To improve your video
1) Motion Blur. video in direct sunlight so that your camera's automatic exposure control will select a faster shutter speed resulting in less motion blur.
2) Image Size. Get closer to the server so that he/she fills about 70% or more of the frame while always showing from below the feet to above the racket.
3) Camera Location. One location that is very informative is from behind the server, camera viewing along the flight path of the ball. Side view is also very good but motion blur is larger. For comments on video and some common serve problems
Search: camera behind Chas Tennis
To properly analyze the faster parts of the serve - the racket acceleration leading to impact and ball location on the racket strings - requires high speed video, where 240 fps works very well.
Are both your feet leaving the ground?
