Working with Sources

A source object represents a single media stream from a source file. Sources provide the raw material for a project. Everything else in the timeline exists either to provide structure ( tracks , compositions , and groups ) or to modify sources (effects and transitions).

This article describes various details relating to sources in Microsoft® DirectShow® Editing Services (DES). For information on the basic steps needed to add a source to the timeline, see Constructing a Timeline.
