The non-moving objects are (left to right) XM-2 (Rock), XM-1 (Roll), XM-3 (Rhythm), and AMC-16. XM names their satellites, thus the "Rock", "Roll", and so on. All four are parked in geostationary orbits.

XM-1 and XM-2, both launched in 2001, are not being used, apparently due to a design flaw in their solar panels. XM-3 was launched in 2005 to replace XM-1. XM-1 and 2 are available as backups to XM-3 and XM-4, but at the moment they are (literally) just "taking up space". All the above XM's were launched by Sea Launch (no longer in operation) on top of Zenit-3SL rockets.

XM-1 and 2 are both Boeing 702 satellites with solar panels that span 48 meters (158 feet) which may help explain their brightness.

AMC-16 is a A2100AX satellite, built by Lockheed Martin. It was lofted by an Atlas-5 from Cape Canaveral in 2004 and provides television and other communications services.

WHERE ARE THEY NOW?

XM-1 was supposedly retired in 2016 and, depending on the source, has either been moved to a graveyard orbit around 39 West, or has been deorbited.

Cosmos 2397 (2003-015A) is a Prognoz 2nd generation Russian military surveillance satellite, intended to provide early warning of missile launches from the United States. It was launched on a Proton-K rocket from Baikonur in April 2003. The TBS-satellite.com web site listed it as being out-of-service due to a fuel tank problem only a month after launch.

In the original video (the above is shorted and played faster so as not to try the patience of the viewer) the flashes are consistently about 135 seconds apart through the entire 35 minute movie. In February of 2007 an observer (of whom I have no contact information) reported the flash period of 687 seconds. Could it have been hit by something causing it to increase its tumbling/rotation rate?

WHERE IS IT NOW?

As of early 2020 it is in a geostationary orbit over the Indian Ocean. Since it was reportedly out of service due to a fuel tank issue, I'm not sure how it got to where it is.
