|---|---|
| Menu | AI › AIUpscale |
| **Names in each format** | |
| .oink comp (JSON) | `"type": "OC_N_aiupscale"` |
| .nk script | none: written as an Oink node |
| Python | `nuke.createNode("OC_N_aiupscale")` |
| Assistant (MCP) | `create_node(type="AIUpscale")` |
| Tab search | `aiupscale`, or its initials `aiu` |

## Knobs

Panel tab **Aiupscale**, in panel order.

| Knob | Label | Type | Default | Range / values | .nk knob | Description |
|---|---|---|---|---|---|---|
| `model` | model | menu | `AUTO` | AUTO (Auto (by free GPU memory)), REALESRGAN (Real-ESRGAN (fast)), SEEDVR2 (SeedVR2 3B (video)) |  |  |
| `scale` | scale | menu | `2` | 2 (2x), 4 (4x) |  |  |
| `tile` | tile | float | `512` | 0 to 8192 (integer) |  | Tile size in input pixels (0 = whole frame) |
| `temporal_window` | temporal window | float | `5` | 1 to 21 (integer) |  | Frames seen together by video models (4n+1) |
| `detail` | detail | float | `1` | 0 to 1 |  | 0 = plain Lanczos (fidelity), 1 = full model detail |
| `preserve_highlights` | preserve highlights | bool | `true` |  |  | Model sees 0..1 only; values above 1 and below 0 ride along as a Lanczos residual |
| `encoding` | encoding | menu | `REINHARD` | REINHARD (reinhard), LOG (log), SRGB (srgb) |  |  |
| `exposure` | exposure | float | `0` | -6 to 6 |  | Stops before encoding (fixed per shot), removed after |
| `peak` | peak | float | `16` | 1 to 1000 |  | Top of the encoded range when highlights are not preserved |
| `color_correction` | color correction | menu | `LAB` | LAB (lab), WAVELET (wavelet), NONE (none) |  |  |

### Other knobs (Python, .nk and the assistant; not on the panel)
