Raw 500 fps footage from Camera E-8 on the launch tower for the Apollo 11 Saturn V liftoff, transferred in HD from the 16mm original. More than eight minutes of film covers about 30 seconds of real time.
Why Hacker News points people here: HN commenters recommend it for its slow-motion view of the first seconds of liftoff and cite it when comparing launch pads and engine behavior.
“It explains the sequence of events over the course of 8+ minutes (30 seconds real time).”HN comment, 2019

500 fps Saturn V launch footage narrated through the full sequence of events.
Here is 500 fps film of the Saturn V launch for Apollo 11, narrated by Mark Gray. It explains the sequence of events over the course of 8+ minutes (30 seconds real time). this video
“Compare to this Saturn V launch.”
Saturn V launch showing pads handle rocket failure modes.
Unlikely, it wouldn't be much of a launch pad if it couldn't handle failure modes for rockets (aka bombs with a hole in one end). Compare to this Saturn V launch. this video
The F1 engine [1] (Saturn V, first stage) used another interesting way to improve efficiency with a gas generator cycle: using the turbopump exhaust gas as a cooling film in the engine nozzle. The fuel-rich exhaust was relatively cool compared to the flame generated by the rocket engine itself, and thus protected the nozzle from the most intense heat. This is why, close up, the flame looks almost black close to the nozzle [2]. [1] link [2] link Edit: Hopefully clarified a little, and changed the link in [2] (from this video ).
“they shielded the pad cameras during apollo”
Example of shielded pad cameras used during Apollo.
You could protect it in the same way they shielded the pad cameras during apollo (such as the E-8 camera this video ), with a quartz shield
