You can see the reflective thermal control material blowing off the descent stage at ignition. In one lunar ascent, the camera with the astronauts looking down saw a large sheet of it tumbling across the Moon for kilometers. With no air, there was nothing to stop it.
2/ If you freeze th video at the right moment, you'll see red, green, & blue pieces flying away in perfectly alignment. Really they're the same piece. The camera used a color wheel to get red, green, & blue images sequentially. It made each piece look different colors as it flew.
3/ The sequential red, green, & blue frames were merged into a single, full color video after the signal came down to Houston. Objects that weren't moving looked full color. Objects that moved fast had the red, green, and blue images of it spread out across the screen.
4/ The spacing between the three color images of an object tells us how fast they flew.
