Gathering B-roll for a video can make or break the production. We snagged this DJI Osmo to capture B-roll quick and easily. This small handheld device holds a 3-Axis Gimbal, along with a 4K resolution camera. The Osmo allows you to walk or run without having to worry about shaky footage. It's 4K camera can capture outstanding 12MP JPEG of RAW photos, and 4K or Full HD videos.
