Hi, Uwe,

I just sent you a clip and am curious to see how it plays.

When I went back to Adobe Media Encoder, I noticed an interesting 
thing about the PAR setting there. You don't actually set the pixel 
aspect ratio, you set the screen aspect ratio and the encoder 
automatically sets the PAR according to your frame width and height 
so that your final result as the screen aspect ratio you specified. 
So when I specify 1440x1080 pixels resolution and a PAR of Widescreen 
16:9, the encoder sets a PAR of 1.33:1 when it encodes.

I can't find a program that displays what a video file's PAR is. WMV 
and VLC Media Player both interpret PAR correctly, but when you look 
at the codec properties (available only in VLC), it shows only the 
dimensions of 1440x1080, not the PAR or the screen aspect ratio. It 
would be interesting to know how PAR is embedded in an mp4 file and 
how players interpret it.
