What is a 'Track Matte' in After Effects?
Answer: A layer that controls the transparency of the layer directly below it
A Track Matte uses the luminance or alpha of one layer to determine the transparency of the layer beneath it in the stack.
What does the 'Collapse Transformations' switch do for a pre-composed layer?
Answer: Passes the pre-comp's transformations and frame size through to the parent composition
Collapse Transformations lets the parent comp 'see through' the pre-comp so transformations and frame sizes are inherited correctly.
Which blending mode makes black pixels transparent and white pixels fully opaque?
Answer: Screen
Screen blending mode inverts, multiplies, and inverts again, resulting in black areas becoming transparent.
What is a 'Pre-composition' (pre-comp) in After Effects?
Answer: A nested composition used as a single layer within another composition
Pre-composing groups selected layers into a new composition that appears as a single layer in the original timeline.
Which After Effects feature allows you to apply an effect to all layers in a composition without pre-composing?
Answer: Adjustment Layer
An Adjustment Layer applies its effects to all layers below it in the composition stack.
