Again me, another problem.

I'm using a pal dv video (720X576) and want to add a graphic as a background layer.

So I import a still picture from let's say photoshop in 720X576 pixels. When I rightklick that media and go to media properties, I have to set the aspect ratio to square, because it's a computer graphic. Otherwise it's horizontaly stretched.

If I do set to square it looks right, but doesn't fit the screen anymore... So my photoshop file has not to be 720X576. It must be more than 720 pixels.

What is the right aspect I have to use? What size has the graphic to be?

When I use 768X576 pixels and set it to square it is still one pixel (horizontal) to small. So you can still see a small stripe of the layer underneath.

If you just oversize the image, and then scale it down to fit your composition, you will aways be safe. Alternately, you could create the image in Photoshop using non-square pixels, so the pixel shape matches your footage.

Yeah, matching the pixel aspect ratio in Photoshop is probably the way to go here, that way you've got everything in the same format.
