IS it possible to use 2 simoultaneous firwire cameras with jitter, and visualise them simultaniously?

If so is there any particular order by witsh jitter processes the information from both cameras ( even if a milisecond diference) or would both be processed simultaneously?

I've found it possible to do so by just adding the arguements @vdevice(number of device) to the grab objects you use (you have to fiddle with the numbers to find the right one. I'm not sure about the syncronization issue.

Bigger the resolution bigger is sync problem.

Pc have no problem recognizeing multi cams if you have multi firewire cards installed .

With MACPRO i had more problems because apple dvcodec does not support multi cams.(BUT you can try) On the same machine with bootcamp XP runs superb.

Use multiply jit.dx/qt.grabe with @vdevice argument.

I use 4 dv cams with my project.

I didn't realize about the 2 firewire thing on apples. I've only ever run one firewire cam and the built in iSight at the same time (which is on the USB bus).
