Composite Modes use a clip's color, saturation, or lightness properties to create special effects and show clips beneath it. For example, a black and white image (known as a matte) can be easily cut out to allow video to show through the white (or black) portions of the matte.
Here is a more visual example:
Below is the image of a typical black and white image matte in the shape of a star.
Using composite modes, we can make the white portions of the image matte transparent and allow video to show through. You can see the star image matte's effect in the examples below.
Image mattes are very simple to create, however, I have included a zip file with 10 mattes that I've created for anyone to use. Examples of each matte are below.
