N2P, enter this idea with caution. Video is okay, as long as the cameras are not distracting you from what you're there to do - learn. Don't fly for the camera, fly and learn. I know that this is a Youtube world and everything, but be assured it is possible (and perhaps easier) to learn to fly well without video, many of us have done it! Indeed, when I learned to fly, Super 8 movie was all there was. My buddy and I (both licensed at the time) took one once - the result was uninteresting.
I suggest investing your money in more flying, rather than more equipment - instead of watching yourself do it, again, do it again! But I must also yield to the tech of today's world, so if you gotta, you gotta, just do not get distracted!
