Purpose

 

This node allows to associate CDL metadata (basic color grading parameters  based on the ASC-CDL standard (Offset, Power, Slope and Saturation).

Note that this node will not render new media files by itself, instead it will define the CDL color transformations  to be applied by posterior encoder nodes with render capability.

Inputs

 

input_1: Connect the media file to receive the CDL transformations.

 

 

Outputs

 

Output: The input media with the CDL applied as metadata (to be used by posterior nodes).

Node specific properties

 

Source (Auto, From Metadata, From sidecar, Custom):

 

Auto: Try to find CDL information from any of the next methods, in that order.

 

From Metadata: Select CDL information defined by previous nodes upstream, and pass it to the output.

 

From sidecar: Load CDL information from the CDL sidecar file (that is, a file with the same name and location as the input media files, but with a .cc extension added to the original name), and pass it to the output.

 

Example:

 

Source media file: test.mxf

CDL file: test.mxf.cc

 

Custom: Permits to define CDL metadata values to be passed to the output. When Custom is selected the next properties will appear:

 

Offset: Offset to be applied to RGB channels.

 

Slope: Slope to be applied to RGB channels.

 

Power: Power to be applied to RGB channels.

 

Saturation: Saturation value to be applied.

 

The Custom  mode is also convenient as a placeholder to associate CDL values obtained from custom Python nodes executed upstream.
