Free Multi-Screen Playback
MultiScreener is a set of freeware applications that synchronize the playback of Quicktime movies on multiple computers, using a local network to tie them all together. (It can also sync multiple movies on the same computer using multiple monitors.)
It is intended for multi-channel video art, video walls, trade shows, and digital signage. I designed it as an artist-friendly low-budget alternative to the expensive combo of industrial DVD players (Pioneer DVD-V7400, DVD-V5000) and Dave Jones Design sync boxes. Those systems are fantastic, but MultiScreener provides synchronized multi-screen video playback using commodity hardware.
There is a Server and a Client. The server plays a movie and also sends position information over the network. Each client "listens" to the server and subtly adapts its movie playback speed to stay in sync. There is no limit to the number of clients.
MultiScreener was based on the implication that each client would run on its own machine, but you can also run multiple clients on the same computer, with each client feeding a different monitor.
Looping and de-interlacing are available, and all settings are automatically saved for unattended startup. MultiScreener can output to the computer screen or external video devices (like DV cameras or decks). There is no native resolution or frame-rate, so all Quicktime video formats are supported.
