    Hello all,
    I am cutting a scene whereby the main character is driving a car at night.
    It is shot from the passenger seat across the car, his face is in profiler, his door window to his left as he drives is black.
    I have some archive shots of roads at night, lights, street signs etc that I would like to super impose onto the black window and would like to create a matte to do so.

    Can anyone give me some basic advise on how to do this.
    It is an offline edit so doesn’t have to be top spec, just a guide so any really basic help would be very much appreciated.

    Cheers,
    Dan.

    You can use the Animatte effect, under the Key category in the effects palette. Either image can be on the upper track, just draw your keyshape, for lack of a better term, and then choose “Key In” or “Key Out” till you get the effect you desire. With Animatte, you can create multiple key objects, move them independently, and you can feather the edges.

    Hi Scott,
    Does it matter which clip goes on which video layer?
    I put the archive on V 1 and the car window shot on V2 and swapped sources.

    In this case, no, just either swap sources or change the “key in, Key out” selection. It may make a difference in more complicated cases.
