# BerniniConditioning - ComfyUI Built-in Node Documentation

> Complete documentation for the BerniniConditioning node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The BerniniConditioning node prepares video and image conditioning data for the Wan2.2-A14B model. It encodes source videos, reference videos, and reference images using the provided VAE, then attaches them to the conditioning data for in-context generation tasks. The task is automatically inferred from which inputs are connected.

## Inputs

| Parameter          | Description                                                                                                                                   | Data Type    | Required | Range                 |

| `height`           | Height of the output latent (default: 480)                                                                                                    | INT          | Yes      | 16 to 8192 (step: 16) |

| `batch_size`       | Number of videos to generate in a single batch (default: 1)                                                                                   | INT          | Yes      | 1 to 4096             |
| `source_video`     | Source video to edit or restyle (v2v, rv2v). Resized to width/height and trimmed to length.                                                   | IMAGE        | No       | -                     |
| `reference_video`  | Video to insert into the source video (ads2v).                                                                                                | IMAGE        | No       | -                     |
| `reference_images` | Reference images injected as in-context tokens (r2v, rv2v). Up to 8 images can be provided.                                                   | IMAGE        | No       | 0 to 8 images         |
| `ref_max_size`     | Max size for the long edge of reference\_video and reference\_images. Resized with preserved aspect ratio and snapped to 16px (default: 848). | INT          | No       | 16 to 8192 (step: 16) |

**Note:** The task is inferred from which inputs are connected:

* No inputs connected → text-to-video (t2v)
* `source_video` only → video-to-video (v2v)
* `source_video` + `reference_images` → reference-guided video editing (rv2v)
* `reference_images` only → reference-to-video (r2v)
* `source_video` + `reference_video` → insert image/video into video (ads2v)
