Correct SAR for 4:3 720p?
Could you please tell me what is the correct SAR for 4:3 720p?
I have upscaled the Standard Definition video to 960 x 720 and I've added 160 pixels each to the left and right border to make a total of 1280 x 720.
For 720 x 480 4:3 I have a SAR of 8:9 and the video displays correctly but when I do the same thing for the 720p upscaled video, the picture doesn't appear wide enough - it's squashed.
I'm using the "ARS Calculator" program to give me the correct SAR. It works fine for standard definition but it doesn't seem to give the correct values for 4:3 720p.
