You will have to synchronize the cameras together, and feed the common sync into the LVD. > Also, is it possible to transfer the contents of the digitizer directly > into a file WITHOUT transferring them to the display buffer. No. The LVD is attached directly to the graphics subsystem, not to the system bus of the machine. If you need to go to memory without going through the graphics, you might try a VideoFramer card instead. It is a VME-bus based board. ....paul -- Paul Spencer Silicon Graphics Advanced Graphics Division spencer@sgi.com Mountain View, California
