- However: you still need to have a GTX/VGX/VGXT graphics system to
- be able to run VideoLab. The VideoLab board attaches to the graphics
- subsystem; it is NOT a VME-bus board.
-
- But yes, you can output frames to video without having to put them on
- the graphics screen first, just like the VideoFramer (except that
- VideoLab is faster).
-
- For FAST output, a Crimson/VGX/VideoLab can output LIVE video, but
- only if you do go through the graphics screen. Length of time is
- dependant only on how much main memory you have; NTSC video takes
- roughly 27 MB/second.
