OCIODisplay

Uses the OpenColorIO library to apply a colorspace conversion to an image sequence, so that it can be accurately represented on a specific display device. The OCIODisplay node is based on the OpenColorIO library. For more information, see https://opencolorio.org.

Note: There are a number of NDK examples covering OCIO workflows that ship with the Nuke developer documentation, which can be found here:

Inputs and Controls

Connection Type	Connection Name	Function
Input	unnamed	The image sequence to receive the colorspace conversion.
mask	An optional image to use as a mask. By default, the colorspace conversion is limited to the non-black areas of the mask. At first, the mask input appears as a triangle on the right side of the node, but when you drag it, it turns into an arrow labeled mask. If you cannot see the mask input, ensure that the mask control is disabled or set to none.
