Fit/Scroll in Timeline
After you have resized your workspace to your liking or added additional PiP or music tracks to the timeline using the Track Manager, click on the button so that all tracks are displayed within the existing timeline. This ensures that you don’t need to scroll to view certain tracks.
Click the button for a larger display of the tracks in the timeline, and enable scrolling up and down in the timeline.
Note: when scrolling is enabled within the timeline, the Master Video Track will always remain on top of the other tracks when scrolling through the tracks.
