Gamut Mapping
Select the algorithm used to handle out-of-gamut colors during HDR processing. The available options depend on which pipeline is active.
Void Pipeline
When the Void HDR pipeline is active (use_void_hdr_pipeline = true), the following options are available:
| Algorithm | Internal Name | Description |
|---|---|---|
| Hanah | hanah | Hue-Aware Normalized Adaptive Hermite gamut compression |
| ACES 1.3 | aces_1_3 | ACES 1.3 gamut compression |
| Clip | clip | Hard clip out-of-gamut colors |
Default: hanah
Hanah Quality
When using the Hanah algorithm, a quality level controls the 3D LUT resolution:
| Quality | Description |
|---|---|
| Fast | Lowest resolution LUT, fastest computation |
| Medium | Balanced resolution |
| High | High resolution LUT (default) |
| Ultra | Maximum resolution, highest quality |
The quality setting is available under Advanced Gamut Mapping > Void > Hanah.
Libplacebo Pipeline
When using the libplacebo pipeline (use_void_hdr_pipeline = false), the standard libplacebo gamut mapping algorithms are available:
| Algorithm | Internal Name | Description |
|---|---|---|
| Clip | clip | Hard clip out-of-gamut colors |
| Perceptual | perceptual | Perceptual softclip mapping |
| Softclip | softclip | Softclip with knee point |
| Relative | relative | Relative colorimetric clipping |
| Saturation | saturation | Preserve hue and luminance |
| Absolute | absolute | Absolute colorimetric clipping |
| Desaturate | desaturate | Adaptive desaturation |
| Darken | darken | Darken out-of-gamut colors |
| Warn | warn | Highlight out-of-gamut in pink |
| Highlight | highlight | Highlight out-of-gamut by luminance |
Default: perceptual
The active algorithm is indicated in the menu. Selecting an option sets hdr.gamut_mapping_function in the config.
