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.

Adding Keyframes

To add animation to an effect, move the timescale slider effect_editor_time_slider to the position where animation should start, and press the toggle_animation_button button. When pressed, the button turns into toggle_animation_button_pressed .

Ones a keyframe is added, it will be graphically represented on the Effect Editor timeline:

effect_keyframe_added

add_keyframe_button

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.

Deleting Keyframes

There are several ways to delete keyframes on the timeline.

remove_keyframe_button

Alternatively, you can use the "Delete" command from the selected keyframe context menu:
