Every clip with a video clip item, whether it’s a video, still image, or generator clip, has
the same motion parameters: scale, rotation, center, anchor point, and additional
attributes such as crop, distort, opacity, drop shadow, motion blur, and time remap
(speed). The Motion tab allows you to adjust these parameters of a clip.
You can create motion effects by setting keyframes for motion parameters over time.
For more information, see Volume III, Chapter 14, “Changing Motion Parameters.” Also
refer to Volume III, Chapter 15, “Adjusting Parameters for Keyframed Effects.”
