Camera moves and motion paths can become quite advanced, especially with moves through 3D space. Harmony provides tools to view your camera’s path and make adjustments to it from both a 2D and 3D perspective.
You can display the trajectory of a motion path when you select an object from any view it can be selected in.
A motion path is easy to manipulate. One important concept to understand is that a trajectory contains both keyframes and control points. Both can be used to shape a path; each have their own behaviour, however only keyframes appear in the Timeline view.
- Keyframes have a transformation value and a position in space at a given frame. Keyframes are locked in time.
- Control points have a position but no fixed frame or timing. It is mainly used to deform a trajectory. There are no velocity handles available on a control point. The velocity segments are set between keyframes only, making curves and trajectories much smoother. Control points can only be added on a 3D path.
You can set the default Continuity, Bias and Tension parameters in the Preferences panel.
Continuity: Controls the smoothness of a transition between the segments joined by a point.
Tension: Controls how sharply the path bends as it passes through a control point or keyframe.
Bias: Controls the slope of the path so it flows towards one side of the motion point or the other.
