Kling 3.0 Turbo Standard Image to Video

Kling 3.0 Turbo Standard Image to Video animates a single static first-frame image into 3–15 second 720p video. With composition-true subject preservation, native audio-visual lip sync, and up to 6-shot storyboard continuity, it suits product showcases, character performances, and high-volume short-form ad iteration. With multi_prompt, omitting top-level duration also allows shot totals of 1–2 seconds.

Why Choose This?

First-frame composition locked inTreat your still as the opening frame and keep subject look, wardrobe texture, and original framing intact as motion begins.
Native audio with faithful lip syncGenerate matching audio with the picture so dialogue lip shapes stay aligned—ready for delivery without a separate ADR pass.
Up to 6-shot storyboard continuityUse multi_prompt to stage 1–6 shots with framing, camera moves, and action while carrying character and setting cues across cuts.
Aspect ratio inherited from the stillOutput framing follows the first-frame image, so vertical posters, landscape product shots, or square art land in the matching canvas.
Flexible 3–15 second durationPick any integer length from 3 to 15 seconds (default 5) for hooks, product close-ups, or short ad beats.
Cost-efficient 720p Standard rateShip clear 720p clips at 17 credits per second ($0.085/sec)—built for high-volume drafts and short-form production.

Parameters

Parameter	Requirement	Description
image_urls	Required	String array with exactly one public image URL used as the first frame.
prompt	Optional	String, 1–2500 characters. Mutually exclusive with multi_prompt.
duration	Optional	An explicit duration must be 3–15 seconds and equal the shot total when multi_prompt is set. Omit it to use the shot total (1–15 seconds); without multi_prompt it defaults to 5 seconds. Default`Shot total / 5`
multi_prompt	Optional	1–6 shots, each with a nonblank prompt and optional duration of 1–15 seconds (default 5). Total duration must not exceed 15 seconds. Mutually exclusive with a nonblank prompt.
aspect_ratio	Optional	The output aspect ratio follows the input image; aspect_ratio has no effect on this endpoint.

How to Use

Provide the first-frame imageSet image_urls to exactly one publicly reachable image URL—this becomes the opening frame and composition anchor.
Write the motion promptOptionally add a prompt for camera moves, subject action, and sound cues; switch to multi_prompt for storyboard shots—the two are mutually exclusive.
Configure multi-shot storyboardingUse multi_prompt for 1–6 shots, each with a required prompt and optional duration defaulting to 5 seconds. The total must not exceed 15 seconds. Top-level duration can be omitted; if supplied, it must equal the total and be 3–15 seconds.
Set output durationChoose an integer length from 3 to 15 seconds; the Playground defaults to 5 seconds, and aspect ratio follows the first-frame image.
Review the cost and runCheck the cost shown on the Run button, confirm the first frame and prompt, then click Run.
Preview and download the videoWhen the task finishes, preview picture and sound in the output panel, then select Download video to save the 720p result.

Best Use Cases

E-commerce product still animationTurn product hero shots into short showcase clips with camera motion and ambience for detail pages and feed ads.
Character dialogue and lip-sync performanceStart from a character portrait or key art and generate talking or reaction shots with natural lip sync for hooks and virtual hosts.
Concept-art multi-shot adsUse one key visual as the opener, then stage close-up-to-wide beats with multi_prompt to land a full short-ad rhythm in one run.
Vertical social content draftsUpload a 9:16 first frame so the clip inherits vertical framing for Reels, Shorts, and similar short-form layouts.
Fast 720p creative iterationValidate motion and storyboard choices at the Standard rate, then move to a higher-resolution tier when the direction is locked.

Pro Tips

Start with a clear subject and clean framing, and name face, wardrobe, and materials in the prompt so identity cues stay explicit.
Describe motion from the pose already in the still—for example, “push along the body, then pull back as the car enters a rainy street”—instead of fighting the original composition.
When using multi_prompt, label each shot’s duration and framing and keep character/setting descriptors consistent across cuts.
For lip-synced speech, write the spoken line and tone in the prompt; native audio is generated with the picture.
For vertical delivery, upload a vertical first frame so ratio follows the image; use 3–5 seconds for a single beat, or 8–15 seconds for multi-beat stories.

Usage notes

Kling 3.0 Turbo Standard Image to Video requires exactly one public image in image_urls as the first frame; prompt and multi_prompt are mutually exclusive guides for motion.
Output is fixed at 720p, with aspect ratio inherited from the first-frame image; duration can be 3–15 seconds (default 5).
Billing is by output seconds at 17 credits/sec ($0.085/sec); the default 5-second clip costs 85 credits ($0.425).
After an API submission, save the returned task_id to query progress and retrieve the final video URL.

Kling 3.0 Turbo Standard Image to Video API frequently asked questions

What is the Kling 3.0 Turbo Standard Image to Video API?

Kling 3.0 Turbo Standard Image to Video is a Kuaishou (Kling AI) model for animating a single first-frame image into short video. It generates 720p clips from exactly one first-frame image plus an optional prompt, with composition-true subject preservation, native audio-visual lip sync, and up to 6-shot storyboard continuity. Built on Kling 3.0 Turbo’s high-throughput generation and multi-shot consistency, it keeps the source subject identity and framing intact while adding directed motion and matching dialogue sound. You can call it programmatically or try it from the playground above. Without multi_prompt, duration is 3–15 seconds. With multi_prompt, omitting top-level duration also allows a shot total of 1 or 2 seconds.

How does Kling 3.0 Turbo Standard Image to Video use the first frame?

Provide exactly one public image URL in image_urls; that still becomes the opening frame and composition anchor. Optionally add a prompt for camera, action, and sound, or switch to multi_prompt for storyboard shots—see the Parameters table on this page for field details.

How does Kling 3.0 Turbo Standard Image to Video keep character consistency?

The model locks face, wardrobe, and framing from the first-frame image and carries character and setting cues across multi-shot cuts. Use a clear subject still and spell out appearance and clothing in the prompt to further stabilize identity across shots.

How do I configure multi_prompt on Kling 3.0 Turbo Standard Image to Video?

multi_prompt accepts 1–6 shots. Each shot needs a nonblank prompt and an optional integer duration of 1–15 seconds, defaulting to 5. The sum must not exceed 15 seconds. Omit top-level duration to use that sum, including totals of 1 or 2 seconds. If supplied, top-level duration must be an integer from 3 to 15 and equal the sum. multi_prompt cannot be combined with a nonblank top-level prompt. Edit storyboards in JSON mode; switching to the form keeps JSON mode and all shot settings.

How does aspect-ratio inheritance work on Kling 3.0 Turbo Standard Image to Video?

The output aspect ratio follows the input image; aspect_ratio has no effect on this endpoint.

Does Kling 3.0 Turbo Standard Image to Video include native audio?

Yes—results include native audio-visual sync with dialogue lip shapes aligned to speech. Write spoken lines, tone, or ambience cues in the prompt to further guide the soundtrack.

How should I choose Kling 3.0 Turbo Standard Image to Video?

Pick this Standard tier when you already have a still and want fast, cost-efficient drafts at fixed 720p (17 credits/sec). For the same first-frame workflow at higher delivery clarity, use Kling 3.0 Turbo Pro Image to Video (fixed 1080p); if you have no still and start from copy alone, choose the matching Text to Video variant.
