Time lapse video of the Apollo 11 launch

I saw this link posted on a photography forum last week.

http://vimeo.com/4366695

They used a video camera that recorded 500 frames a second, so 30 seconds of launch becomes 8 minutes of movie footage. There is a narrator explaining what is happening during the launch.

Hi Henry,

To add some info to your post. All the launches were filmed actually using 35mm film not video maybe even 65mm film, and because the cameras used were run at 500fps as you say the cameras were arranged in a turret of four each where a left hand and right hand camera side by side mounted upside down with another two mounted on top. Each camera had 1000 ft of film and each was synced to ramp up as the previous ran out. At 500fps the 16000 frames of a load would only last 30 secs., so usually several turrets of four cameras were used to record the entire launch.

Cheers Rob

7,648,000 pounds of thrust through five engines, guiding a 6,699,000 pound (launch weight) rocket up a 2 inch corridor, and burning fuel at a rate of 15 metric Tonnes every second.

That's the same fuel consumption as 33,000 747s (Jumbo Jets) at take-off!!!


***A 747 burns between 9.6 to 11.6 pounds per second at take-off (assuming a specific gravity of 0.88)***

Hi Robert and others,

I should have said it earlier but everything bar the first sentence (including the topic) in my first post was a copy & paste from the following thread on the Camera Labs forum:

http://www.cameralabs.com/forum/viewtopic.php?t=21873

I did not post in that thread but I am a member of the forum. My username on Camera Labs is onlinedrifter.

Ron, what I did was hit the pause button when it first started and looked at other threads while it was downloading to my cache.

I need to do that with most videos.

Ron, sorry about the delay in replying. FireFox crashed and then my email program crashed. I did not expect to be still logged on after a computer reboot.

Back on topic.

The trick described above was learned back when I was on dial-up and watching YouTube videos. Anything that played for more than 3 minutes took too long to download.

Thanks Henry for sharing, great footage and narrative.

The Saturn V would arguably have to rank as one of the most sophisticated pieces of machinery ever built. Just awesome power

Cheers Norm
