Time pane
The Time pane of the Preferences window contains settings for how time is displayed in the
project, as well as for playback and keyframing options. There are three categories of controls:
Time Display, Playback Control, and Keyframing.
Time Display
These controls set how the time is counted in the Motion toolbar’s timing display.
•
Display Time As: A pop-up menu containing the following two items:
•
Frames: Shows incrementing frame numbers in the timing display.
•
Timecode: Shows eight-digit timecode numbers in the timing display.
•
Frame Numbering: A pop-up menu that sets whether frame counts begin at 0 or 1.
Playback Control
These settings control how Motion plays back your project.
•
Time View Updating: A pop-up menu that sets how the Timeline updates when you play a
project. Menu items include:
•
Don’t update: Prevents the Timeline from advancing as you play. This setting
improves performance.
•
Jump by pages: Sets the Timeline track area to jump forward when the playhead reaches the
far right side of the Timeline.
•
Scroll continuously: Sets the Timeline to scroll behind a static playhead.
•
If Audio Sync Is Lost: Buttons that set how Motion attempts to keep audio and video playback
in sync if the project is too complex to play both audio and video smoothly. Choose from one
of two options:
•
Skip video frames: Plays audio continuously but skips video frames to keep up.
•
Pause audio playback: Temporarily suspends audio playback when the project cannot
play smoothly.
•
Limit playback speed to project frame rate: A checkbox that, when selected, prevents the
playback rate from exceeding the frame rate of the project. By default, Motion plays back your
project as fast as possible based on the complexity of the effects and the processing power
of your computer. When this checkbox is deselected, playback rate is limited only by your
processor power; consequently, playback rate may exceed project frame rate.
