Where Will I Find a Video I took In Game?

I hit the wrong button and started a video while my game was playing. Rather than turn it off again, I decided to go with it. Erik was in the middle of a concert. I would like to share it (although I'll have to learn how this is done), but more to the point, where am I likely to find said video? Where in the game is it saved? Screenshots? Other?

Please, and thank you, in advance.
