This video shows the power of the new GoPro Hero 3 Black with the 720p120 mode. We recorded the Atlas V launch at 120 frame rate then conformed the video to 720p30 instantly getting 1/4 speed with no loss of information. This was not quite slow enough for us so we cut the speed by 50% giving us 1/8th real time.
The quality of the video is stunning and you can clearly see the deluge of the water system, followed by the green coloured sparks of the ignition. With the rocket engine ignited the exhaust spews out of the flame trench, before the rocket is finally released and starts to climb into the sky.
