Disabling Animation While Playing
If you leave the Record button on, keyframes are added whenever you make adjustments.
If you want to restrict keyframing to when the project is not playing, you can disable that
feature individually.
To disable animation recording while playing
1 Choose Mark > Recording Options.
The Recording Options dialog appears.
2 Select “Don’t Record keyframes during playback.”
3 Click OK.
Recording Keyframes on Animated Parameters Only
When “Record keyframes on animated parameters only” is selected, 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).
2 Choose Mark > Recording Options (or press Option-A).
3 Select “Record keyframes on animated parameters only.”
4 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.
