Chapter 6 Keyframes and Curves 451
To disable animation recording while playing:
1 Choose Mark > Recording Options.
The Recording Options dialog appears.
2 Turn on “Don’t Record keyframes during playback.”
3 Click OK.
Recording Keyframes on Animated Parameters Only
When “Record keyframes on animated parameters only” is turned on, keyframes are
added only to parameters that are already animated. For example, if the position of a
shape is animated (keyframed) and “Record keyframes on animated parameters only” is
enabled, only changes made to the position of that object are keyframed. If you
change the color of the object over time, the color changes are not keyframed—even
when the Record button is enabled.
Important: The Record button must be on when using the “Record keyframes on
animated parameters only” option. You can still manually add keyframes, regardless of
whether or not Record is enabled, by using the Animation menu in the Inspector or
Keyframe Editor list, or by pressing Option+K.
Tip: If you are a Final Cut Pro user, it is recommended that you use this option to
emulate the workflow with which you are familiar.
To record keyframes on animated parameters only:
1 Enable Record (or press A).
1 Choose Mark > Recording Options (or press Option+A).
2 Turn on “Record keyframes on animated parameters only.”
3 Click OK.
Keyframes are now added only when you make changes to parameters that are already
animated. To observe how the “Record keyframes on animated parameters only” works,
walk through the following brief exercise.
To see the “Record keyframes on animated parameters
only” in action:
1 Enable Record (press A).
2 Choose Mark > Recording Options, and make sure “Record keyframes on animated
parameters only” in the Recording Options dialog is turned off, then click OK.
3 At frame 1 (press Home), draw a shape in the Canvas and move the object into a start
position.
A position keyframe is created.
4 Advance to a different frame and move the object into another position.
A second position keyframe is created.
