This timelapse is called GoPro HD Hero 2 Time-lapse 0.5 second sample movie, and was created by Gordon Laing on Vimeo. It is 00:00:18 long. The last time we checked (on March 31st, 2015), it had around 21,000 plays on Vimeo
Here’s a demo of the GoPro HD Hero 2’s new 0.5 second timelapse mode. This grabs a photo every half second (slower intervals are also available), which you can then assemble into a movie using third party software later. This was turned into a movie by Quicktime Pro, before scaling, editing and outputting into 1080p in Premiere Pro.
