Fullscreen Aspect ratio

[tominator]

Hi
I have an avi-file which has a resolution of 720x576 which would lead me to believe its AR is 1,25:1.

Since I encode to WMV 640 width this means the height should be 512.

The problem here is that when in fullscreen the video gets letterboxing on right and left.

How can I prevent this?

Crop the hieght to 4:3 DAR. 640 / 4 x 3 = 480.
(512 - 480) / 2 = 16 pixels from top and bottom.

Cheers.

What exactly did you expect when you forced a 1.25:1 AR? You can either proceed as Skelsgard suggested, or convert it using a 1.33:1 AR and see if it looks proper (i. e. something that should be spherical is still round in the final file).

Without seeing a still from your 720x576 source I would suggest that if you add either 4:3 or 16:9 aspect ratio signalling to your 720x576 PAL source, it will be displayed at an anamorphic resolution equating to either 768x576 or 1024x576 pixels!
