With gravity gimbals like Steadicam, does the weight of the camera and the weight of the counterweights together have an overall impact to the stabilising effect? That is, suppose the same drop time in two setups where one has a 200g camera whilst the other has a 1kg camera. Will the stability be better in one?

Actually, what is the term for non-motorised stabilisers? It seems "gimbals" seem to refer to motorised stabilisers these days.

Any thought appreciated.

Gimbals are nothing more than a ball bearing (or a complex series of ball bearings; or even simply a sharp point which rests on a surface which allows it to move on a 2 axis level), which using weights balanced correctly provide a "zero gravity" effect on both the camera and the counterweight.

This doesn't apply to electronic gimbals which use servos, a microprocessor, and sensors to electronically move the gimbal head.

That said:

Yes weight will play a role in the overall stability of the camera unit.

I have taught workshops on camera technique, and I often joke that if you want to get steadier footage from a small lightweight camera (think GoPro), gafftape it to a brick.

Mass requires energy to move. So the lighter the object, the easier it is to move. Try to shake a marble around with your hand grasping it with two fingers, then do the same with a bowling ball. The motion, if you tracked it, would be both smoother, and more stable - smoother arcs, turns, etc, with the object that has more mass.

So with a steadicam rig (which I used to own a full blown rig capable of holding cameras in the 30lb range); a heavy camera with a heavy counterweight, which is properly balanced with give you far steadier shots, SPECIFICALLY with vibration. As a large heavy object is hard to "vibrate". So the little shakes, will be minimized by the mass added to the camera.

What's most important, if using a steadicam type rig is that you have perfect balance, that is, if you turn the camera 90 degrees (thus shooting sideways) the camera will stay in that position.

You do not want to set it up so the unit is counterweight heavy, keeping the camera upright.

The camera should be able to "hold" any position, angle, on any axis, and not return to upright.

If the camera is not balanced this way, you will encounter what is known as steadicam wobble. This is where the balance is off, and by the operators movement the effects of inertia and momentum push and tug differently on the camera vs the counterweight.

Lastly, the term for non-motorized stabilizers is a camera stabilizer. There is no one term; but steadicam is a goto term used by most.

Now as far as motorized stabilizers, none of what I said factors in, because the motorized stabilizers I own and have worked with, do not use weights, rather they use servos, and tension systems which differ than their non-electronic counterparts.

If you are using a light weight camera, and non-electronic steady system; you will achieve better results by adding ballast to both the camera and the counterweight. The ballast you add can be steel plates with holes drilled, cheeseplates, anything that has weight, and that you get the unit balanced to where it is not bottom heavy.

  • To follow up, by far the best way to balance your rig is to set it up on a light stand, and if necessary a boom so there is room to swing it around. No matter what position the camera is in 40 degrees left, 15 pitch down, yaw 10 degrees left, when you let go- it should stay right there. If it begins to pitch back, or down, or in any direction- the balance is off. Getting it spot on takes time, and adding so much as a small cable can throw it off. You will know its off if when you begin to walk from a standstill, the camera pitches forward or back. It shouldnt. It should stay level. Commented May 15, 2016 at 15:35
