Question

Two difference between Timeline and Video Preview Window.​

Answer 1

Switching between Timeline views

Two types of views are available in the Timeline: Storyboard View and Timeline View.

Storyboard View

The fastest and simplest way to organize photos and video clips in a project is to use the Storyboard View. Each thumbnail in the storyboard represents a photo, video clip, or a transition. Thumbnails are shown in the order in which they appear in your project, and you can drag thumbnails to rearrange them. The duration of each clip is shown at the bottom of each thumbnail. In addition, you can insert transitions between video clips, and you can trim a selected video clip in the Preview Window.
