| format | COMBO | The format to save the video as. | |
| peak_nits | FLOAT | 400100–10000 | Peak brightness in nits. SDR white (100 nits) will be mapped to this target luminance in HDR. |
| itm_knee | FLOAT | 0.000–1 | Inverse Tone Mapping (Soft-Knee) threshold. 0.0 starts expansion from black. 0.8 preserves SDR midtones and applies expansion to highlights. |
| itm_exponent | FLOAT | 1.001–10 | Expansion curve exponent. 1.0 = Linear (punchy/bright), 2.0 = Quadratic (soft/natural), >2.0 = even softer transition. |
| loop_count | INT | 00–100 | Loop count. 0 = play once. For mp4/webm, this physically repeats the frames. |
