 Because all of these links were analog, each one added additional noise and distortion to the signal.This low-quality optical conversion of the Apollo 11 moonwalk video images—made with a TV camera taking pictures of a video monitor—is what was widely recorded in real-time onto kinescope film and NTSC broadcast-quality two-inch quadruplex videotape.Recordings of this conversion were not lost and have long been available to the public (along with much higher-quality video from later Apollo missions).
