Modifying a Path in the Camera, Top and Side Views

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 in the Timeline or Camera view.

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 significance and 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.

When you select a control point on a path, you can switch between a rounded or square corner by using the Linear/Curve command.
