Kling Video O3 Pro Image-to-Video

Kling Video O3 Pro Image-to-Video is Kuaishou's flagship image animation model. Upload a reference image, describe the motion, and the model renders a cinematic video with physics-aware movement, temporal consistency, and optional synchronized audio — all at professional production quality.

Why Choose This?

Image-grounded generation Start from a reference image for precise visual control over characters, environments, and composition.
Start and end frame control Provide both a starting image and an end image to guide the motion arc and define exactly where the clip begins and finishes.
Physics-aware motion Understands real-world dynamics — fluid movement, fabric, hair, fire, and object interactions behave naturally throughout every frame.
Synchronized audio generation Enable the sound option to generate matching ambient audio and atmosphere alongside your video.
Multi-prompt support Chain multiple prompt segments to guide scene transitions and narrative flow within a single generation.
Element list control Lock in specific visual elements — characters, objects, or styles — to maintain consistency across the entire clip.

Parameters

Parameter	Required	Description
image	Yes	Starting reference image to animate (URL or file upload).
prompt	Yes	Text description of the motion, camera style, lighting, and atmosphere.
end_image	No	Optional ending frame image to define where the clip finishes.
duration	No	Clip length in seconds. Options: 5, 10.
sound	No	Whether to generate synchronized audio for the video. Default: off.
shot_type	No	Editing mode: intelligent (default, auto-determines scope) or customize.
multi_prompt	No	Additional prompt segments to guide scene transitions and progressions.
element_list	No	List of visual elements to maintain consistency throughout the clip.

How to Use

Upload your image — provide the starting reference image via URL or drag-and-drop.
Write your prompt — describe the motion, camera movement, lighting, and mood. Use the Prompt Enhancer for better results.
Add an end image (optional) — upload a second image to define the final frame of the clip.
Set duration — choose 5 or 10 seconds.
Enable sound (optional) — check to generate matching audio alongside the video.
Select shot_type (optional) — use intelligent for automatic scope, or customize for manual control.
Add multi-prompt segments (optional) — click Add Item to guide scene transitions.
Add element list items (optional) — see Notes below for how to use elements effectively.
Submit — generate, preview, and download your video.

Best Use Cases

Cinematic Photo Animation — Bring still photography to life with natural, physics-accurate motion.
Commercial & Brand Video — Animate product images and campaign visuals with professional-grade output.
Social Media Content — Generate portrait or square clips from reference images for maximum engagement.
Controlled Scene Generation — Use start and end frames to define precise visual transitions for storytelling.
Immersive Audio-Visual Content — Combine image animation with sound generation for fully atmospheric clips.

Pro Tips

Use a high-quality, well-composed source image — the model preserves and extends what it starts with.
Providing an end image significantly improves motion direction and narrative coherence.
Be specific in your prompt about camera movement (pan, zoom, dolly) and subject behavior.
Enable sound for scenes with fire, water, crowds, or ambient environments for a much more immersive result.
Start with a 5-second generation without sound to validate motion before committing to a longer, audio-enabled run.

Notes

Both image and prompt are required fields; all other parameters are optional.
Sound generation adds 25% to the base cost.
Ensure image URLs are publicly accessible; a preview thumbnail in the interface confirms the URL is reachable.
Using element_list: First use Kling Elements to generate your element and note its name and ID. Then simply write the element name naturally in your prompt, and enter the corresponding element ID in the element_list field. No special characters or syntax required.
Please follow Kuaishou's content usage policies when crafting prompts.

Kling Video O3 Pro Image To Video API — Frequently asked questions

What is the Kling Video O3 Pro Image To Video API?

Kling Video O3 Pro Image To Video is a Kuaishou model for video generation from images, exposed as a REST API on WaveSpeedAI. Kling Omni Video O3 Image-to-Video transforms static images into dynamic cinematic videos using MVL (Multi-modal Visual Language) technology. Maintains subject consistency while adding natural motion, physics simulation, and seamless scene dynamics. Supports audio generation. Ready-to-use REST API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Kling Video O3 Pro Image To Video API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/kwaivgi/kwaivgi-kling-video-o3-pro-image-to-video.

How much does Kling Video O3 Pro Image To Video cost per run?

Kling Video O3 Pro Image To Video starts at $0.56 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Kling Video O3 Pro Image To Video accept?

Key inputs: `prompt`, `image`, `duration`, `element_list`, `end_image`, `multi_prompt`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/kwaivgi/kwaivgi-kling-video-o3-pro-image-to-video.

How do I get started with the Kling Video O3 Pro Image To Video API?

Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.

Can I use Kling Video O3 Pro Image To Video outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (Kuaishou). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
