A Guide to Motion Control Filmmaking

Motion control involves a robotic rig that moves the camera with exceptional precision and repeatability, enhancing the quality and creative potential of tabletop productions and other filmmaking applications. Filmmakers are increasingly recognising the exceptional visual potential of motion control, driving its popularity. 

It's particularly valuable for capturing previously impossible action scenes. Motion control is also gaining traction in tabletop productions. Equipment availability and projects using motion control inspire bolder and more imaginative uses. Smaller systems like Bolt enable work in diverse locations, while high-speed cine bots used as Glambots add splendour to event coverage. 

In virtual production, where high-speed cameras and fast moves are used, camera tracking by motion control software is more effective than the optical tracking used in such projects. Ultimately, it's the creative directors and operators who embrace motion control that shapes film technology. At TILT, we've got a garage full of those fearless trendsetters!

In this guide, discover everything you need to know about the benefits and applications of motion control in tabletop and live action production.

In tabletop productions, cinebots like Bolt offer incredible speed and precision, creating visually stunning shots that capture the action in fractions of a second. In live-action, motion control allows multi-pass repetitions for scenes requiring complex post production or character multiplications. Dynamic robotic movements are often used to enhance the excitement of action scenes.

Motion control systems offer a range of benefits compared to traditional camera dollies or cranes. These advantages include smooth, precise and repeatable movements, allowing for accurate framing and continuity. Motion control enables complex and dynamic shots with custom trajectories, expanding creative possibilities. The triggering and synchronisation of camera movements with other elements like lighting and practical FX enhances visual effect. Automation and programming eliminate human error and increase efficiency. Motion control seamlessly integrates live-action footage with visual effects. Additionally, it excels in capturing high-speed, time-lapse and stop-motion sequences.

We can track falling objects, follow the liquid flow, and create the impression of stopping objects in flight. Stunning effects are achieved by using two robots on one set, where one moves the camera and the other as a model-mover synchronously, quickly, and with inhuman precision moves the object in front of the camera. 

It relies on specialised software operators used to program the rig's movements. This process requires high specialisation and familiarity with the specific system. At TILT, we have the pleasure of working with specialists who are considered among the best and fastest in Europe. The operator programs the robot's movements and synchronises any triggered effects. Rehearsals are often conducted a day before the actual shoot, focusing solely on executing the shots on the shooting day. During rehearsals, the team ensures perfect framing and precision in triggering effects. 

In tabletop motion control setups, the Bolt Robot Arm is the go-to equipment. It's renowned as the fastest motion control rig available, allowing for incredibly swift and precise high-speed movements. For live-action filming, the Bolt on Track system is widely utilised. This rig combines precision with incredible speed on tracks. It's worth noting that Bolt is not used alone; it also triggers numerous mechanical special effects, making it a versatile tool. By combining Bolt with high-speed recording using a Phantom camera, filmmakers can capture magnificent footage even over 1000 frames per second, with a moving camera. The applications are limited only by the creativity of the filmmakers.

Each project presents unique challenges that we find both interesting and enjoyable to tackle. One significant challenge is location. For instance, for one of our McDonald's projects, we filmed complex scenes with Bolt JR inside a bus and a tram while travelling around the city. As long as the doors are wider than the robot, almost any place becomes feasible for motion control. At TILT, we often travel with our robots which allows us to work in various places throughout Poland and Europe. We have already completed projects in Croatia and Austria, expanding our reach and versatility. Safety is always a priority, especially when working with high-speed robots. We maintain focus and adhere to established workflows to ensure a smooth and safe production process.
