The schematics below are two examples of how VIVE Mars fits the pipeline for Virtual Production using a green screen or LED wall.

• Rover

  Rover collects tracking data from VIVE Tracker (3.0) and relays it to Mars. See Rover for details.

• Lens Encoder

  If an external lens encoder is connected to the Rover, then the Rover will also transmit integer data as FIZ (Focus, Iris, Zoom) through Mars to the virtual production software.

• Mars

  Mars collects tracking data and encoder data from up to three Rovers and sends it to your PC either directly wired or through an IP router. See Mars for details.

• Genlock

  If an external Genlock (e.g: AJA GEN10 HD/SD Sync Generator) is connected, Mars would sync the tracking data to the frequency of the Genlock setting. This helps synchronize all connected machines to the same frame rate.

• Timecode

  If an external Timecode Generator (e.g: Ambient Recording ACN-CL Lockit) is connected, Mars would embed the master timestamp into tracking data. Some camera tracking protocols, such as Live Link, support the timecode metadata. This helps frame alignment in live or post-composition.

• Virtual Production Software

  Virtual production software receives tracking data through a messaging protocol, such as Live Link for Unreal, FreeD for Aximmetry, Zero Density, and Disguise. It renders out frames from the viewpoint of the tracked virtual camera. Virtual production software also receives the camera video feed from the video capture card, and then composite rendered frames and camera footage.

Example of VIVE Mars in an In-Camera VFX pipeline for LED wall.

One of the differences from Green Screen Real-time compositing, is for LED wall the Virtual Production software doesn’t receive the camera video feed, instead, the compositing is done in real-time when the camera is capturing the subject against an LED Wall.

• Genlock

  If an external Genlock (e.g: AJA GEN10 HD/SD Sync Generator) is connected, Mars would sync the tracking data to the frequency of the Genlock setting. This helps synchronize all connected machines to the same frame rate.

<aside> <img src="/icons/light-bulb_orange.svg" alt="/icons/light-bulb_orange.svg" width="40px" /> TIP: Most Virtual Production setups require synchronization over multiple machines. For an LED wall pipeline, Genlock is crucial to make sure the Camera, PC, and LED wall are in sync.

• Virtual Production Software

  Virtual production software receives tracking data through a messaging protocol, such as Live Link for Unreal, FreeD for Aximmetry, Zero Density, and Disguise. It renders out frames from the viewpoint of tracked virtual camera and outputs the rendered footage to projectors or LED walls.
