When you want a layer to appear through a hole defined by another layer, set a track matte. For example, you can use the text layer as an Alpha matte for the video layer, allowing the video to show only through the shapes defined by the text characters. The underlying layer (the filler layer) gets its transparency value from the values of some channels in the track matte layer — either its alpha channel or its pixel light.
When you want to create a matte using a layer without an alpha channel or a layer imported from a program that cannot create an alpha channel, the transparency of a layer based on the luminance of the pixels of the track matte It is useful to define. In both cases – using alpha channel mattes and using luminance mats with higher values – are more transparent. Typically, you use a high-contrast matte so that the area is either completely transparent or completely opaque. Intermediate shades should only look where you want partial or gradual transparency, such as soft edges.
