The average guest test setup of Magic Mirror required the crew to transport a mini-tower computer, tv or monitor, video mixer, video camera, tripod, and cables. This equipment required 3-4 people to transport. By running Magic Mirror on a laptop, the two most cumbersome components of the system could be replaced with a much smaller, lighter device. Such a setup could allow a crew of 1-3 to easily transport the system. Laptop Capabilities IEEE-1394/USB Direct3D Video Card Support Win2K/WinXP Laptop Performance Magic Mirror requires a processor comparable to a 1.4 GHz Pentium 4. Implementation Execution of Magic Mirror on a laptop required replacing the dedicated PXC capture card with more generic capture device ports. Using DirectShow, support was added for any supported Windows capture device, including plug-and-play IEEE-1394 and USB cameras. Video Capture Filter: Reads video stream from system capture device. DV Decoder Filter: Converts the video stream from DV to various formats.
