Toggling Animation

Reading time ~2 minutes

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 elaborate 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 the animation should start, and press the toggle_animation_button button. When pressed, the button turns into toggle_animation_button_pressed .

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

add_keyframe_button

It is possible to add multiple keyframes for the animation to take effect. Reposition the slider to a different location on the timeline and press the "Add/Remove Keyframe" button.

remove_keyframe_button

The "Add/Remove Keyframe" button displayed in blue means that an existing keyframe is currently selected.

previous_keyframe_button

Press the "Go to Previous Keyframe" button to select the previous keyframe on the timeline.

next_keyframe_button

Press the "Go to Next Keyframe" button to select the next keyframe on the timeline.

Tip	You can use the key combinations `Shift`+`Delete` to cut, `Ctrl`+`Insert` to copy and `Shift`+`Insert` to paste the selected keyframe.

Deleting Keyframes

There are several ways to delete keyframes on the timeline.

remove_keyframe_button

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 simultaneously by pressing the toggle_animation_button_pressed button. You will be asked to confirm the keyframes deletion in the following warning message:

Manipulating Keyframes on Timeline

The added keyframes can be manipulated directly on the timeline. In the following table the use of the keyframes indication and coloring is explained:
