probably not, a webcam delivers live video, and as such has to be recognized to Windows or Linux, as a webcam, which the Nikon probably doesn't do.

But maybe it doesn't have to be a webcam to work in the Golf program.
Does it allow you to open up a video on disk? if so, what format?

if it does, and you can convert the output of the nikon, to the same format as the golf program , you're in business.
