Is there a way to minimise or eliminate lost frames when saving to disk?

I am using the code that I have taken from the CreateVideoFile sample and placed it in a larger program. I also have a device that flashes led's when a frame is recieved. This is synced to the camera.

Every now an again I see dropped frames.

I am saving in a different thread but do have a single processor machine.

Any advice would be great.

Hi Glenn,

I found an interesting web site about frame drop:

Thanks I will look into some of those and see if they help.

IC Capture seems to do ok.
I suspect it is todo with the environment I have to use (CVI / Labwindows).

Thanks

Glenn,

LabView is a little bit slower than C++, this may is a bottleneck.
