Saving a track as an alpha channel video
Alpha channel video supports transparency, allowing you to save animated logos, lower-
third graphics, and other objects and animations as video files that you can share and reuse
as overlays in other video projects. For example, if you create a series of videos, you can
overlay the start of each video with an animated title that identifies you or your company as
the creator of the series.
