>>212052779 (OP)That wasn't 1969, it was 1972 for Apollo 17. Here's what Google's AI tells me.

Here's how it worked:
Remote Control: A camera operator on Earth, named Ed Fendell, controlled the LRV's camera remotely from mission control in Houston.
Anticipation and Calculation: Fendell had to anticipate the timing of the lunar module's lift-off and its rate of ascent. He used these calculations to determine where to park the LRV camera and when to begin tilting it upwards.
Manual Tracking: Because of the communication delay to the Moon, Fendell had to initiate the camera's upward movement several seconds before the lunar module actually lifted off to ensure the camera tracked it properly.
Previous attempts:
Attempts to film the ascent during Apollo 15 and 16 were unsuccessful due to technical issues (Apollo 15 camera motor burnout) and improper positioning (Apollo 16 LRV not parked correctly).
Regarding Apollo 11:
The famous footage of Neil Armstrong's first steps was captured by a camera mounted on the Lunar Module's descent stage and pointed towards the ladder.
The camera's signal was transmitted to Earth and converted into a broadcast format.
Note: The Apollo 17 ascent was successfully filmed by remote control, and the iconic footage is often seen today.
