Video Output Screen
ProVideoPlayer uses your computer's VGA or VGA monitor port, taking advantage of MacOS X's extended desktop capability. That means when you plug in another display device like a monitor or projector, your desktop expands to take advantage of this new display. What you will see is your main screen with the ProVideoPlayer interface, and a second screen through your other device. You will be required to set up your output screen both in System Preferences, and in the ProVideoPlayer Screen Preferences.
Using a Projector or other Display Device | |

Connect a projector to the Monitor port on your computer. ProVideoPlayer will automatically detect the external screen on start up. Choose Window > Show Video Window (Command-1) from the file menu to show or hide the video out. If the video appears over top of the ProVideoPlayer interface on the main screen, you will need to quit and restart ProVideoPlayer for the auto detection to occur. Use Video Preferences to adjust output settings. (see Screen Settings above) |

To make the remainder of the set up easier, click on the "Gather Windows" button to bring your secondary display preference window to the main screen. It will appear behind your current setting window. Click the title bar of this window to make it active. Select the output resolution you desire from the available display settings options, but be mindful that lower resolutions result in optimal video playback performance. |
Window Settings | |

Choose Window > Show Video Window (Command-1) to toggle the Video Out screen on and off. The video out screen is typically your secondary display, be it a monitor or projector. If you start ProVideoPlayer up without a secondary display connected, your main screen will be selected as the video out display. Use the Video Screen Preferences dialog to configure your required settings (see below). Toggling Manual/Auto Mode will determine how transitions are handled. See Manual Blend Mode for more details. |

Choose Window > Video Screen Preferences (Command-/) to open the Screen Preference panel. Enter the desired pixel dimensions for your output screen. Most Standard Definition signals will be 720 x 480. Typically, you will want to match your output device resolution in the Operating System Preferences to that of ProVideoPlayer Screen Preferences. "Tile Media Clips", under advanced features, will create a repeated pattern of the media set to a specified number of columns and rows. "Grid Mapping" allows you to setup a grid coordinate system by entering the number of rows and columns. See networking for more details. |
Audio | |
![]() |
ProVideoPlayer has basic audio settings. You can disable/enable audio to be included with our video out. And there is a master volume control. When a media clip is playing with audio, the sound level will fade in and out according to the duration time of the transition settings. |

This opens the display preferences for your main display, with another display preference window on your secondary display. You should see tabs across the top of the window that say "Display/Arrangement/Color". select "Arrangement" and make sure the checkbox on the lower left for "Mirror Displays" is NOT checked. Now return to the "Display" tab.
