On larger birds with dual cameras, the FPV system is usually all-analog and typically operates on 5.8 GHz. In advanced systems, one operator flies the bird using the analog system for FPV while a second person operates the camera gimbal for the HD video system.
However, with a proper flight controller and a stable bird, the pilot could use the analog video to fly the bird into position, then hover while he switches to the gimbal controller to frame the HD video, and then switch *back* to the analog FPV system to fly the desired camera path.
