Stabilization with hardware
Certain industries, such as the movie industry and the military, expect high quality video stabilization. Using just images in those varied environments would not work. This led industries to create hardware-based image stabilization rigs. For example, a quadcopter with a camera needs to have a high quality video output despite (potentially) bad lighting conditions, wind, and so on.

These devices use a gyroscope to physically move and rotate the camera so that the image sequence stays stable. The results look excellent since you're actually compensating for the motion of the camera.
These devices tend to be on the more expensive side and thus unaffordable for the common consumer. They also tend to be quite bulky. The average person would not want to carry a two kilogram rig on...
