OpenVPCal Plugin

The OpenVPCal plugin solves the problem of LED colour being recorded differently by the camera which is observing it, due to the inherent technical differences between the two technologies (a phenomenon called metameric failure).

Therefore the OpenVPCal plugin is useful for colour pipelines in any LED and camera scenario, such as in-camera visual effects pipelines or live events which use LED and cameras for IMAG or onwards transmission.

Use this plugin to generate calibration patterns, produce analysis data, calibrate LED walls, and create OCIO (OpenColorIO) configurations with colour calibration results. The created OCIO config can be loaded in Designer to apply the colour calibration results to LED walls.

Calibration is powered by OpenVPCal (developed by Netflix), and Disguise project control is provided through Designer Plugins.
