The keyframes interpolation can be changed and adjusted for more precise control over the rate of changes in your animations. You can choose either an interpolation type from a context menu or you can directly change one keyframe type to another by manually adjusting the keyframe or the handles.

The following interpolation methods are available in the keyframe context menu:

keyframe_context_menu

All keyframes are displayed on the Clip / Sequence Viewer screen and can be managed with the mouse.

Below are the illustrations of all interpolation methods applied to and effect parameter given as graphics representation on the Effect Editor timeline and in Clip Viewer.

Linear

linear

Linear is the basic interpolation method used in Effect Editor by default. It creates even transition from one keyframe to another.

linear_illustration

In the linear interpolation method, only the keyframes position is adjustable.

Bezier

bazier

Bezier interpolation method allows to manually adjust the shape of the motion graph with controls on both sides for modelling curves of a keyframe.

bazier_illustration

Special handles appear on both sides of a keyframe with this method of interpolation applied. Each of them can be adjusted independently.

example_1

Continuous Bezier

bazier

This method enables smooth transition between keyframes, where changing the graph shape on one side of a keyframe changes the shape on the other side to create a smooth curve.

bazier_continuous_illustration

Changing position of one of the handles will automatically move the other handle position so that they remain a continuous line, whereas their length can be changed individually.

example_2

Hold

hold

The hold method creates sharp transition from one keyframe to another to allow the sudden effect changes in a project.

hold_illustration

For a keyframe with this method applied, the motion graph looks as a horizontal straight line from the previous keyframe coordinates abruptly shifted to a specified position. The right-hand handle allows you to adjust transition to the next keyframe.
