The Macintosh Centris 660AV and Quadra 660AV come with 1MB of VRAM on the
logic board, which is not expandable. When bringing video into the Centris
660AV and Quadra 660AV, you must set your monitor to 256 Colors (8-Bit) when
using both Video Monitor and FusionRecorder. Even though your monitor is set
to 256 Colors (8-Bit), you will be capturing your image or movie in Thousands
of Colors (16-Bit).
