My serve has changed since I uploaded this video...I am surprised how much some of the tips here by members helped me to improve. The toss-up is so so important imo...

What determines the speed of the serve is the final racket head acceleration to impact. This occurs over the last 25 or 30 milliseconds before impact in a high level serve. Your video camera, if 30 fps, takes one frame every 33 milliseconds. It is not capable of showing the motion of the most important part of your serve.
Besides the low frame rate, the motion blur in your video is so large that the racket cannot be seen at impact. The side view is also important and the racket will have even more motion blur from the side. Direct sunlight would improve the motion blur to some degree. Your camera is useless, and maybe misleading, for the fastest, most important part of the serve.
I posted a very low cost camera with 240 fps and a fast shutter speed for videoing the serve. It can show the fastest details of the serve leading to impact.
