The Pika 2.2 Image to Video node connects to Pika’s latest 2.2 API to transform static images into dynamic videos. It preserves the visual features of the original image while adding natural motion based on text prompts.
Parameters
Required Parameters
| Parameter | Type | Default | Description |
|---|
| image | Image | - | Input image to convert to video |
| prompt_text | String | "" | Text prompt describing video motion and content |
| negative_prompt | String | "" | Elements to avoid in the video |
| seed | Integer | 0 | Random seed for generation |
| resolution | Select | ”1080p” | Output video resolution |
| duration | Select | ”5s” | Length of generated video |
Output
| Output | Type | Description |
|---|
| VIDEO | Video | Generated video |
How It Works
The node sends the input image and parameters (prompts, resolution, duration, etc.) to Pika’s API server as multipart form data. The API processes this and returns the generated video. Users can control the output by adjusting the prompts, negative prompts, random seed and other parameters.
