before the last forum crashed there was a talk about making graphics 
in photoshop 640x480, or 720x480....ive done some further testing and 
to my surprise heres what i found...

1..if i create a perfect circle in photoshop and bring into premiere
heres what happens

720x480= on tv screen circle measures 9.5 wide by 9 7/8 tall...
640x480= on tv screen circle measures 10 1/8 wide by 9 5/8 tall...

neither are no longer a circle but oval, AM I SURPRISED!!
turning on maintain aspect ratio still does not create perfect 
circle...so what is the correct size in maintaining height x width?

Looks like it ought to happen at 684X480 according to your measurements.

Here's how we do it.

Create your circle in a 640 x 480 image workspace. Once everything 
is created, change the image dimensions to 720 x 480. The circle will 
look oval on the computer screen at this point, BUT, when you bring the 
image into your timeline, it will output to NTSC with proper aspect ratio.

Hope this helps,
