Effect Editor supports making effects added to a clip animated with the help of keyframes. A keyframe is a frame in which a change of an effect parameter is defined. To create a simple animation, at least two keyframes are needed – one for the initial parameter value, and another one for the new value. The parameter values between two keyframes are interpolated, i.e. automatically calculated to be distributed along the span. By default, this distribution is an even span. For more elaborated animations you can add extra keyframes between the start and end keyframes.
To add animation to an effect, move the timescale slider to the position where animation should start, and press the button. When pressed, the button turns into .
Ones a keyframe is added, it will be graphically represented on the Effect Editor timeline:
It is possible to add multiple keyframes for animation to take effect. Reposition the slider to a different location on the timeline and press the "Add/Remove Keyframe" button.
The "Add/Remove Keyframe" button displayed in blue means that an existing keyframe is currently selected.
Press the "Go to Previous Keyframe" button to select the previous keyframe on the timeline.
Press the "Go to Next Keyframe" button to select the next keyframe on the timeline.
There are several ways to delete keyframes on the timeline.
Select the required keyframe on the timeline and press the "Add/Remove Keyframe" button.
Alternatively, you can use the "Delete" command from the selected keyframe context menu:
All keyframes for a certain effect parameter can be deleted deleted simultaneously by pressing the button. The following warning massage will ask you to confirm the keyframes deletion:
Manipulating Keyframes on Timeline
The added keyframes can be manipulated directly on the timeline. They use the following table explains the keyframes indication and coloring:

The keyframe animation ends with
The keyframe in the middle of animation
The selected keyframe
Points indicating the keyframe position on the X and Y axes
You can drag-and-drop the points on X and Y axes up and down directly on the timeline to change the keyframe position.
