I?m working on a video project and I try to capture from a FireWire Cam in PAL resolution with jit.qt.grab and jit.qt.record.

With this solution I always have performance problems on a G5 1,8 ghz. 

I can?t capture at the full framerate of 25fps.

Capturing video in iMovie or FinalCut works also on a slow G3 very fine.

Do you have some advice for me to do some "iMovie-like" capturing in max?

Try this. I believe that getvmode should see your camera as PAL. I 

also set the frame size to PAL manually so that it is full frame, not

half frame.

in addition I discovered that the jit.qt.grab object accepts also a write message and writes the video directly to disc.

so I eleminated my performance problems cause I don?t send the video through a jitter matrix anymore...

capture from FireWire DV like in iMovie or FinalCut
