"Following Nature's Documents Stan Szpak LENR Co-deposition"
starting at ~17:50 min shows the video in question. The point of the ir video is to show thermal variations acress the face of the codeposited cathode. If one reads the experimental descriptions from the SPAWAR group one concludes the field of view is ~1x 1.25 inches. (There was an actual slide in a presentation posted to the Internet once that showed this, but I failed to grab a copy and it shortly disappeared.) That allows us to calculate that an individual spot from a still is ~1-2mm in size, which is right in line with bubble sizes for this system. During the whole video one observes an intital period with no spots, a growing in of spots to the point where an area ~1/3-1/4 of the surface area is covered, followed by a dying away of the signals. Given that and the physical dimensionalites and the functional intent of the of the videography equipment, plus the later confirmation with a piezosensor, plus the fact that this is what would expect from ATER, I would not consider these 'spots' to be noise.
