By changing and adjusting keyframe interpolation, you gain precise control over the rate of changes in your transitions (or other effects).
Slows down the value changes entering a keyframe. You can manually adjust the handles.
Gradually accelerates the value changes leaving a keyframe. You can manually adjust the handles.
- LINEAR INTERPOLATION
Creates an evenly-paced change from one keyframe to another, with each in-between frame given an equal share of the changed value. Changes created with linear interpolation start and stop abruptly and develop at a constant rate between each pair of keyframes.
Tip: Setting and adjusting keyframes works in a similar way for video effects. Right-click on a clip and select “Show Clip Keyframes”. Set Keyframes with Pen Tool and adjust them with functions such as “Change / Move Video Keyframes” assigned to dials or wheel.
