The Timeline view is where you assemble the timing of a scene’s visuals and sounds. You can add sound track layers, as well as edit audio files imported into the sound tracks. You can also add transitions and control the playback of a selected panel or the entire storyboard from this view.
By default, timecode format is used to display the timing in the most accurate manner. The starting timecode of your project is set to 00:00:00.00. However, sometimes it may be best to use the number of frames as a timing value and a later timecode value as the start of your project. You can modify the format and default starting time code value via the Preference dialog box.
