the idea is to render to an AVI from Vegas and then take that into Boris. do whatever you want in Boris, then render an AVI to take back into Vegas. that would be the normal set of steps for using Vegas with other packages too. the only plugins out for VV3 right now are the ones from Pixelan and the ones from SoFo, so you typically have to render an AVI. search this board on 'Boris', because there are people who use Boris with Vegas and have posted methods.
