Disclaimer: No airships were hurt in the making of this video.
In principal an airship is a stable pendulum, so any roll disturbance will likely be attenuated without further ado. However, when steady shots are required for detailed inspections of infrastructure then an active attenuation of any undesired roll oscillation can safe the day. Usually camera gimbals do a pretty good job at keeping the camera stable ... until the undesired movements of the aerial vehicle become bigger than what the gimbal can compensate for. This is why stabilizing a drone in all six degrees of freedom is a good point to start from. For multicopters that's standard but have you ever seen an airship do this?
