Kling V4 Multimodal Video Endpoint Overview
See how Kling V4 combines prompts and mixed media references in a controlled video workflow, with Atlas Cloud access pending endpoint release.
| Modality | Description |
|---|---|
| Kling V4 API (Coming Soon) | Kling V4 is planned to accept text prompts, images, videos, subject assets, and voice references for video generation through Atlas Cloud. Its confirmed creative profile covers Omni Reference, multiple keyframe direction, HDR video, synchronized stereo audio, and targeted editing. Use it for cinematic storytelling, campaign production, reference guided motion, and multilingual audiovisual content once the endpoint is released. |
Inside Kling V4: Longer Stories, Tighter Control
Kling V4 brings native 30-second generation, ten-keyframe direction, richer multimodal references, HDR video, stereo audio, and precise editing into a model family planned for unified Atlas Cloud access.
Kling V4 Native 30 Second Stories
Kling V4 supports native video generation from 3 to 30 seconds in one pass. Longer clips give actions, dialogue, scene changes, and emotional beats room to develop without stitching separate generations. Use the extended timeline for complete commercials, continuous takes, and short narrative sequences with a deliberate beginning, middle, and end without compressing story structure or chaining short outputs.
Ten Keyframes, One Directed Sequence
Place up to 10 keyframe images at chosen points across a Kling V4 timeline. Each frame anchors a character state, camera move, scene transition, or product reveal while the model generates the motion between milestones. When timing matters, creators can define important visual states instead of leaving every beat to a single prompt. This structure gives directors tighter control over pacing and multi shot progression.
Omni Reference Across 15 Assets
Omni Reference accepts up to 15 combined assets in one task, including as many as 10 images, 5 videos, and 7 subjects. Reference videos can guide performance, camera movement, and pacing, while images define characters, products, composition, or style. White model and depth map videos are also supported. The total remains capped at 15 even when individual category limits are higher.
Kling V4 Visuals and Stereo Sound
Kling V4 combines 720p, 1080p, and 4K output with 10-bit HDR at 1080p and 4K, plus a 21:9 ultrawide option. Two-channel stereo audio and tighter lip sync support dialogue across nine languages. On-screen text also works across nine languages and emoji. Choose this feature set for cinematic delivery and commercial footage with richer tonal detail.
Targeted Video Editing
Target specific parts of existing footage instead of rebuilding the entire take. Kling V4 can edit up to 5 input clips in one task, with a combined duration of up to 30 seconds, while supporting changes to expressions, camera angle, background, style, or dialogue. This control suits product swaps, localized revisions, and precise creative iteration.
One API Route for Kling V4
Atlas Cloud plans Day-0 Kling V4 access through one OpenAI-compatible key and a unified API alongside other models. A consistent authentication and billing layer will let developers evaluate the confirmed endpoint without creating another provider workflow. Transparent pay-as-you-go pricing will be published after launch, making this route suitable for controlled tests and variable production demand.
Kling V4 in a One Prompt Video Showdown
See how Kling V4, a leading rival, and the previous Kling generation interpret the same production-ready prompt across two distinct video challenges.
Create a 5-second cinematic video of a lone astronaut walking through a rain-soaked neon market at night. Begin with a wide establishing shot, then track smoothly behind the astronaut as vendors, umbrellas, holographic signs, and reflections pass through the frame. A small robotic bird launches from a stall, circles the astronaut, and lands on their shoulder. Preserve coherent architecture, natural walking motion, realistic rain interaction, stable character details, readable spatial depth, and consistent lighting. Use saturated cyan and amber highlights, shallow depth of field, subtle handheld movement, volumetric mist, and a restrained science fiction atmosphere. No text, logos, subtitles, cuts, or abrupt camera jumps.

