I am working on UFOCaptureV2, but I do not have PAL equipments,so please teach me about PAL 720x576.
Is true aspect ratio(which means true square pixel) is 720:576 = 5:4 ?
or it needs some interpolation?
(The aspect ratio of NTSC-IEEE1394 720x480 is 4:3 and needs to reduce 640x480) |

Hi Robert
Thank you for detail explanations and example links.
Wow... it is a little more complicated than I expected.
720x12:576x11 = 15:11 = 4.09:3 (!= 4:3)
Now, I think I will make V2 programs as follows.
User can set both input video size(Xi,Yi) and output video size(Xo,Yo) freely.
If both size are equal, no interpolation would be done.
(UFOAnalyzer can handle any pixels ratio)
If user set Xi,Yi = 720x576 and Xo,Yo = 768x576, user can get square pixel images and videos. |
