Dimensions

Right, firstly we're running at Pal 25 frames, timeline and rendering.

Out of Maya you want to be rendering at 1025 - 576.

And in After Effects you want to have a project setting of 720 - 576.
If i remember rightly Dan said that AE would recognise the ratio as widescreen and would automatically update itself. Either way its not something we immediately have to worry about, and we'll get him to confirm stuff before we make a start compositing.
