Inputs (8)
| Name | Type | Default | Description |
|---|---|---|---|
| video | IMAGE | — | |
| reference_image | IMAGE | — | |
| reference_frame_index | INT | 00–9999 | 0-based index of the frame in the video batch that corresponds to the reference_image. |
| method | COMBO | mkl | 9 options: mkl, reinhard_lab, linear_rgb, histogram, reinhard_lab_gpu, hm-mkl-hm, +3 |
| strength | FLOAT | 1.000–1 | Blend between original (0.0) and fully corrected (1.0). |
| propagation | COMBO | uniform | uniform = same correction every frame. falloff = correction tapers with distance from the anchor frame. |
| falloff_radiusopt | INT | 301–9999 | [falloff mode] Frames from the reference frame at which correction strength reaches zero. |
| falloff_gammaopt | FLOAT | 1.00.1–4 | [falloff mode] Curve shape. 1.0 = linear. >1 = fast initial drop. <1 = slow initial drop. |
