Keyframes are used to control or animate the difference between two values on a timeline. In the Animation Tool, you can add keyframe values to Pan, Tilt, and Field of View.
There are 2 keyframes to choose from: Keyframes and Magic Keyframes.
Move, Select, Copy, Stretch and Delete Keyframes
Once you’ve added keyframes, you can edit them:
To move a single keyframe do any of the following:
- Click to select it and drag it in the timeline.
- Drag the mouse around the keyframe to select it and move it in the timeline.
To move multiple keyframes do any of the following:
- Drag to select them all, and then click and drag.
- Select one keyframe, then Command-click or Control-click the other keyframes. Drag to move them.
To select keyframes, do any of the following:
- Click the keyframe in the timeline.
- Drag over keyframe or group of keyframes.
- Command-click the keyframes to select multiple.
To stretch/shorten a group of keyframes, do any of the following:
Select a group of keyframes, right-click on any of them and choose Stretch Keyframes. In the dialog, enter a percentage more than 100% to extend the keyframe’s length. Enter a percentage less than 100% to shorten the length.
Select a group of keyframes and press ALT and drag any of the selected keyframes.
To edit a keyframe’s value, do any of the following:
- Move the keyframe vertically in the Timeline.
- Right-click the keyframe and choose, Edit Value. Edit the value.
- Change the value in the track header and then click the Toggle Keyframe button to apply it to the current keyframe.

- Right-click on a keyframe(s) and choose Copy Keyframe from the menu.
- Select the keyframe(s) and press Command+C/Control+C, move the playhead, press Command+V/Control+V.
To delete keyframes, do any of the following:
- Place the playhead on a keyframe and use the Toggle Keyframe button in the Track or Toggle Keyframes button in the Keyframes section.
- Select one or more keyframes and press Delete.
- Right-click on a keyframe and choose Delete Keyframe from the menu.
There are four types of keyframes. Each will effect how the animation behaves. You can change the type by right-clicking and choosing from the context menu.
Linear Keyframe – There will be no acceleration or deceleration. The movement is constant.
Bezier Keyframe – This keyframe will create a slope with the keyframe acting like a corner. Use the handles on either side of the keyframe to modify the curves.
Continuous Keyframe – This keyframe is similar to the Bezier keyframe except that the curve will move through the keyframe in a straight line. To even out or smooth the slopes, open the context menu for that keyframe and choose Smooth Continuous Keyframe.
Hold Keyframe – A hold keyframe will hold the value. If the following keyframe is a different value, there will be a steep and quick change.
