I know it's exciting and everything, but please consider the importance of just keeping your mind on flying. Not checking to make sure the video is recording properly, and then fixating on how your flying will look on video later. If someone would like to video you from the ground, so be it, that's where the camera belongs. When you are a very experienced pilot, you can explore video while airborne.
A lot of really bad things have happened with pilots saying or even just thinking "watch this!" just before it happened. Your skills will not be developed to the point where you can manage the slightest distraction, come first solo time, so keep them to the utter minimum.
Tell us when you do your first solo, and we'll all believe you, and congratulate you. We've been there, and we remember the feeling. We don't need the video proof. Many of first soloed back when the plane we were flying would not even carry a video camera of the day, so don't worry, we don't expect video from you!
