What is the purpose of the 'Set Matte' effect in After Effects?
Answer: Uses the channel of another layer as a transparency matte for the target layer
Set Matte lets you specify any layer in the comp as a matte source, giving more flexibility than Track Mattes.
What does 'Alpha Inverted Matte' do in the Track Matte options?
Answer: Uses the inverse of the matte layer's alpha channel to define transparency
Alpha Inverted Matte makes the layer visible where the matte layer is transparent and invisible where the matte is opaque.
Which render order principle means effects are applied BEFORE transformations in After Effects?
Answer: Effects process before the layer's Transform properties are applied
In After Effects, effects are applied to the layer source first, and then the layer's transform properties (position, scale, rotation) are applied.
What does the 'CC Composite' effect do when combined with other effects in After Effects?
Answer: Composites the original (pre-effect) layer with the post-effect result using a blend mode
CC Composite blends the original source of the layer with its effected version using any blending mode.
In After Effects, what is 'motion blur' simulating?
Answer: The blur caused by fast-moving objects during a camera's shutter open time
Motion blur replicates the smearing captured on film or sensor when an object moves faster than the camera's shutter speed.
What is the 'Shutter Angle' setting in After Effects composition settings used for?
Answer: Controls the amount of motion blur by simulating a film camera's shutter open angle
A larger Shutter Angle (up to 360°) produces more motion blur, while a smaller angle produces less.
