Current Gamut
Declares the gamut in which the incoming values are expressed.
Correct input declaration is essential because gamut boundaries depend on the source space.
Constrain colors to a target gamut
Constrains out-of-gamut colors from a declared current gamut/gamma into a selected limiting gamut while preserving as much useful color as possible.
GamutLimiter is used when highly saturated or wide-gamut values must be kept inside a smaller delivery or processing gamut without simply clipping every channel independently.
Overview
GamutLimiter is used when highly saturated or wide-gamut values must be kept inside a smaller delivery or processing gamut without simply clipping every channel independently.
Place a boundary around the legal color volume and push colors that escape that boundary back inside it.

Declares the gamut in which the incoming values are expressed.
Correct input declaration is essential because gamut boundaries depend on the source space.
Sets Current Gamut to Rec.709.
Sets Current Gamut to DaVinci Wide Gamut / ACES / ACEScg.
Sets Current Gamut to Camera Gamuts.
Declares the incoming transfer function.
Choose Linear, log or display gamma according to the actual pipeline stage.
Uses Linear for current gamma.
Uses Log Profiles for current gamma.
Uses Gamma 2.2 / 2.4 / 2.5 / 2.6 for current gamma.
Selects the gamut boundary to enforce.
Typical targets include Rec.709, P3 or another known delivery gamut.
Sets Limit Gamut to Rec.709.
Sets Limit Gamut to P3 / DCI / ACEScg / Wide gamuts.
Handles transparent premultiplied pixels safely.
Enable for graphics or keyed elements when edge colors are affected.
Practical setup
Confirm the current gamut and gamma.
Select the legal or desired limiting gamut.
View the most saturated frames in the shot.
Compare the limited result against hard clipping.
Keep the limiter close to the stage where the target gamut requirement actually matters.
Examples
Constrain a wide-gamut composite before a Rec.709 output path.
Keep neon motion graphics within a display gamut.
