LEGO Motion Control v2

We’re building the next major iteration of the motion control system, and are thinking of supplementing the LEGO with some more stable parts – the major part is the baseplate of the rig, which we’ll use MDF to start with, and see how much stability it brings.

Tomorrow, the 1st iteration rig also starts getting use on La Goutte D’or, a stop motion puppet film in production in one of the other buildings here.  With the new seek algorithm, I’ve sped up the incremental moves by 300%, which means we can shoot about 8-12 seconds automated per hour.

The movies above represent moves run with the new software.  I’ve started consulting my handy American Cinematographers Manual to look at the pan and lift speeds.  Both moves are processed with the “smoothcam” node in Shake.  As far as I can tell, the amount of pixel shifting that happens when smoothing has a minimal effect on the plate – I don’t see much introduced blur, especially since our processing happens at 4K (roughly), and then gets downsized to 2K.  I haven’t yet tracked a “smoothed” shot, so I might discover some issues there.  The jitter in the original plate is also pretty minimal, and hopefully with the next iteration of the rig, we can bring it even further down.

Below are some images of the 1st iteration.

  • It’s fasinating system you built! I’ve been working with MOCO systems from General Lift for bigger set and shooting for years, the controlling software Kuper is allmighty but really hard to understand with a thousand hiden settings….and to setup and take apart the rig on set, that’s the least fasinating part ever!
    Will you share the building plans and software?

    Congradulations from China!
