so have a pretty basic question about how to setup content for an intended edge blending setup.

first of does anyone have an opinion on an optimum percentage of overlap? 10%? 25%

does catalyst put the feathered transparency in or do i do that in after effects?

it is as basic as i think right? meaning if you are going to stitch two projectors running 1024x768 then i create two pieces of video which have the same exact content in the shared 102 pixel overlap region (10% overlap)

any advice would be greatly appreciated.
