Timeline

Tracks

Video and audio clips sit on separate tracks. Add a track with +V or +A, and change its height with Alt and the mouse wheel.

Track menu

To open this menu, right-click a track name or press T. Remove track also removes the clips on the track, and the last video track always stays.

Add clips

A file you drop on the timeline lands on the track and time where you drop it, and overwrites the clips it covers. A video with sound also adds one audio clip for each of its audio tracks, and an image lasts 5 seconds.

To swap the file of a clip, choose Replace in the clip menu. The clip keeps its place, its cuts and its settings.

Move clips

Drag a clip to move it, even to another track. It stops at the next clip unless you hold Ctrl, which lets it overwrite the clips that it covers. Hold Alt to move the video and the audio of a file apart.

Snapping

With snapping on, the edge of a clip sticks to the playhead, to the start of the timeline and to the edges of other clips. N turns it on or off, and Shift flips it for one drag.

Trim

Drag an edge of a clip, or move the playhead to where the clip should start or end and press I or O. X restores the full length.

When two clips touch, the next clip follows the edge. Hold Alt to trim only one clip.

Split

Split cuts every clip under the playhead in two. Each part is a clip of its own, so it can have its own settings.

Remove and ripple delete

Delete removes the selected clips and leaves a gap. Shift Delete is a ripple delete, which also closes the gap. If you use ripple delete more often, Ripple delete by default in Settings swaps the two keys.

To close a gap later, right-click it and choose Ripple delete. Edit > Close gaps closes all of them at once.

Clip speed

Right-click a clip to change its speed, from 0.13x to 8x. With interpolation on, a slowed clip becomes smooth slow motion, because interpolation adds the frames that it lacks.

For an audio clip, Gain in the same menu changes the volume, from -24 dB to +24 dB.

Fades and crossfades

Drag a top corner of a clip to fade it in or out, for up to 5 seconds. To choose the curve of a fade, right-click near that edge of the clip. To set a crossfade, right-click between two clips that touch.
