GhostFrame: Revolutionizing On-Set Production and ICVFX Efficiency 

Summary: GhostFrame is a patented technology that leverages high-speed LED refresh rates and nanosecond alignment with camera shutters to capture multiple hidden layers in one take. It enables simultaneous chroma keying, invisible tracking markers, and up to four unique video feeds without adding hardware latency. ROE Visual is the exclusive LED partner, providing the high-performance panels required for these complex, multi-frame broadcast and film environments.

Quick Answer: GhostFrame uses nanosecond LED sub-frame alignment to capture hidden tracking, chroma keys, and multiple video feeds in a single take.

Solving the Post-Production Bottleneck

In traditional film and broadcast environments, production teams often face a difficult choice: shoot for the final pixel on set or shoot for post-production flexibility. Creating high-end In-Camera VFX (ICVFX) typically requires separate takes for tracking, chroma keying, and "clean" plates, leading to inflated schedules and rising costs. GhostFrame technology changes this equation by allowing the camera to capture multiple content experiences, all from a single take.

This breakthrough is made possible by the fact that LEDs can refresh significantly faster than a camera, and even faster than the human brain can see images. This physical discrepancy allows the LED wall to capture one or more sets of images while the naked eye only sees one. GhostFrame technology is specifically used to create on-set, real-time in camera VFX (ICVFX) workflows.

GhostFrame: Hidden Chroma Key for ICVFX

Hidden Chroma Key

GhostFrame adds a full chroma frame within your video feed, which enables real-time matte replacement or safety shots for post. This means you can record the final background and a green screen simultaneously, providing a "safety net" for any complex post-production needs without a second take.

GhostFrame: Embedded Camera Tracking for ICVFX

Embedded Camera Tracking

Markers can be embedded into the LED screen and hidden from the camera’s captured footage. Because these markers are digital and integrated into the sub-frames, they require zero installation time through the absence of physical markers—no more sticking dots on expensive LED panels.

GhostFrame enables MultiSource: multiple video feeds on your ROE Visual LED volume

Multiple Video Feeds

Up to four* unique video feeds can be captured simultaneously. This allows for multiple camera perspectives, varying backgrounds, or different lighting setups to be recorded in one go, drastically reducing the time needed for complex multi-cam scenes.

*The number of sub-frame slices is dependent on the panel type used. Please contact us for more information.

Comparing Workflows: Traditional vs. GhostFrame 

Feature Traditional ICVFX Workflow GhostFrame Enabled Workflow
Tracking Markers Physical stickers (visible to eye) Digital markers (hidden from camera)
Chroma Key Requires separate "Green Screen" take Simultaneous capture with final pixels
Camera Angles One perspective per take Up to 4 unique feeds/perspectives
Setup Time High (physical rigging needed) Minimal (software-controlled)

Multiple sources. One video feed. Multiple outputs.

GhostFrame works by displaying more than just the video feed on the LED panel. This magic makes it possible for professional cameras to capture one or more sets of images while the naked eye only sees one. Due to the fact that the LED panels have extreme processing power no work-arounds are needed. You can have all GhostFrame features while sending normal frame rates in 4K and 8K formats.

 

The Science of Multiple Hidden Sources

The magic of GhostFrame’s patented process makes it possible to show several sets of full dynamic images on an LED screen simultaneously within a camera’s production frame. One or multiple cameras can now capture more sets of images while the naked eye only sees one. The GhostFrame™ technology is based on advanced nanosecond alignment of video subframes and the camera shutter. By controlling the LED panels subframe output, cameras can align the shutter angle and capture the desired moment in time within a frame.

Show the talent where the AR object is located. Have hidden autocue or director cues on your LED wall, only visible in the studio. Nothing is impossible. Creating multiple hidden sources with GhostFrame in one video feed gives production teams the freedom to operate without restrictions and improves interaction between actors and digital assets.

GhostFrame Enhances Your Workflow

What if you could reduce both set-up and production time? Save time in post-production. Make your crew comfortable with high-end workflows without the need for additional hardware or losing processing and pixel capacity? What if you could work in a zero-latency environment? ROE Visual is the exclusive LED solution provider for GhostFrame, it does all that with LED enhancement. And More.
