  • Anatomy of the Timeline

    The Timeline displays multiple video and audio tracks along a time axis (Figure 10.24 ). The base layers of video (V1) and audio (A1 and A2) appear toward the center of the Timeline window. Additional audio tracks extend below the base layer; additional video tracks stack above the base layer.

    Figure 10.24. An overview of the Timeline.

    If you have multiple sequences open, the Timeline and the Canvas display a tab for each sequence.

    Onscreen controls and displays

    Use the controls in the Timeline window to move the playhead, view the tracks in your edited sequence, and perform edits and keyframe adjustments. Timeline controls and displays include track icons, sequence edit points, and clip and sequence markers (Figures 10.25 ,

    10.26 , and

    10.27 ).

  • Current Timecode field: This field displays the timecode at the current position of the playhead. You can enter a time in the display to jump the playhead to that point in the clip. This display/control operates like the Current Timecode fields in the Viewer and the Canvas.

  • Render status bars: Customizing Final Cut Express" in Chapter 3.

    • Linked Selection control: The Linked Selection indicator controls whether linked selection is active or disabled. Note: This control toggles the Linked Selection feature, not Link/Unlink. One click on this tiny icon does not permanently unlink the linked clips in your sequence. You typically disable linked selection to select just the audio or video track of a linked AV clipto adjust a split edit in a sync sequence, for example.

    • Snapping control: Click to toggle snapping on and off.

    • Timeline track controls (Figure 10.26)

    • Track Visibility control: Click to make a track invisible. When the track is invisible, the contents remain in the Timeline but are not played or rendered with the sequence. Invisible tracks appear dimmed in the Timeline. Caution: Video render files can be lost if the track is made invisible.

    • Lock Track control: Lock a track to prevent any changes to its contents. Locked tracks are crosshatched in the Timeline.

    • Auto Select control: Use sequence In and Out points to define a selected area; then disable any tracks you want to exclude from your selection. You can cut, copy, search, delete, or ripple delete an auto-selected area. You can also apply copies of a filter to all the clips in an auto-selected area in a single operation.

    • Source and Destination controls for targeting tracks: Set the Source control to specify which source track is assigned to a destination track and whether the track is enabled to receive a source clip. The Destination control identifies the track. You can target one video target track plus one audio target track for each audio track in the source clip.

    • Audio Solo button: Click to mute playback of any other audio tracks, except those tracks where Solo is enabled.

    • Audio Mute button: Click to mute a track's audio playback.

    • Adjustable track height: Drag the lower border of any individual track to adjust its height.

    Timeline display controls (Figure 10.26)

    • Audio Controls button: Click to toggle the display of Mute and Solo buttons. Controls are hidden by default.

    • Clip Overlays control: Click to toggle the display of Audio Level line graphs over audio clips and Opacity Level line graphs in video clips.

    • Track Height control: Click to switch among the four track display sizes in the Timeline.

    • Track Layout menu control: Click the triangle to display a pop-up menu containing Timeline display options and to access saved custom track layouts.

    Timeline scaling and scrolling controls (Figure 10.26)

    • Center Zoom control: Click to jump between different time scale views.

    • Zoom slider: Use this slider to scroll through your sequence and to adjust the time scale of your view.

    • Vertical scroll bars: This two-part scroll bar allows the video and audio tracks to scroll independently. Adjust the thumb tabs between the scroll controls to create a static area in the center of the Timeline.

    Chapter 13, "Creating Transitions."

  • Locked track: A track whose contents cannot be moved or edited.

  • Opacity Level line graph: Adjust and apply keyframes to this editable overlay to set the opacity level of a video clip.

  • Audio Level line graph: Adjust and apply keyframes to this editable overlay to set the level of an audio clip.

    • Color coding in the Timeline

    Final Cut Express uses a color-coding system to identify the various clip and sequence types found in the Timeline.
