I've got a show coming up where we want rotate the camera up to 90 degrees on the top stage of the Steadicam. I know this has been discussed but anyone know of an existing product I can add on and control myself? I would like to demo and possibly rent or buy. Alexa Mini to go inside.

How about the AR ? Alec Jarnagin used one to great effect on a commercial recently.

What Sanjay said. MK-Vs AR is getting a lot of attention right now.

Alec is definitely the go to guy for some info when it comes to operating the tool!

The AR I used for the OK Go video has been modified by its owner, Ramon Engle.  You do not use any of the level sensors, rotating monitor, etc. It is a simple carbon fiber roll cage that sits on any model Steadicam and plugs into your Preston MDR Zoom port for power.  It's rotation is then controlled remotely via a Microforce.

 

And Ryan, thanks for the kudos, but I am by no means an AR guru.  Outside of a demo or two, I have never used it as it was originaly intended.

That sounds like it would work. Is that something Ramon rents out or is it yours now?

What about that Letus Helix single axis that they were showing at NAB? Has anyone used that?

Lawrence, I'll send you Ramon's contact info via messenger.  Know that, you'll have to give the sled a bit of a death grip as the camera spins in the AR (obviously having the camera's cg centered within the cage as much as possible will help - but it will never be perfect).

I used it. Was useless. To much play. The lens bumped about 5mm up and down...(ScarletX was to heavy for it)

The AR needs a bit of modification, if you want to operate it without having to fight it. You need risers for the camera plate and utilize lens motors and other acc. to trim the camera on the Z-axis inside the cage. The whole sled should be neutrally balanced, drop-time, camera-cage and monitor/monitor arm.

 

If you want to rotate the camera, trimming the camera neutral inside the cage is mandatory. Furthermore it makes it a lot easier to have a monitor that rotates in sync. At least my brain is not capable to adjust the framing precisely with a fixed monitor while the camera rotates to 90 deg and 180 deg.

 

Lawrence if you go with an AR cage and a manual rotation have a second monitor like a starlite mounted 90 deg next to you regular one.

Thanks all for the input. This may turn into a 3 axis Lambda on a jib arm or a 3 axis remote head. They are trying to avoid the complication of building that in some very tight sets/locations.

Lawrence, the Chapman Miniscope sounds like it may work well for you.

I was trying to save a link off Chapmans Facebook page.

Its got a 7 ft telescope boom range and mounts straight onto a Hybrid dolly, and can take a 3 axis remote with full camera package.

Should work great for tight spaces.

I've seen it Sanjay. Nice piece of gear, especially for what they are charging for it. Looking for less complication. The key has an Aero jib and I've got remote heads. Original thought was a Movi but even that appeared overly complicated, time consuming, and fussy in the demo.

Hi Lawrence, Ive modified my AR cage with new electronics... which can now be used with wireless remote wheels to adjust roll over the top of horizon stabilization... email me if your interested...
