Several time-lapse experts have asked: how can we use GBTimelapse AutoRamp with the Dynamic Perception MX2 dolly in two-axis mode - a combination of linear moco with pan/tilt? Previously, this wasn't possible because, the GBTimelapse/MX2 USB connection precluded the use of a pan/tilt head like the Merlin.
The Solution
Now there's a simple method: just connect your camera to the MX2 dolly engine using a special PC sync cable. With MX2 firmware version 0.92 installed (thanks to Jay Burlage), the dolly will move one step whenever the camera shutter closes.
About the cable you'll need
A PC cable connects the camera to the MX2 Dolly Ext 1
connector by means of hot shoe and PC sync cable. It’s not a standard PC cable
- it has a PC sync connector on one end and a TRS connector on the other. TRS
(tip, ring, sleeve) is also known as a “mini-stereo” or headphone connector.
This cable is available from Promote
Control for about $30. You don’t need their HDR controller. All you need is
this cable.
To configure the MX2
- Go to the Settings menu
- set “Motor S1.Mod” to “Interleave”
- set “I/O 2” to “Ext. Interval”
- set “Invert I/O” to “On”
- Optional: Under the Camera menu, set “Exp. Delay ms” to “1000”
- Set the main screen to “Ext” and set a step distance
Within GBTimelpase no configuration is needed. The dolly will move one step
after each exposure is completed.
Below is a very cool video by Mike Lanfor using GBTimelapse, a 5D Mk III, the MX2 and a Merlin pan/tilt head. As he says, he had to abort the test when the lightning got too close for comfort! Thank you, Mike!