Generate an 6-second photorealistic video of an elaborate glass dessert transforming into a living mechanical hummingbird on a sunlit restaurant table. Show the dessert cracking gradually as translucent wings unfold, tiny gears begin turning, and droplets of syrup slide across the glass surface. The hummingbird should hover, rotate once above the plate, and fly toward the camera while the background remains physically consistent. Emphasize accurate reflections, believable material transformation, fine mechanical motion, stable object geometry, controlled camera focus, and warm morning light. Use one continuous macro shot with a slow push-in. No text, logos, people, cuts, or sudden viewpoint changes.

Kling V4 Across the Production Pipeline
For teams moving from development to release, Kling V4 connects narrative previsualization, reference led campaigns, multilingual performance, directed motion, precise revisions, and multi format delivery.
Kling V4 Narrative Previsualization
Kling V4 uses up to ten keyframes to shape longer, structured sequences with synchronized sound. Filmmakers can map story beats, camera transitions, and continuous action before committing crews, sets, or postproduction budgets.
Reference Led Brand Campaigns
Combine product imagery, talent references, environments, and motion guidance through Kling V4 in one generation. Brand teams can create launch films, retail displays, and approved campaign variations while preserving visual direction across assets.
Multilingual Performance with Kling V4
With multilingual dialogue, lip sync, and two channel stereo audio, Kling V4 builds complete audiovisual performances. Localization teams can produce regional commercials, character scenes, musical spots, and product explainers within one coordinated workflow.
Camera Guided Production Planning
Feed a reference video to guide performance, camera movement, and pacing while changing the subject or setting. Directors and game teams can test action blocking, tracking shots, and transitions before costly production begins.
Precision Footage Revisions
Revise expressions, camera angles, backgrounds, or dialogue while Kling V4 preserves unaffected parts of existing footage. Production teams can localize approved shots, replace products, remove distractions, and refine scenes without rebuilding the take.
Multi Format Release Planning
Choose 21:9, 16:9, square, or vertical framing to carry one concept across screens. Creative teams can prepare cinematic masters, storefront loops, mobile campaigns, and social editions without reconstructing the core visual idea.

Kling V4 API Readiness and Creative Controls
Kling V4 is Atlas Cloud's page name for Kling 4.0, Kuaishou's native multimodal AI video model. It focuses on stable complex motion, controlled storytelling, mixed media references, synchronized stereo audio, and targeted video editing. Atlas Cloud serves the Kling V4 API now through one OpenAI-compatible key.
The model supports text to video, image to video, first and last frame control, Omni Reference, multiple keyframes, Creative Recreation, and targeted video editing. Editing controls can change subjects, expressions, movement, camera direction, backgrounds, and visual style while preserving unaffected parts of the scene.
Kuaishou lists text prompts of up to 8,000 tokens, images, videos, subjects, and voice references. Omni Reference accepts up to 15 combined assets, including up to 10 images, 5 videos with a combined duration of 30 seconds, and 7 subjects. Multiple keyframe mode supports up to 10 keyframe images.
Kuaishou lists generation from 3 to 30 seconds, resolutions of 720p, 1080p, and 4K, and aspect ratios including 21:9, 16:9, 1:1, 9:16, and automatic selection. The official product page still marks 10 bit HDR at 1080p and 4K, so confirm the active quality options in the Atlas Cloud endpoint schema.
No. Kuaishou's official user guide describes Omni Reference and Keyframes as separate entry points that cannot be combined in one generation task. Choose Omni Reference for mixed assets and subject consistency, or use Keyframes when specific visual states must occur at planned moments.
Yes. The full model supports two channel stereo audio with dialogue, singing, sound effects, ambience, and improved lip synchronization. Kuaishou lists Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French, and additional languages, together with multiple accents and dialects.
Choose the full model for videos up to 30 seconds, resolutions up to 4K, first and last frame control, and as many as 10 keyframes. Flash is designed for faster, frequent iteration and supports 3 to 20 second videos at 720p in 8 bit SDR, without first and last frame control or multiple keyframes.
Before retrying, verify the live model ID, endpoint, authentication header, request fields, media URLs, and supported parameter values against the Atlas Cloud documentation. Inspect the returned task status and error message first because an earlier asynchronous request may already have created a generation.
