How does Matrox MXO work?
When Matrox MXO is used with QuickTime-based applications that support the V-out component including Final Cut Pro, Color, Soundtrack Pro, Motion, and Adobe After Effects, it operates in “Mastering Mode”. Matrox MXO patent-pending technology uses the DVI port on your Mac computer in a unique way to provide frame-accurate audio/video output for insert editing and print-to-tape with guaranteed a/v sync. Normally when previewing video from a QuickTime application, the native YCbCr video (sometimes inaccurately called “YUV” video) is converted to the RGB color space for output over the DVI connection. The frame rate of the RGB video does not match the standard for broadcast video. For example, it may be 75 Hz rather than the 59.94 Hz standard for NTSC. The frame sequence, therefore, inevitably includes dropped and/or repeat frames. Matrox MXO, on the other hand, takes the YCbCr video from the QuickTime application and sends it directly out over the DVI connection with time-stamping informa
