track matte

In QuickTime, a pixel map that defines the blending of track visual data. The value of each pixel in the pixel map governs the relative intensity of the track data for the corresponding pixel in the result image. QuickTime applies the track matte, along with the track clipping region, to the image contained in the track rectangle to obtain the track boundary region. See track boundary region, track matte, track rectangle.
