4) Realize that if you video with a camera that has too slow a frame rate you can get a lot of very useful information on the slower parts of the serve as most comments indicate. However, with low frame rates (30 fps) you cannot see the faster parts of the serve leading to impact and might mislead yourself about what you are doing in your service motion.
