Prompt
A Wes Anderson style movie trailer with symmetrical framing and pastel colors. Opening: a perfectly centered shot of a grand pink hotel facade with teal shutters. A bellboy in a pillbox hat pushes a luggage cart precisely down the center of a hallway. Quick lateral tracking shots: a mustachioed concierge stamps a passport, twin sisters in matching yellow dresses ride a tandem bicycle through a village square, a detective examines a painting through a magnifying glass while standing in an absurdly tiny elevator. Every shot is perfectly balanced and color-coordinated in pastels. Final symmetrical shot of the entire cast standing in a row on the hotel steps. Text in a vintage serif font: "KLING V3 OMNI VIDEO" then "NOW ON REPLICATE". Whimsical harpsichord music, the sound of a bell ding.

Prompt
A lavish period drama movie trailer set in 18th century Versailles. Opening: a sweeping crane shot over manicured gardens with fountains at golden hour. Cut to a grand ballroom filled with dancers in elaborate silk gowns and powdered wigs, candlelight from enormous chandeliers. A mysterious woman in a crimson dress locks eyes with a nobleman across the room. Quick cuts: secret letters being passed, a duel at dawn in the mist, tears on a beautiful face. Final shot: the woman stands alone on a balcony overlooking Paris at sunset. Elegant gold text fades in: "KLING V3 OMNI VIDEO" then "NOW ON REPLICATE". Sweeping orchestral strings, harpsichord notes, dramatic crescendo.

About Kling v3 Omni
TL;DRAs of September 23, 2026
Kling v3 Omni is a model by Kuaishou (Kling) in the Video generation category. On Railwail, Kling v3 Omni costs $0.2688 per second of video. Depending on the settings, the price ranges from $0.2016/s to $0.504/s. A default run of 5 seconds costs $1.344. Supported aspect ratios: 16:9, 9:16, and 1:1. Possible lengths: 3, 5, 10, or 15 s.
Background
About Kuaishou Technology
Founded 2011 · Beijing, China
Kuaishou Technology (founded 2011 by Su Hua and Cheng Yixiao) operates one of China's two dominant short-video platforms and runs the KLING AI lab. Following the success of Kling 1.x and Kling v3, the team released Kling v3 Omni in 2025 as the multimodal-conditioning variant of v3. Omni accepts not only text and a single image but also audio reference, video reference, character-reference images, sketches, depth maps and pose skeletons, making it the broadest conditioning surface among Chinese video models. Omni is exposed through klingai.com, the Kling Studio editor and the Kling API.
Diffusion Transformer (DiT) with multimodal conditioning adapters
Kling v3 Omni shares the same core DiT denoiser as Kling v3 but adds a suite of conditioning adapters that inject heterogeneous control signals into the diffusion backbone. The model accepts text prompts (bilingual LLM encoder), first frame, end frame, subject-reference images (for locked identity), pose / skeleton videos (for motion transfer), depth maps (for 3D-aware control), sketches (for layout), audio reference (for music-driven motion and lip-sync) and short video references (for style transfer). Each modality is encoded by a dedicated adapter network and merged via cross-attention layers into the 3D spatio-temporal latent stream. Joint audio-video diffusion produces synchronized sound, including lip-sync to a provided dialogue audio track. Training uses paired multimodal-conditioning data including motion-capture libraries, sketch-to-video pairs and music videos.
Parameters
Undisclosed
Capabilities
Text-, image-, pose-, sketch-, depth-, audio- and video-reference conditioning
Lip-sync to a user-provided dialogue audio track
Motion transfer from a pose / skeleton video
Subject-reference for locked character identity
Sketch- and depth-controlled layout for storyboards
1080p / 30 fps, native synchronized audio
Available via Kling Studio and API
Strongest conditioning surface among Chinese video models
Best for: animation studios, lip-sync content, motion-capture-driven workflows.
Training & license
Closed corpus including platform video, licensed footage, motion-capture libraries, sketch / depth annotation pairs and music videos with dense multimodal captions.
License: Proprietary commercial licence via Kling AI / Kuaishou terms.
Safety testing: Same filters as Kling v3 plus deepfake / impersonation guards on lip-sync inputs; subject to Chinese CAC algorithmic-content rules.
Known limitations
Complex conditioning workflows can be brittle
Heavy political and public-figure moderation
Higher per-clip cost than vanilla v3
Audio sync is short-form and English/Chinese-leaning
