# WanCameraImageToVideo - ComfyUI Built-in Node Documentation

> The WanCameraImageToVideo node prepares conditioning and latent data for camera-controlled video generation from images.

The WanCameraImageToVideo node prepares conditioning and latent data for camera-controlled video generation from images. It takes positive and negative conditioning prompts, along with optional inputs such as a starting image, CLIP vision output, and camera conditions, and outputs updated conditioning plus an empty latent tensor ready for a video model to fill in.

## Inputs

| `start_image`        | Optional starting image to initialize the video sequence. When provided, only the first `length` frames are used, and the image is resized to match the specified `width` and `height`. The first frames of the sequence are encoded into the latent and a mask is applied to blend the starting frames with generated content. | IMAGE                  | No       | -                     |
| `camera_conditions`  | Optional camera embedding conditions for video generation.

**Note:** When `start_image` is provided, the node sets `concat_latent_image` and `concat_mask` values on both `positive` and `negative` conditioning. The `camera_conditions` and `clip_vision_output` parameters are optional, but when provided, they modify the conditioning for both the positive and negative prompts.
