The following Alpha Adjust effect settings let you interpret the alpha channel in the clip:
Ignore Alpha
Ignores the alpha channel of the clip.
Invert Alpha
Reverses the transparency and opaque areas of the clip.
Blue Screen Key effect
The Blue Screen Key effect makes all image pixels that are similar to a standard bluescreen transparent.

Chroma Key effect
The Chroma Key effect keys out all image pixels that are similar to a specified key color. When you key out a color
value in a clip, that color or range of colors becomes transparent for the entire clip. Control the range of transparent
colors by adjusting the tolerance level. You can also feather the edges of the transparent area to create a smooth
transition between the transparent and opaque areas.
