  1. Regardless of who supplies the plate you must ask yourself do you want to be remembered as the operator whose footage had vibration? I always went out and got what I thought would make my work better. That being said, I never had an issue with Alexa vibration using stock PRO dovetails.

  2. Lawrence. they do sort of exist. Phil Cramer of Panavision toronto, built one for me but had to build a mini 3V circuit into the lemo. I know others who had burnouts but it always worked for me. there is the danger if the MDR is on unregulated power of zapping the Red, but i always run camera battery separate from the sled.

     

     

    I stand partially corrected. Preston does not make a cable.

  3. Josh,

     

    First off remove the strap from the camera and the lens cap. Believe it or not, that will effect the balance. Secondly, before you mount it to the Steadicam, attach the plate to the bottom of the camera (which you have already) sit the camera on a pencil or small tube and find the front to back balance point where it roughly balances on and then try and place that center point directly over the center of the Steadicam post. Same can be done with the side to side axis. If there is an adjustment screw on the top stage for side to side adjustment it looks like the camera needs to move to the right slightly. If not then use a different side to side hole on the dovetail plate to accomplish the same thing. If you run out of turns on the adjustment screws you will need to remount the camera in different holes on the dovetail plate. Also, as Janice has said, you may need to slide the gimbal up slightly to make it more bottom heavy. And all this would be easier to accomplish if you had a lighting or grip stand to mount this to.

  4. LVSC,

     

    If you live or work in Las Vegas, as your avatar suggests, then there are training sessions given there by Robert Starling. Additionally there are many things to learn about operating the Steadicam that are beyond just balancing it which you may benefit from by taking a course. Let's just say it's not as easy as it looks. Perhaps you are coming across a bit arrogant to those that have worked so hard to learn this skill or who have offered advice that is not exactly what you have asked for.

     

    Regardless, did you try what I suggested?

  5. Mount your camera on the top. Put the supplied weights on the bottom. Make the center post as short as possible. Now hold the handle with one hand and tilt the post until it is parallel to the ground (camera lens is pointing towards the floor). Now slide the gimbal (the ring that is around the center post and connected to the handle) either up or down the post until the camera does not want to tilt down to the floor or to the ceiling. If the camera wants to go towards the floor then slide the gimbal up toward the camera. And the opposite if the weights want to go towards the floor. If you can't slide the gimbal up far enough then extend the post which will move the weights away from the camera and make it more bottom heavy. And if it is way too bottom heavy and you have to slide the gimbal too far towards the weights then remove some weights. Once you have it close to even then slide the gimbal up towards the camera just a little bit so that it takes maybe 3 seconds for the weights to drop down to the floor and the post is pointing at the ceiling. Now once you get it close you want to have the post straight up and down and you will either have to move the camera left or right on the top stage via the small knob on the right to balance it side to side. If you can't turn it far enough to balance you may need to mount the camera in a different hole on the dovetail plate. Same thing with balancing front to back. If there is another knob there turn until the camera stays level or loosen the dovetail plate in the top stage and slide the camera dovetail forward or back as needed and tighten the dovetail in place. Yu may need to mount it in a different hole there too if that is an option. If it is too front heavy mount the camera further back and visa versa.

     

    If you can't figure this basic principle out take a class as others have suggested. If you do figure it out start charging $2000/day like everyone else. Good luck and USE YOUR REAL NAME!
