must read this actually 1050x576 (square pixels) is correct.

http://de.wikipedia.org/wiki/Phase_Alternating_Line#Digitales_PAL

If I have understood correctly, then this was a common mistake so far (eg Adobe CS3 to AfterFX wrong). It was the aspect ratio based on the calculated Height. It does not consider the width of 720 pixels only 702 are visible. Then it was either from the transmitter and the Picture squashed black is added per 9Pixel or the Picture has been emitted - but was slightly distorted.

True, but would have been the picture with 1050x576 (Square) for rendering and with 720x576 (1.46) extradite. The lack of the 18 showed 26 anamorphic pixels Square pixels. So 1024 +26 = 1050

Is it correct?



[update] 702x576 instead of 704x576 are correct. Posted revised.

Antwort von tommyb:

It is only right if it is DV.

If you create animations in 16:9 and then save as a DVD, then you can use it without any problems at 720x576 without runterskalieren edge.

Do you want to turn the whole than on DV tape off, then you need to scale it to 704x576 and left and right edges to add so that it is 720.

The aspect ratio of 16:9 is correctly 1.42222. This is roughly synonymous to HDTV. The aspect ratio of 16:9 DV is 1458 something.

Hello tommyb,

Many many thanks for your quick reply. Similarly, I had previously in the head. But if you look under Links times then you will see the Adobe, BBC and Wikipedia is not explicitly speak of DV. On passensten can I find the name of Wikipedia: Digital PAL

If a TV station files according to ITU-R BT 601 wishes. If I then, according to web 1050x576 -> 720x576 deliver. I see the Right?


Note
The aspect ratio remains at 16:9 always 1.42. The previously black area of 720 to 702 is now filled with information. 1050 & 1.46 requires an increase in the 702 range again to 1.42.
