wow that's unduly complicated. There's no built in edge feather in Vegas?

There is, sort of. Making feathered boarders is really easy in Vegas... just use the built-in mask filter, run it out to the edge, then repeat for the other three edges. There's a feather slider right in the filter settings. I think there's a border tool too, but I don't remember if it has a feather slider. The mask approach is a bit slow to render, but it works great and is very easy.

A curved border, however, is going to take a bit of thought. It may be possible with the mask filter, if it will let me generate oval masks that are BIG enough... I fear that the maximum size is going to be to small to do it that way. So it may require building a mask externally. As ThrowgnCpr said, that's actually not particularly hard either. The hardest part may just be playing with it and verifying that it is good quality after encoding, that it doesn't get all jaggy.
