Why doen't QT Player show 16:9 Aspect?

I'm converting some DVD WS video to QT for a client.

I'm using a 3mbps preset, keeping frame size at 720 x 576, and making sure aspect ratio is set at 1.457

However when I play it back with QT player (7.2), it shows as 4:3 and everyone is squished tall and thin.

Even when I put the .mov clip on the Vegas timeline, it displays as 4:3 until I change aspect ratio to 1.4568 in properties.

Haven't these Mac people heard of widescreen?

Good question. I dont know either. But for sure it is something about the settings QT not streching out the anamophic pixels, or the version of QT player. It is the same for me. I do commersials for TV. I finalize everything in Vegas in 16:9, then render to QT, then check the results in QT or on the Vegas timeline. Widescreen is now narrowscreen 4:3, terrible looking. Then I send the file to the TV companies buying it. They put it into their mashine, I sit down and turn on the TV at home, and on television the commersial is shown in perfect widescreen again.
Anyone else have a good explanation?

I can't explain it but when in doubt I use square pixels. Hard for anything to mess that up.

Even QT renders using QT Pro don't show the aspect correctly.

I chalk it up to QT implementation on the Windows box, and call it a "feature".

I do get QT player to show a 720x576 DV wide in a 16:9 format by going to 'Show Movie Properties' (Ctrl+J)-> tab 'presentation' , then clic 'Conform aperture to' and select 'Production Aperture'...
It certainly should be automatic, but meanwhile this workaround might also help you.

QT player (in Windows, anyway) doesn't respect PAR, so you have to render at 16:9 (square pixels), for example.

So, 1440x1080 at 1.3333 becomes 1920x1080 at 1.0.
You do the math that fits your SAR best. HTH
