Use the eFade plug-in to control the opacity of  a video track.
Adding eFade to your Live Set
To add the eFade plug-in to your Live set just drag the plug-in from the EboSuite Plug-ins folder to a group or an audio or MIDI track with EboSuite plug-ins. Note that the eFeedback plug-in doesn’t work on the master track.
Creative Fading
Use the Hue, Saturation, Value, Curve X and Curve Y dials to control the way the eFade plug-in changes the opacity. To create a regular fade, set the Fade dial to maximum and use the Dry/Wet dial to fade the video track in and out.
Smooth
Use the Smooth controller to even out the motion of the fade parameters. Increasing this parameter will make the eFade plug-ins ignore rapid value changes to reduce noise and to create a more continuous, fluent, natural motion.
