From Totally Hip Software:
LiveStage Professional is a QuickTime authoring tool for developers and digital media producers. This program provides a comprehensive environment for creating interactive QuickTime movies and video for the Internet, CD-ROM, DVD, or any other QuickTime-compatible environment. It's a great way to deploy videos in an interactive environment. You can integrate and manipulate more than 200 media types in their native formats, including MPEG-4, Flash 5, and Adobe LiveMotion--even in QuickTime VR projects.
One of the most important changes to LiveStage Professional 4 is the intuitive nature of the all-new user interface. First off, the Timeline and Stage now share the same window and provide both a visual and a linear perspective simultaneously. While you're there, you'll notice you can do much more by dragging objects onto the stage and altering them in place.
More right-click menus, more pop-up windows and more short-cuts equals less digging for track properties, less menu drilling, less redundancy in tasks. You'll spend less time and energy navigating around in LiveStage Professional 4 and get on with improving the quality of your project waveform. Version 6/6/2006 includes unspecified updates.
