using FireWire camera

Dec 18 2012 | 8:16 am

I’m trying to using FireWire camera. (device: Firefly MV)
I already checked the computer recognized the device and it works well.
But it doesn’t connected to Max.
I used jit.avc patch but it just give "jit.avc: could not find any avc devices"message.
Is there any solution?

I have used these cams as well. Only one way they work (on a Mac):

jit.qt.grab with dim 640×480

I’m using Window7.

Is it related with OS?

(still cannot find the device with jit.dx.grab)

hi taeyonii,
i been in same situation couple of months ago.
setting a FFMV in Win7 64 and i spend like three days to get it working in Max.. its a matter of the PGR drivers and not Max…

what works to me is:

1/ install 1.8 drivers 64bit version. use *custom installation* mode and check x64 and 32bit DLL and EXEs
2/ manually register the 32bit dll doing:


the knowdldge base of PGR is very good and
if you still having problems, speak with PGR support they are really helpful and can do remote sessions..

good luck!
