Premiere Pro CS4 aspect ratio output stretched
Need help with Adobe Premiere Pro CS4 new aspect ratio issues. Widescreen output was fine in CS3 is now stretched in CS4 (too wide with black bars on top and bottom). It appears to me that I have the same settings so I am at a loss as to how (and where) to correct.
What I see in the program as I work on it is perfect 16:9 aspect ratio (as is in original footage shot in 16:9 widescreen).
The problem is on output (to Microsoft AVI). Need how and where to input exact settings to correct this in CS4.

If you want a perfect full frame in square pixels, change your resolution to 872×480 in your export settings.

How do I do that?

Ok, I figured out how to do the 872 x 480 but that raised new problems.
Yes, output is correct aspect ratio but the file size is now 16GB and takes a over 20 minutes to complete and when I play the 872 x 480 output video it is nearly in black and white.
Previously, my usual size for these 6-7 minute clips is about 1.5GB in Microsoft AVI format and take about 5 minutes with CS4 (but used to take half that time in CS3).
I never had these problems in CS3 as the output simply matched the source out-of-the-box.
Attached are screen shots of all I’ve tried and the results.
As you can see, the source file looks fine:
But the output shows this in the window and results in a stretched final .avi file (too wide):
These export settings look perfect in the export settings output window:
but as you can see the aspect ratio is off after output (too narrow):
:the change to 872 x 480 resulted in this (with a file size of 16GB!):
I hope someone here has an idea what is going on.
Thank you,

Ok, let’s rewind…
I didn’t realize that you were exporting in DV format. But now that I see screenshots…
You export HAS to 720×480, that’s DV specs.
Your original export settings (screenshot 2) should be DV widescreen PAR 1.2, it seems they were set to 0.9.
Screenshot 3 seems to be at the correct settings. Your problem is with the player you are using to playback the file (VLC?)
DV does not carry a flag like other files for aspect ratio, so you have to manually set VLC to play back in the correct aspect ratio, in that case 1.2.

You are correct. I hadn’t rechecked outside of vlc player. Thanks!

I don’t have any problems with WS flags in DV with a cam that has a WS mode unless I’ve used a cam with a amamorphic add-on lens then I have to adjust in the project for proper aspect

I should say the same “type of” flag.
Many media player miss that and end up playing squeezed.
