Wirecast is an application that makes it easy to create dynamic webcasts. It has been designed for building detailed multimedia broadcasts with many cameras, images, titles and movies etc. Traditionally such solutions have required expensive dedicated hardware and been out of reach to most users. Wirecast introduces the unique concept of shots. You can package up your selected cameras, graphical overlays, movies and titles into a shot. Once you have built your list of shots, you can transition the broadcast between them with a single mouse click.
Controlling your broadcast in real-time is easy. With Wirecast's multiple layer support, it's simple to place a background music track or a company logo over your webcast, while changing between the cameras you want your viewers to see.
Wirecast takes advantage of the QuickTime Streaming architecture (and Windows Media on the Windows platform) for broadcasting. Using QuickTime, you can unicast or multicast to your clients. When you want to scale your webcast up, you simply send your broadcast to a Darwin or QuickTime Streaming Server. Your viewers can then watch your webcast through QuickTime Player or embedded directly into a webpage.
Windows Media supports both a push and pull model, viewers can either connect directly to your machine using the "pull" method or when you need to scale up you can "push" your broadcast to a Windows Media Server. Viewers will connect either through Windows Media Player or directly inside a webpage.
