This is an error from the operating system describing a problem with the IEEE-1394 bus. Normally it means that there is not enough bandwidth available on the IEEE-1394 bus to support the video format and frame rate requested. There are several possible workarounds:

1. Reboot the computer. This is often a transient problem that can be solved by a reboot.

2. Make sure that no other devices are using the IEEE-1394 bus.

3. Reduce the video resolution by specifying a different video format or reduce the requested frame rate.

To learn more about the VideoFormat property type

web([docroot,'/toolbox/imaq/videoformat.html'])

at the MATLAB command prompt.

To learn more about the FramesPerTrigger property, execute:

web([docroot,'/toolbox/imaq/framespertrigger.html'])

at the MATLAB command prompt.
