Well looked to me like it was on a sub orbital track to the NW assuming the camera was over LA. It was going away. I have seen a lot of launches from the cape. It sure looks like a solid fuel booster and appears to begin staging at the end of the clip. I have not seen a contrail going at that speed. Airliners only fly at 550knts.
With a corkscrew contrail near the ground.
