I really dig when people do comparison shots between balls where they line up with the ball the video is for, strike, then throw shots at the same spot with other balls and show the results, then move with the other balls and show the adjustment needed to strike with them. Gives a nice comparison of what to expect difference wise with balls (yes I know some house patterns make it nearly impossible to make balls look different, it's why I don't even try and make videos)
Other than that, just some good camera angles and a narration of what you see in the ball, like Luke and Tamer do, instead of some obscure background music, and you're on your way to a great video.
