A scene is defined by a set of various sources. You can add, remove, or modify scenes by simply right clicking the scenes list box.
A "source" is typically individual images or video input which make up the currently selected scene. You can add, remove, or modify sources in a scene by simply right clicking the sources list box.

Global sources are sources that are independent of scenes, and persist until the stream ends. They start up when first used, and are destroyed when a stream ends. This is especially useful and recommended for say video devices such as web cameras or capture cards, or desktop capture. It is not really necessary for other things like regular bitmaps and such.
