ASC CDL: controls, files and reversibility
OCIOCDLTransform applies ASC CDL: per-channel Slope, Offset and Power plus overall Saturation. This compact primary grade can be authored in Controls, saved to a file and reproduced in an agreed color pipeline.

Overview
What OCIOCDLTransform does
OCIOCDLTransform applies ASC CDL: per-channel Slope, Offset and Power plus overall Saturation. This compact primary grade can be authored in Controls, saved to a file and reproduced in an agreed color pipeline.
A CDL does not automatically identify input gamut or gamma. The same values produce different results on linear and log data. Matching requires the same input domain, placement, operation order and agreed range handling.
The supplied capture shows File mode, so the manual controls are hidden. The Blackmagic manual separately documents Slope, Offset, Power and Saturation; they are added to the Inspector without removing the ten original topics.
Reverse is useful for testing a pair, not for recovering lost detail. Zero slope, zero saturation or clipped values can make original colors indistinguishable. The output remains an image; CDL export uses a button, not a separate Flow output.
When to use it
Apply a fixed CDL to its intended plate.
Create and export a manual SOP/Saturation grade.
Test whether a round trip is valid.
