Visual effects (VFX)
Data capture technician
Also known as: Data capture, On-set, On-set coordinator
What does a data capture TD do?
Data capture technical directors (TDs) go onto the film or TV set to collect the information about the live-action footage that the teams in the VFX studio need to add the visual effects.
They take photographs of the set and the way the cameras are positioned. They “capture data” about the type of lens type being used, its focal length, filters, focus and colour temperature. They also record the camera height, camera mount and distance between the camera and actor, and other details. And they take photos of surfaces, so that the textures can be recreated digitally later on.
All this information is necessary so the exact scene in the live action can be recreated digitally and the VFX can be incorporated in a believable way.
Data capture TDs use a variety of tools to capture the data, including cameras and a ‘total station’ which electronically measures horizontal and vertical angles and distances.
They upload, log and backup all the data, before sending it on to the relevant members of the VFX company on a daily basis.
Data capture TDs tend to be employed by VFX companies or studios rather than work as freelancers.

What's a data capture TD good at?
- Being accurate: be methodical in your work, pay close attention to detail, have strong problem-solving skills
- Technical knowledge of cameras: have an in-depth understanding of all motion picture equipment, cameras, lenses, monitors and lights
- Understand the VFX pipeline: know the process through which visual effects are created

- Being efficient: work quickly and accurately on set so that the physical production can run smoothly, organise and prioritise your tasks
Who does a data capture TD work with?
Data capture TDs work with camera trainees and camera operators on set to gather data about the cameras, camera shots and lenses. They also work with script supervisors to the same end.
Data capture TDs work with the VFX supervisor and matchmove artists on set to ensure that the sets and actors have tracking markers placed on them in the necessary way so that the footage can be used by the matchmove artists and roto artists.
They also need to communicate with the various VFX artists and compositors who will be using the information that they have provided.
How do I become a data capture TD?
Employers tend to want you to have a couple or more years’ experience working either on sets or in VFX before taking you on as a data capture technician. As such, one career path is to work in the camera department in the film and TV drama industries. This will give you good knowledge of cameras so you can more accurately collect camera data as a capture technician. It also gives you on-set experience. Try to get onto ScreenSkills’ Trainee Finder scheme as a camera trainee.
Another route is to first work for a VFX company as a matchmove artist. That is an entry level role in the VFX industry. It gives on-set experience and also involves working with data capture TDs to place tracking markers on actors or parts of the set. Matchmove artists often have a degree in computer graphics, computer science or computer animation.
