Excellent orb video from San Antonio, Texas

The first part of this video is pretty interesting. It is one of the longest and clearest orb videos I am aware of. Mr. Strieber sent it to our video experts, and the response so far is that it is probably not a CGI job, and is not any obvious known object like a balloon or some sort of cinder. It moves with apparent purpose, almost as if it is displaying itself. The second part of the tape is of nighttime lights. Unfortunately, like most such videos there is no real way to determine what it is.
