i imported an avi movie to vegas.
the movie has a solid black backgroung.
is there a way to make it trasnparent , so the layer i put under it could be seen?
thank's
Use the chroma key, then use the eyedropper tool to select the black color of the video you want to be transparent and that should do it. If there is any other part of the video that has the same black color that will also become tranparent so this trick might not work as well as you hope.
