Kling 3.0 Image-to-Video: Core Parameters and Use Case Illustration

An image-to-video clip actually generated with the Kling 3.0 image-to-video author route, used to demonstrate how the most critical input parameters of this route affect the final video: image_urls supports 1 image (first frame only) or 2 images (first frame + last frame), duration takes a value between 3 and 15 seconds, resolution can be 720p / 1080p / 4K, sound controls whether native sound effects and ambient audio synchronized with the visuals are generated, and prompt is used to constrain the motion style and visual style. This piece provides two images: one is a still-life product composition for the first frame, and the other is the same scene from a different angle for the last frame, thus forming an interpretable camera displacement; duration is set to 8 seconds, resolution to 1080p, and sound is off, making it easy for developers to compare the relationship between parameters and output. The value of image-to-video lies in using existing visual materials (storyboard drafts, product images, poster visuals) as anchors, letting the model fill in motion and physical behavior while maintaining subject consistency. It is suitable for rapid production of advertising and brand short films, e-commerce product showcase videos, batch video conversion of social vertical-format assets, and early-stage storyboard previews for film and television animation. If dialogue content with lines and lip-sync matching is required, the route configuration in the model family that supports native audio should be used instead; this entry focuses on the image-to-video parameters themselves and does not extend to capabilities not declared in the schema.
