I want to edit together a series of interviews (talking heads) that were poorly shot by someone. I'd like to create a white background and have each talking head off either to screen left or right with a soft oval matte. So their face will be in the soft oval, and I can use the rest of the frame for titles, etc. So far, all I can create are square mattes in Boris FX. What's the best way to create a oval shaped matte? Thanks
The best way is probably to make the matte shape in photoshop (or similar) and import into Boris as a still image. Then place in the video's mask track as normal. If you can't make an alpha mask for your shape, make it 255 white on a 0 black backround and use "make alpha key" in the filters menu. You can then apply a Blur filter to get a soft edge.
Boris RED, (and perhaps later FX's/Graffitis) can generate spline primitives (circles, ovals, stars, rounded boxes etc) and allow you to draw shapes that can be used for very quick and effective masks.
