Thanks for the input everybody, I've got everything under control. This is what I've learned:

Nothing in the encoded video changes when you change the pixel aspect ratio... it's kind of like setting a flag saying "please display me with a .900 pixel aspect ratio." I say this because upon changing the setting in premiere of a .900 ENCODED clip to square, it just changed it on the fly and it was back to normal, EXACTLY as it had been before. Also, I'm not sure that programs such as virtual dub even recognize the pixel aspect ratio flag... I compared the in-program size of two 720x480 clips, one supposedly encoded with a .900 pixel aspect ratio and the other with square pixels, and they were both identical in size, both before and after encoding to divx. I hope this helps somebody

oh... and if you have a bunch of clips to change from .900 to 1.000 in premiere, just repeat this keystroke combination:

<alt>cnp<down><up><enter><enter><down>

you could also plug this into a macro program and have it repeat the keystrokes for you while you go have some ice cream.

Well actually if you set your project to 0.9 pixels, it resizes your video to 648x480. The thing that I was thinking could possibly cause a issue that you would not notice is if you have a clip set for 0.9pixels, but your project is @ 1.0 pixels. Premiere would Resize your 720x480 source to 648x480, then back again to 720x480. Which could cause distortion or artifacts to show up.

The thing is that if it looks fine, then it probably is fine.

Yeah... I noticed that whenever I exported something, the little window that came up to display the video or bmp was in 648x480, but when i imported THAT file it was back to 720x480 .900. Like you said, probably because of my project settings. but... there are no artifacts or distortion anywhere, and everything is exactly as it used to be.

The reason is was back to 720x480 is because you exported like so

Video Settings and Export Settings are separate from each other...

You could make a video thatis' 320x240, but when you goto export it change settings so that it exports at 720x480(though it'd be a bad idea).

There isn't a 'pixel aspect ratio' tag included with AVIs. All premiere does is mash the horizontal resolution..

so if i have the project settings as square and the export settings at square and the clip settings at .900, what happens when i export? if i export it like that, when it launches the video after the encode is finished, its 648x480, but other programs read that as 720x480. my monitor in premiere is 720x480...

Yes, it's all so confusing

When Premiere opens it up after it's done encoding, it doesn't even remember what the file is for, it just opens it and does it's default 0.9 pixels on it.....because it's evil...

Iam tired of explaining it

If it looks good, I'd leave it
