kling_generate_video_from_image
Animate a start image into a video or create a transition between start and end images. Describe the motion in a prompt.
Instructions
Generate AI video using reference images as start and/or end frames.
This allows you to control the video by specifying what the first frame
and/or last frame should look like. Kling will generate smooth motion between them.
Use this when:
- You have a specific image you want to animate
- You want to create a video transition between two images
- You need precise control over the video's visual content
At least one of start_image_url or end_image_url must be provided.
Returns:
Task ID and generated video information including URLs and state.Input Schema
