What is Marker in virtual production?

A marker in virtual production refers to a physical reference used for tracking purposes. This includes both active and passive markers, which are most commonly seen on-set as props or special pieces of equipment placed within a scene. In simple terms, they act as signposts so that computers can better understand what’s happening in the environment they’re capturing.

These markers come in a variety of shapes, sizes, and materials but all serve the same purpose: to enable motion capture cameras to accurately track their movements in real-time, allowing digital effects to be created more quickly and efficiently. Examples include 3D printed objects such as cubes or cylinders, reflective spheres like those found in sports facilities, or even traditional wall art featuring QR codes or black and white checkered patterns.

At its core, a marker in virtual production is just a way of keeping track of an object's position at any given moment. It provides a visual reference point that makes it easier for computer vision systems to identify moving objects in a scene without relying solely on image recognition algorithms. The result? A smoother workflow and faster turnaround times when creating high-quality visuals.
