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

ParameterTypeDefaultDescription
imageImage-Input image to convert to video
prompt_textString""Text prompt describing video motion and content
negative_promptString""Elements to avoid in the video
seedInteger0Random seed for generation
resolutionSelect”1080p”Output video resolution
durationSelect”5s”Length of generated video

​
Output

OutputTypeDescription
VIDEOVideoGenerated 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.
