Yeah trying to capture video on to the computer really is a slow process,
I built a camera adapter for my old iphone and spotting scope I used to have. It worked very well. If you have a phone that records good video, and a decent spotting scope or whatever, adapters are pretty easy to make
I chose to Just buy a better video camera with a good OPTICAL zoom... digital zoom is JUNK. and I wanted a stand alone unit. One that did not take up my phone or my spotting scope.
