Kling 2.6

Audio-Visual VideoText or ImageOptional Sound

Kuaishou’s Kling Video 2.6 generates short video and optional synchronized audio in one pass. Through APIXO, developers can create from text or one starting image, add an optional end frame, select five- or ten-second output, and choose between silent generation or speech, effects, ambience, and music.

Capabilities

Audio responds to the scene, not an isolated track

Simultaneous Audio-Visual Generation

Kling Video 2.6 generates visuals and sound within the same model pass. This enables closer coordination between visible action, vocal rhythm, environmental events, and the timing of the resulting soundtrack.

Multiple Sound Types

Direct standalone or combined speech, dialogue, narration, singing, rap, music, ambient sound, and effects in the prompt. APIXO’s sound toggle determines whether the requested output includes generated audio.

Chinese and English Voices

Kling Video 2.6 supports dialogue-led scenes involving multiple characters, including interviews, scripted exchanges, and short performances. Speaker attribution, pronunciation, and synchronization should still be reviewed before publishing.

Semantic Sound Alignment

The model interprets textual descriptions, colloquial expressions, and short story scenarios to coordinate sound with visual events. Explicitly describe who speaks, what happens, and when each sound should occur.

Layered Audio Scenes

Combine voice with environmental ambience and event-specific effects instead of producing a single isolated sound. This supports compact scenes where atmosphere, action, and spoken content all contribute to the result.

Start-and-End Frame Control

Through APIXO’s image-to-video workflow, one image establishes the starting composition and an optional second image can guide the intended end frame. The model generates the intervening motion rather than performing deterministic interpolation.

APIXO Modes

Generate freely or anchor the opening composition

Text-to-Video

Generate from a required prompt without source images. APIXO exposes 1:1, 9:16, and 16:9 aspect ratios for this workflow, supporting square, vertical, and landscape audiovisual scenes.

Prompt-Led Scene

Image-to-Video

Supply one image as the starting frame and optionally a second image as an end frame. APIXO does not forward aspect-ratio selection in this mode, so prepare source images for the intended composition.

Narrated Product Videos

Generate product demonstrations with narration, environmental sound, and action-specific effects in one pass. Use an image-led workflow when an approved product composition should anchor the shot, then verify labels, geometry, speech, and claims.

Social Content

Dialogue and Performance Clips

Create interviews, short scripted exchanges, comedy concepts, singing, or rap performances. Kling Video 2.6 supports generated dialogue, but speaker attribution, pronunciation, timing, and lip synchronization should be reviewed before publishing.

Story Development

Sound-Aware Scene Prototypes

Prototype how camera movement, physical action, dialogue, ambience, and effects interact within a five- or ten-second scene. This helps teams evaluate the full audiovisual idea before separate production or postproduction.

Visual Transitions

Framed Image Animation

Animate one approved image or guide the clip toward an optional ending frame. Add sound when the transition needs synchronized atmosphere or effects, or generate silently for an existing audio workflow.

Integration Notes

Separate documented controls from later Kling features

APIXO constraints

APIXO exposes one Kling 2.6 variant rather than Standard, Pro, Master, or Turbo quality tiers.

Every request requires a prompt, a 5- or 10-second duration, and an explicit sound value.

Text-to-video accepts aspect-ratio selection; image-to-video derives composition from its source image.

Image-to-video accepts one starting image and one optional end-frame image.

The route does not expose video input, motion control, extension, editing, or arbitrary multi-reference generation.

APIXO supports status polling or webhook delivery; Longer clips with generated audio typically require more processing time; callback delivery is preferable for production workloads.

Kling 2.6 questions

APIXO maps this route to Kuaishou’s Kling Video 2.6 and does not expose a Standard, Pro, Master, or Turbo quality-tier selector.

Silent output costs 66 Credits per generated second: 330 Credits for five seconds or 660 Credits for ten. With model-generated audio enabled, the rate is 132 Credits per second: 660 Credits or 1,320 Credits respectively.

Yes. Kuaishou officially supports speech, dialogue, narration, singing, and rap alongside effects and ambience. The model generates Chinese and English voices, while APIXO exposes this capability through the required sound toggle and prompt.

No. APIXO does not expose audio-upload or video-input fields for this route. Kling 2.6 generates requested sound from the prompt; it does not accept a prerecorded voice, soundtrack, motion clip, or source video here.

Check identity, anatomy, hands, embedded text, object contact, rapid movement, transitions, dialogue accuracy, speaker assignment, pronunciation, and audio synchronization. Multi-character scenes and dense sound directions may require several generations.
