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 (3-15, default: 5).
sound	No	Whether to generate synchronized audio for the video. Default: off.
shot_type	No	Editing mode: customize (default) or intelligent.
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.
Add an end image (optional) — upload a second image to define the final frame of the clip.
Set duration — choose 3 to 15 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.

Pricing

$0.42 per second of video, regardless of whether audio is on or off.

Duration	Cost
3s	$1.26
5s	$2.10
10s	$4.20
15s	$6.30

Best Use Cases

Cinematic Photo Animation — Bring still photography to life with natural, physics-accurate motion in 4K.
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 short duration to validate motion before committing to a longer run.

Notes

Both image and prompt are required fields; all other parameters are optional.
Duration range: 3 to 15 seconds.
Audio does not affect pricing — $0.42 per second regardless.
Ensure image URLs are publicly accessible.
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.
Please follow Kuaishou's content usage policies when crafting prompts.
