Use keyframes to transform the state of a grade, mask, or pan-and-scan adjustment over time. A keyframe marks the point in time where you specify a state, such as the position of a mask. You typically use at least two keyframes—one for the state at the beginning of the change, and one for the new state at the end of the change. You can add as many keyframes as you need on a track. SpeedGrade interpolates the values between keyframes and creates dissolves between them.
Every new grading track has one keyframe at its start position. If you don’t add more keyframes, any adjustments affect the whole clip.
To add more keyframes along a track:
With the playhead at the current keyframe, click the Record Keyframe button a second time to create a dissolve from the previous keyframe to the current keyframe. See Workflow for creating dissolves between keyframes.
An arrow between the keyframes on the track indicates a linear dissolve between the two positions.
Create a dissolve between two keyframes by clicking the Record Keyframe button a second time at each new keyframe position. The typical workflow is as follows:
When Auto-keyframe mode is on, modifying a property automatically adds a keyframe at each new position.
