SnapRoll Media is a US-based company (from Tennessee) specialized in high definition aerial video-capture. They started with a drone and DSLR camera. But now they are using Red One camera and Phantom Flex/Phantom Gold HD Cameras with their “huge mini” helicopter.

“For the past few years, SnapRoll Media has been at the forefront of remotely controlled aerial camera systems. Like most, we started out using DSLR cameras to record video, but it wasn’t long before the image quality wasn’t up to our standards. We began designing and building larger airframes to carry the weight of the cameras we and our clients wanted to use.
Our hard work paid off. We were the first to successfully carry the RED ONE digital cinema camera safely and smoothly. Then, we added Vision Research’s Phantom Flex and Phantom Gold high speed cameras to our arsenal.”
