Hundreds of reflecting markers on an actor's outfit are tracked by high-resolution cameras in modern systems, which record movements with astonishing accuracy. Actors can now roam about more freely thanks to some technologies that have even progressed to marker-less capture. Thanks to better algorithms that can convert muscular motions into intricate animations, facial capture has also advanced significantly.

Additionally revolutionary has been real-time rendering, especially in virtual production. Directors can see how a scene will appear while it is being filmed by employing game-engine technology, such as Unreal Engine, which enables creators to visualize motion-captured performances in real-time. Actors and their virtual environments can interact more naturally thanks to this immediacy, which also helps to streamline procedures.
