General Settings

Colour Management Mode option

Select the type of colour management tool to use.

Bit-Depth option

Select the output bit-depth. Select "16-bit fp" or "32-bit fp" when converting to a scene-linear colour space.

Tagged Colour Space option

Select the colour space to tag your media with. This does not alter pixel values, but it does affect how the viewports show the media.

Invert

Invert the colour transform to convert from the original destination back to the original source colour space. In Custom mode, available in the Colour Management node, you may also invert individual component transforms by clicking in the Invert column to toggle it.

Export

Export this transformation as a single CTF file. This may be used in other applications that use a sufficiently recent version of OpenColorIO.

Pixel Sampler

Click on this box and then drag the cursor through the image to sample values.

Colour Transform details

Shows descriptive information about the transform including the mathematical operations applied. Each OCIO Transform in the processing chain is shown. Click the plus icon to expand and show the transform parameters.

View Transform settings

Tagged Colour Space option

Select "From Source" to use the tagged colour space of the input or select another value to override it.

View Transform option

Before selecting a View, first set the Tagged Colour Space and Display since the list of Views is filtered based on those values. Select "From Rules" to use the highest priority OCIO View for the Tagged Colour Space and Display. Use the "All Views" sub-menu to access all the views in the config for the selected display, not filtered by the OCIO viewing rules.

Display option

Select the Display from the OCIO config that you want to use. The "Current Video Preview Device" option is taken from the Colour Management Preferences. If the display has a corresponding display colour space in the config, that will be used to tag the output. Otherwise, the output will be tagged with the colour space specified in the view.

Input Transform settings

Input Colour Space option

Select the source colour space of your media. "From File or Rules" leverages the File Input Rules set in Colour Management Preferences. However, metadata from the file takes precedence over the File Input Rules. Named Transforms from the config will be included in this menu if they have the 'file-io' category set.

Working Space option

Select the destination colour space for the transform. "From Project" takes the Working Space value from the Colour Management Preferences. By default, the list of items is filtered based on the 'working-space' category tag assigned to each colour space.

Colour Transform Settings

Import

Open the file browser to import a LUT or colour transform using OpenColorIO.

Custom

Add

Add a new row to the end of the transform chain. Click in the Type column to select or change the transform type, and then click in the Transform column to select a transform.

Delete

Remove the selected transform from the chain.

Up

Move the selected transform earlier in the chain.

Down

Move the selected transform later in the chain.
