Firewire is better for video, because firewire is a more sophisticated interface. Firewire provides for device to device communication, DMA transfers and other performance features that USB does not.

You will need a time base corrector (TBC) or frame synchronizer to correct the problem. Ideally, you should also have a way to view and adjust the video levels. Usually ...

No matter when the camera shutter is active, if the frequencies of the video vertical timing (the frame rate) and the laser pulse are not congruent, you'll see partial exposures as they drift apart. The solution is to trigger the laser pulse on every other vertical sync time. The details on extracting the vertical interval will depend on the camera, and how ...
