E-Image GH25XR-PRO Virtual Production 100m Pro Fluid Video Head

The GH25XR-PRO is high-performance head & lens tracking system that serves as a crucial component of XR systems. This virtual system consists of an encoded head, XR data processing device, zoom/focus lens encoders, and DC power cable, and is specifically designed to collect precise data on the pan and tilt angles of the head, as well as the zoom and focus of the lens. Real-time virtual data is transmitted to the XR data processing device and can output tracking data via the FREE-D Protocol using either an RS422 or RJ45 interface.

Encoded Tripod Head
The GH25XR Fluid Head features integrated encoders that accurately track and relay the pan and tilt positions in real-time. Data from the encoders is output through an 8-pin locking cable. The tripod head supports cameras up to 55 pounds and offers adjustable counterbalance, pan, and tilt drag settings.

Data Box
The XR Data Processing Device captures data from the lens focus/zoom encoders and tripod pan/tilt encoders and outputs the encoded data to the Free-D protocol via RJ45 UDP or RS-422 serial data. Free-D is a widely adopted protocol used in virtual production to convey real-world camera movement and positioning data to digital environments. Once the Free-D data is output to the Free-D protocol, it can be received by any Virtual Production software such as Brainstorm, Vizrt, Avid (Orad), Unreal Engine, Ross Video, Qimera, and more. The indicator lights display status for data reception, genlock connection, and Free-D protocol output.

Lens Encoders
The encoders connect to the focus and zoom rings of a broadcast lens, capturing the data and encoding it to the Free-D protocol. The included lens encoders are compatible with the vast majority of broadcast lenses and include 0.6, 0.5, and 0.8 pitch gears that mount directly to the lens or to a 15mm rod. With a high resolution of 65,536 count/revolution, the magnetic sensors are able to pick up the most subtle lens adjustments.
