DI4D launches HMC, 4D facial capture system

After several years of development, DI4D has launched HMC, a 4D-optimized facial capture system compatible with third-party software.

The DI4D HMC is equipped with a pair of high quality 4 MP stereo cameras and a precise focus adjustment mechanism. In addition, it integrates an LED lighting panel that provides uniform illumination of the actor’s face. The synchronization of the illumination system with the capture system reduces the brightness to which the subject is exposed.

At the same time, the DI4D HMC allows an aperture of F/2.5 to provide better depth of focus; short exposure to minimize motion blur; and low gain to reduce image noise. In addition, its continuous wireless sync function makes it possible for multiple HMCs to remain synchronized to the master timecode at up to 60 fps.

Versatility and light weight

The flexible open helmet-based design of the DI4D HMC provides a “comfy” fit for actors, while the carbon fiber arm offers rigidity and camera stability. Meanwhile, its quick-release cable tensioning system allows the headsets to be removed and put on quickly and repeatedly. The rechargeable battery provides up to 3 hours of continuous wireless operation and is interchangeable, ensuring minimal interruptions during shooting.

Of course, the DI4Dlive software makes it easy to remotely control multiple DI4D HMCs in the production environment. It offers a number of functions to speed up the process of setting up HMCs for multiple performers and multiple sessions. In addition, it simplifies the process of monitoring, recording, reviewing and managing multiple takes across multiple DI4D HMCs. DI4D also highlights that DI4Dlive offers features to facilitate 4D performance capture, such as camera calibration and 3D reconstruction using stereo photogrammetry.

Colin Urquhart, CEO of DI4D, states about the launch: “Our DI4D HMC is intended to fulfil the need for a high-end HMC solution optimized for 4D facial capture. The lightweight, ergonomic design allows the actors to forget about the technology and to focus on achieving the best possible acting performances. The DI4D HMC is compatible with most third-party facial animation solutions, but when it is used together with our 4D post-processing services, it delivers the most faithful and realistic facial animation possible.”
