Timeline basics

Tracks

Video tracks (V1, V2 …) are stacked: higher tracks appear on top in the picture. Audio tracks (A1, A2 …) are mixed together. Add tracks with + Video / + Audio in the timeline toolbar. See Tracks: lock, hide, mute, solo.

The playhead

The red line shows the current time. Click or drag in the ruler to move it. The timecode on the left of the ruler shows its position.

Adding clips

• Drag from the Project panel or Source monitor onto a track. Hold ⌘ while dropping to insert (push later clips right) instead of overwrite.
• A video with sound becomes a linked pair: picture on a video track and sound on the matching audio track.

Overwrite behaviour

When a clip is moved or dropped on top of others, it replaces whatever is under it — clips underneath are trimmed or split, exactly like a professional editor.

Zoom and scroll

See Zooming and the zoom scroll bar.

Shortcuts show the Mac keys: on Windows and Linux use Ctrl for ⌘ and Alt for ⌥.
