View Full Version : video capture - frame rate not consistent

03-15-2007, 04:58 AM
Dear Colleagues,

I have been using Point Grey Dragonfly VGA IEEE 1394 (FireWire) camera to
capture video. The problem I have is that the frame rate is not consistent.
For example, if I set the frame rate at 7.5fps, the actual frame rate always
varies from 5fps to 10fps, sometimes even goes up to 80fps. I have tried to
use different resolutions and tried to disable unnecessary programs.
However, no matter what I did, the frame rate kept changing. Does anybody
have similar problem? Any solution can be suggested?

A summary of responses will be posted. Thanks in advance.
