Adobe After Effects Animation and Keyframes 2 — Questions and Answers
Question 1: What is the difference between 'Value Graph' and 'Speed Graph' in the Graph Editor?
- Value Graph shows the property's numeric value over time; Speed Graph shows the rate of change (Correct answer)
- Value Graph shows audio levels; Speed Graph shows frame rate
- Value Graph is for 2D; Speed Graph is for 3D layers
- Value Graph shows color values; Speed Graph shows opacity
Correct answer: Value Graph shows the property's numeric value over time; Speed Graph shows the rate of change
The Value Graph plots actual property values, while the Speed Graph plots how fast the value changes over time.
Question 2: Which roving keyframe behavior in After Effects ensures smooth constant-speed motion along a path?
- Rove Across Time (Correct answer)
- Auto Bezier
- Linear interpolation
- Hold keyframe
Correct answer: Rove Across Time
Roving keyframes adjust their timing automatically to maintain a constant speed along the motion path.
Question 3: What does pressing Shift while dragging a keyframe in the Timeline do?
- Snaps the keyframe to nearby keyframes or markers (Correct answer)
- Duplicates the keyframe
- Locks the keyframe in place
- Changes the keyframe interpolation to Hold
Correct answer: Snaps the keyframe to nearby keyframes or markers
Holding Shift while dragging a keyframe snaps it to other keyframes, markers, or the work area boundary.
Question 4: What is the function of the 'Anchor Point' property in After Effects animations?
- It defines the pivot point around which a layer rotates and scales (Correct answer)
- It locks the layer to a specific position in the composition
- It sets the starting frame for the layer
- It controls the opacity falloff of a layer
Correct 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.
Question 5: Which After Effects feature lets you record live property changes as keyframes while playing back the composition?
- Motion Sketch (Correct answer)
- Puppet Tool
- Graph Editor
- Wiggler
Correct answer: Motion Sketch
Motion Sketch records mouse or stylus movements and generates Position keyframes in real time.
Question 6: What is the shortcut to jump the Current Time Indicator to the next keyframe on a selected layer?
- K (Correct answer)
- J
- Page Down
- Right Arrow
Correct answer: K
K moves the CTI to the next visible keyframe on the selected layer(s).
