An encoder is an essential tool for virtual production, acting as a data capture device to collect performance capture data from physical inputs such as camera rigs, jibs, drones, and more. In other words, it's the lifeblood of any modern-day digital shoot. Encoders allow filmmakers to take real-world footage, layer it with computer graphics (CG) elements and other effects, then output the mix in various formats – all while maintaining ultimate control over their project’s look and feel.
The importance of encoders within virtual production can't be understated: they provide an effective way to take physical objects and movements and capture them digitally. This process helps create realistic environments and characters that can be used in film or video projects. Using encoders also allows filmmakers to experiment with different shots or angles without reshooting scenes multiple times. As such, encoders are becoming increasingly popular among directors and cinematographers who want to explore innovative techniques without breaking the bank.
In terms of those responsible for using encoders, the job typically falls on the director and/or DoP (Director of Photography). They must ensure that the hardware is correctly set up and configured so that the motion capture data is accurately recorded. Additionally, they must ensure that the captured footage is stored securely and ready for editing later. If a mistake is made during recording, it could mean hours spent re-recording footage – something no filmmaker wants to experience.
