Delete a track on the timeline
Tracks represent the sequence of all media within a video. Camtasia allows you to create an unlimited number of tracks. You may want to delete tracks when you have a blank track after moving media between tracks or if you have extra tracks on the timeline.
To delete a track
Control-click to the left of the track to delete.
Select Delete Track. If there is any media on the track a message will appear asking if you want to delete the track and all media on the track.
