Festivr was sort of a experimental project to prove the possibilites of panoramic video in the marketing field. I filmed world famous music festival as a 360 degree videos, and I have had chances to collaborate with some major promoter companies that manage music festival events.
I filmed panoramic video with 3d printed camera rig which combines 6 GoPros, and edited clips by stitching programs.
This is a sample 360˚ video of Global Gathering Korea music festival.
