OptionalalgorithmOptionalpeakPeak luminance of the source in nits, e.g. 1000 for a PQ 1000-nit master.
OptionaltargetDesired output peak in nits. Default: 100 (SDR reference white).
OptionalparameterParametric tuning used by the mobius/reinhard/linear algorithms. Ignored by hable, clip and spline.
OptionaldesaturationDesaturation applied to out-of-range colours, 0-1. Default: 0.6
OptionalnormalizeCorrect the source primaries/transfer before tone mapping. Default: true. Set false if the input is already tagged correctly and you only want the transfer-function curve applied.
OptionaloutputTarget colour space for the SDR result. Default: 'bt709'
OptionalvideoOptionalaudioOptionalbinaryOptionalrequireReject the job unless the input actually looks like HDR. Default: true — tone mapping an already-SDR source is almost always a mistake.
Tone-mapping curve. Default: 'mobius' — the perceptually best of the built-ins for HDR→SDR at typical content levels.
