This video shows a very fast moving object rising from right to left out of the right corner of the frame. At 40 seconds, the poster provides a slow motion repeat of the image that shows the object clearly. It is not a bird or plane, and does not appear to be a photoshopped. Probable unknown from South Texas, which is in the midst of a UFO flap.
