Interpolating Camera Transitions

Interpolation functions can be added to the interval between key frames to smooth camera transitions, or to emphasize the beginning, middle, or end of a camera transition.

The following interpolation functions are available for camera transitions:

Interpolation functions
Item	Description
Linear	The following linear interpolations can be applied to create smooth camera transitions between selected key frames. Linear interpolation… Applies a linear interpolation between the key values of the selected interval. Smooth linear interpolation… Applies a smooth linear interpolation between the key values of the selected interval. Spherical linear interpolation… Applies a spherical linear interpolation between the key values of the selected interval.
Boolean	The following Boolean interpolations can be applied to emphasize the start, end, or middle of camera transitions between selected key frames. Focus on start value… Emphasizes the start value by producing an abrupt transition, from the start values to the end values, that occurs at the end of the interval. Focus on end value… Emphasizes the end value by producing an abrupt transition, from the start values to the end values, that occurs at the start of the interval. Bisection… Emphasizes the middle value by producing an abrupt transition, from the start values to the end values, that occurs at the midpoint of the interval.
Spline	The following spline interpolations can be applied to camera transitions between selected key frames. Cubic Bezier spline… Applies a Cubic-Bezier spline interpolation between the key values of the selected interval. Catmull-Rom spline… Applies a Catmull-Rom spline interpolation between the key values of the selected interval. Spherical cubic interpolation… Applies a spherical cubic spline interpolation between the key values of the selected interval.

See Working in Advanced Mode for information about adding interpolation functions to other key value transitions, such as opacity, lighting effects, and gradients.

You cannot add a camera interpolation to the interval between a camera rotation. Key frames linked by a rotation are indicated as such (see Adding Rotations).
