Which shape operator in After Effects creates an animated dashed line effect on a stroke?
Answer: Dashes (added via the stroke's + button in the Timeline)
Adding Dashes to a stroke property lets you set dash length, gap length, and animate the offset to create a marching ants or moving dash effect.
Which feature lets text move along a custom path?
Answer: Path Options under Text properties
The Path Options in a text layer let characters follow a mask or shape path.
What is the function of the 'Anchor Point' property in After Effects animations?
Answer: It defines the pivot point around which a layer rotates and scales
The Anchor Point determines the center of rotation and scaling transformations for a layer.
What does the 'Time Remapping' feature allow?
Answer: Speed up, slow down, or reverse a layer's playback
Time Remapping keyframes a layer's internal time to alter its speed or direction.
What is Blur's opposite?
Answer: Sharpen
In image processing and visual effects, 'Sharpen' is the direct opposite of 'Blur.' While blur effects reduce detail and soften edges, sharpen effects enhance detail and increase contrast along edges, making an image appear crisper and more defined. Both are common image manipulation techniques used to adjust visual clarity.
Which panel lets you adjust the velocity and easing of keyframes with curves?
Answer: Graph Editor
The Graph Editor displays value and speed curves for fine-tuning keyframe interpolation.
What does the 'Enable Per-character 3D' option on a text layer do?
Answer: Converts each character into an individual 3D layer that can be positioned in 3D space
Per-character 3D breaks the text layer into individual characters, each behaving as a 3D layer with X, Y, and Z position.
Which of these effects can be applied to green screen footage?
Answer: Keylight
Keylight is a powerful and widely used keying effect in After Effects specifically designed for removing a solid color background, such as a green screen or blue screen, from footage. It accurately separates the foreground subject from the background, creating an alpha channel that allows the subject to be composited onto a new background. This effect is essential for professional chroma keying.
What property on footage would you allow to speed up one portion while slowing down another?
Answer: Time Remapping
Time Remapping is a powerful feature in After Effects that allows you to precisely control the playback speed of a layer over its duration. By setting keyframes, you can dynamically speed up, slow down, freeze, or even reverse specific sections of footage within a single layer. This provides flexible control over the timing and pacing of your animations.
What is the 'Threshold' effect used for in After Effects color work?
Answer: Converts an image to black and white based on a luminance threshold value
Threshold maps all pixels brighter than the threshold value to white and darker ones to black, creating a high-contrast silhouette.
What does enabling 'Collapse Transformations' on a pre-comp layer do?
Answer: Pass through transforms and preserve vector resolution
Collapse Transformations passes the nested comp's transforms upward and keeps vectors crisp.
Which interpolation type creates sharp, instant changes between keyframe values?
Answer: Hold
Hold interpolation keeps a value constant until the next keyframe, producing a sudden jump.
What does the 'Point of Interest' property on an After Effects camera do?
Answer: Defines the 3D point in space that the camera continuously aims at
Point of Interest keeps the camera always oriented toward a specific XYZ coordinate, even as the camera position moves.
Any effects or characteristics I need to animate or use?
Answer: Keyframes
Keyframes are essential markers on a timeline that define the start and end values of an animated property, such as position, scale, rotation, or opacity. By setting keyframes at different points in time, After Effects interpolates the values between them, creating smooth motion or changes over time. They are the fundamental building blocks for all animation in the software.
When you use 'Export > Add to Adobe Media Encoder Queue' in After Effects, what happens to the project?
Answer: A copy of the composition is queued in AME for rendering without locking After Effects
Sending to AME queues the composition for rendering in Adobe Media Encoder, leaving After Effects fully functional for continued work.
What is '32-bit per channel (float)' color mode in After Effects used for?
Answer: Enables HDR values above 1.0 and sub-zero values to preserve detail in bright highlights and compositing operations
32-bpc float mode allows pixel values beyond the standard 0–1 range, preventing clipping during compositing and enabling HDR workflows.
Which effect in After Effects allows you to replace all pixels of one color with a new color while controlling edge tolerance?
Answer: Change Color
Change Color isolates a hue range and remaps it to a new hue, with controls for similarity and match softness.
Which compositing method in After Effects allows you to re-light CG renders using normal pass buffers?
Answer: EXtractoR with multi-pass EXR files and relighting expressions
Multi-pass EXR workflows bring in normal, diffuse, and specular passes, enabling re-lighting in compositing.
Which tool would I use to change the anchor point of an object in the composition window?
Answer: Pan behind tool
The Pan Behind tool, also known as the Anchor Point tool, is specifically designed to reposition a layer's anchor point without moving the layer itself. The anchor point is crucial because it defines the center around which all transformations like rotation, scaling, and skewing occur. This tool allows for precise control over a layer's pivot point for animation.
What does the 'Material Options' property group on a 3D layer in After Effects control?
Answer: How the layer interacts with 3D lights, including its diffuse, specular, and reflective surface properties
Material Options lets you control Casts Shadows, Accepts Shadows, Ambient, Diffuse, Specular, and Shininess values for each 3D layer.
