• Speed indicators: Speed indicators show you the speed of clips in your sequence using
tick marks. The spacing and color of these tick marks indicate the speed and playback
direction of your clips. The speed indicators of clips in the Timeline update in real time
as you make variable speed adjustments to clips in your sequence, showing you exactly
how you’re altering a clip’s timing. For more information about viewing speed indicators
while making speed changes to clips in a sequence, see
“Changing Clip Speed.”

Clip Keyframes control
• Clip Keyframes control: Click this button to display the keyframe graph area—additional
space below each video and audio track in which to view and edit keyframes for effects
that are applied to your clips.
• Clip Overlays control: Click this control to display opacity overlays (thin black lines) over
your video tracks, and audio level overlays (thin red lines) over any clips in the audio
tracks of the Timeline. These lines indicate video transparency or audio levels.
• Track Height control: Use this control to switch between four track display
sizes—Reduced, Small, Medium, and Large. The current setting is highlighted in blue
and has a small dot in the center. Choosing a track height with this control resets all
tracks to the new size, overriding any custom track heights previously selected. To
preserve the relative heights of individually sized tracks while resizing all tracks, hold
down the Option key while choosing a new height with this control.
Note: When the track size is set to Reduced, neither audio waveforms nor thumbnails
are displayed.
