[jitter] Blur edge of movies to black?

Hi there,

We've all seen it on photos where the outside of the image blurs/fades to black, well I'm now trying to do it to videos. I'm a bit of a beginner still on Jitter so go easy with me if its simple! I'm playing jit.qt.movie in colormode uyvy through a jit.gl.slab and then a jit.gl.videoplane. Preferably I would like to put the fading technique between the slab and the videoplane.

Does anyone have any idea how to do this? I would post my patch, but its far too big.

Cheers for any help,
Ben
