Sorrenson Squeeze HELP - I set MPEG2 as 720x480 btu QT shows as 640x480!!

Hello

I got specs from an agency to make our final spot an MPEG2 with the following specs:

Mpg2 muxed program stream
Mpg-2 (1 file containing both video and audio)
Video: 720 X 480, 5 - 8 mbps, 29.97 fps , color space 4:2:0
Audio: Mpg-1 Layer 2 : 192kbps , 48khz
Stream type: MPEG-2 MP@ML
Resolution: 720 x 480
Aspect ratio: 4:3 Generic
Framerate: 29.97
datarate : 5 - 8 mbps, that is bitrate: 5000000 - 8000000 Bit/Sec
Chroma format: 4:2:0, closed gop
Size : approx : 38 - 60 MB for 1 minute


The problem is that I set everything exactly as they have listed in squeeze and the resulting QT file comes out as 640x480 - is this because qt pro is displaying it in a weird way or am i actually setting something wrong - i set it to maintain aspect ratio as 720x480 so i dont see what i am doing wrong.

Please someone help i need to make this in the next 30 mins for client posting!!

Thanks

Lisa

You are doing nothing wrong.

720x480 is a non-square pixel resolution (for TV) - the square pixel resolution (for computers) is 640x480.
