Path Settings
Right knob (“Cont”): continuity (–4 to +4)
Spline Curve Settings
The following examples show how the keyframe interpolation path
changes as you adjust the spline curve parameters. In the figures,
the x- and y-axes represent the video image space, and the curve
shows the transition from keyframe 1 (KF1) to keyframe 4 (KF4).
Tension adjustment
• Tension = 0
The figure shows the incoming vector and outgoing vector
representing the path through the keyframe. Initially, both
vectors are parallel to a straight line joining the keyframe 1 and
keyframe 3 positions.
