iThis video by YouTube channel LowLightVideos shows the MoVI steadicam in action. It is an impressive piece of footage showing the filming process with the assistance of the steadicam as well as the impressively smooth footage. A steadicam is a great alternative to dollies and takes the jerkiness out of camera movement.
This is a very affordable steadicam and it bears good results. See video below by YouTube channel Andyax.
