Control speed between keyframes without using the speed graph
• In the Composition or Layer panel, adjust the spatial distance between two keyframes on the motion path. Increase
speed by moving one keyframe position farther away from the other, or decrease speed by moving one keyframe
position closer to the other.
More spatial distance between keyframes increases layer speed.
• In layer bar mode or in the Graph Editor, adjust the time difference between two keyframes. Decrease speed by
moving one keyframe farther away from the other, or increase speed by moving one keyframe closer to the other.
