When we featured Imagination we were intrigued by the bullet time sequences that the short movie featured. I asked Marc Donahue from PermaGrin how those shots were accomplished and luckily for us, Marc shared this info.
The magic behind those timeslice sequences was a combination of using 20 Gopros mounted on a curved rail, some special triggering cable from Cam-do and levitation post production techniques
Here is how Marc describes it:
As I mapped out the shots for “Imagination,” I knew that I wanted to implement our GoPro Array Curved Rail mk II system in some way. I thought the best way to show off what it could do would be with balloons. Using the 20 GoPro Hero 3 Black Editions, our 6 foot version of the Curved Rail mk II, and a sync cable provided by our partners at Cam-Do, we shot the star of our production, Kai Burich, standing on top of a chair holding the balloons. Once we were happy with shots we got, we removed Kai and the chair to shoot a clean slate where we could then paint out the chair in post.
testing
The actual shots were taken with the star standing on a chair that was later removed in post
This is not the first time Marc (or Permagrin) use this technique to create awesome work.
