  • Mirage VFX understands motion Control. We designed it and we built it with the strict guidance of David Pride whose history goes back 40 years as a VFX engineer and the first person to build motion control rigs in Australia. The Mirage rig needed to meet requirements in accuracy, speed, portability, weight and design. David’s reputation and exacting standards were flawless and we are grateful to have worked with a master of his craft – a true genius.

    As Mirage is a full CGI and post facility, we also needed to integrate or rig seamlessly to our 3D pipeline. Mirage is able to previs shots in a 3D environment to realise and foresee any issues and limitations with the rig, sets and lighting. It is the most efficient tool before shooting commences.

    At the heart of our motion control system is Kuper. Kuper is an Oscar winning Control card and software with hundreds of film credits and we are proud to have integrated it’s powerful robotic film technology. Currently boasting 10 live axis and certainly scalable to more axis, the rig has enormous functionality and maneuverability with very high reach and low reach capabilities ( please contact us for technical motion specs ). The rig has been designed to shoot on RED One, Epic, Scarlette and any DSLR ( currently in use is a Canon 5D MK II ). Each axis is controlled by precision micro stepper motors and geared by German built Harmonic drives – precision that can only be measured with micrometers!

    The Mirage rig has zero backlash, which means we can shoot multiple passes for lighting in perfect timecode sync or flash frame. This is also important for stereoscopic plate photography and sequences where compositing plates need to ‘fit’ perfectly.

    Finally, we are able to shoot stereoscopic plates in timelapse mode running Dragon Software. Choosing Dragon was easy due to its natural controls for stop motion photography and ability to work directly with Kuper. Also, when working with miniatures and stereoscopic plates, we use Dragon’s stereoscopic plate designed to allow scalable interocular distances depending on the perceived scale required. Anything from ’6.16 to 0′ inches of convergence.
