Automatically Adding Tracks to Your Sequence While Dragging

You can drag a source clip to the unused space above or below the current tracks to create a new track for that clip. If you drag your clip above the tracks already in the Timeline, you’ll create a new video track. If you drag your clips below the tracks in the Timeline, you’ll create a new audio track.

Clips with both audio and video clip items create both kinds of tracks by default, unless either the video or audio Source and Destination controls are disconnected.

When you drag a source clip to a track in the Timeline, all the clip’s items are linked. The track you drag a clip to always receives a clip item, regardless of whether its Source and Destination controls are connected. However, additional clip items are only placed on tracks whose Source and Destination controls are connected.

For example, suppose you have a clip that contains a video clip item and two audio clip items. If you drag that clip to a video track in the Timeline, the video clip item is placed in the video track, even if the Source and Destination controls for the video track are disconnected. Each audio clip item is placed in the corresponding Timeline audio tracks, but only if the Source and Destination controls of those audio tracks are connected.

If you connect nonadjacent Source and Destination controls, the source clip items are edited into the sequence using the track separation defined by the Source controls. For example, if audio tracks A1 and A3 are the current audio destination tracks, a clip that you drag to the Timeline will always have one empty track between the two source audio clip items, and will keep that one-track offset no matter which audio tracks you place the items into.
