Frage von MBN:
Hi,
I have long with the different aspect ratios and pixel sizes rumgequält. Well I finally thought I had done it, but to me is the difference between 704 and 720 pixel still not clear!
Used when capturing the horizontal resolution is fairly no preference, which can be synonymous only 352 pixels, the number of lines should always be 576! The prerequisite is that when playing back in the correct aspect ratio is adjusted.
DV returns now always 720x576 pixels, analog capture cards can deliver pretty much everything, synonymous 704x576!
Sometimes I see DV recordings that have 704 pixels, and the left and right 8 Black pixels include, in order to come to 720.
The
display in 4:3 with square pixels and 576 lines is
768x576 pixels, at 16:9, square pixels and 576 lines, it is
1024x576 pixels. A television is an analog PAL signal in 2 is possible Breiten-/Höhen-Verhältnissen: 16:9 and 4:3.
Now the big questions:
- How do I have a PC at 720x576 pixel size images equalize? To 768? Even if only 704 with a black edge drinstecken?
- How do I have 704 pixel wide images equalize? Also to 768? That would be correct if it is just next would be squashed. Or is it just trimmed?
- What makes a DVD player, if he spends such material analogy?
Please help me! I do not like distorted images.
Greeting
Alex

16:9 and 4:3 are always 720 x 576 pixels, the DVD player Staucht the Height of the Picture in the right proportions and the High Resolutionerreicht will.
