6 Click the Color pop-up menu to display a list of eight possible colors, then choose the
color you want for the marker.
7 Click the Type pop-up menu to choose a marker type:
 Standard: The default marker for use in Motion
 DVD Menu Loop: When you are using a Motion project as a menu background in
DVD Studio Pro, the DVD menu normally plays through the entire Motion project,
then starts over at the beginning of the project. When a loop point marker is defined,
the DVD menu plays the Motion project to the end the first time through, then starts
over at the loop point marker for subsequent loops.
 DVD Alpha Transition: When you are using a Motion project as an alpha transition in
DVD Studio Pro, this marker sets the point where the alpha value of the transition
(the Motion project) becomes 0. When a Motion project is used as a transition, only
its alpha channel is used when blending two pieces of video in DVD Studio Pro.
