Technical Support & Installation Engineering Guide

The Hima xR Series is purpose-built for the demanding environments of In-Camera VFX (ICVFX) and Virtual Production. Achieving a seamless “Digital Twin” environment requires more than just high-resolution panels; it demands precise synchronization between the LED volume, the camera tracking system, and the render engine.

1. Studio Geometry & Spatial Calibration

Building an xR Volume (Stage) requires absolute structural precision to prevent tracking drift and visual artifacts.

• Seamless Curved Volumes: Hima xR supports high-precision mechanical curving. We recommend a minimum radius of 5 meters for LED volumes to ensure the camera’s focal plane remains consistent as it pans across the background.

• Zero-Gap Floor Integration: When combining Hima xR walls with LED floors, we provide specialized base-frames that ensure a <0.1mm transition gap, preventing visual “seams” at the contact point between wall and floor.

• Tracking Marker Integration: The Hima xR frame is designed to be compatible with infrared (IR) tracking markers (e.g., OptiTrack or Mo-Sys) without obstructing the LED pixels or causing heat interference.

2. Optical Performance & Camera Sync

To eliminate the “Moire Effect” and flickering, the Hima xR series utilizes high-end driver ICs optimized for film.

• Ultra-High Scan Rate: Hima xR features a 1/8 or 1/16 scan rate (depending on pitch), which is critical for high-speed cinematography. This allows for shutter speeds up to 1/8000s without horizontal scan lines.

• Genlock & Frame Multiplication: Our systems support Phase Offset and Genlock synchronization with professional cameras (ARRI, Sony, RED). Hima xR supports frame rates up to 240Hz, enabling multi-camera shoots where each camera “sees” a different background on the same screen.

• Color Gamut Accuracy: Calibrated to 99% DCI-P3, Hima xR ensures that the “Digital Green” or virtual backgrounds match the physical props on stage, reducing post-production color grading time.

3. Low-Brightness Grayscale & Ghosting Mitigation

Virtual production often requires shooting in low-light “moody” scenes.

• 16-bit to 22-bit Grayscale: Standard screens lose detail in shadows. Hima xR maintains a true 16-bit grayscale even at 10% brightness, ensuring that dark gradients remain smooth without “banding” effects.

• Ghosting Cancellation: Our specialized circuit design eliminates “upward ghosting” and “downward ghosting” common in high-contrast xR content (e.g., a bright moon against a black sky).

4. Acoustic & Thermal Management

Film sets are highly sensitive to noise and heat.

• Silent Operation (Fanless): The Hima xR utilizes a high-efficiency power-slab design that requires zero cooling fans. This ensures the studio remains at <20dB, allowing for clean audio recording on set.

• Low Heat Emission: By using common-cathode technology, Hima xR runs 15°C cooler than standard panels. This prevents the “oven effect” for actors standing close to the LED wall and reduces the load on the studio’s HVAC system.

5. Data Pipeline & Unreal Engine Integration

• Fiber Optic Backbone: For large volumes, we recommend a 10G/40G fiber optic infrastructure to handle the massive data throughput from Unreal Engine to the LED controllers (e.g., Brompton Tessera or Novastar MX Series).

• Latency Minimization: Hima xR, paired with professional controllers, achieves a sub-2 frame latency (from render node to LED pixel), which is vital for real-time talent interaction and movement.
