Kling 2.6 generates video with synchronized audio. Dialogue, tone, and sound effects are produced with the footage in a single request.
With Kling 2.6 on Pollo API, developers can add text-to-video and image-to-video generation to their products, guide start and end frames, choose 5 or 10 second clips, and toggle matching audio per call.
Key Features of Kling 2.6 API
Synchronized Audio and Visuals
Speech, ambient tone, and sound effects are produced synchronized with the action, with lips and gestures timed to the audio.
Directed Sound Control
Prompts can steer dialogue lines, emotional tone, and specific effects, letting a talking character or an impact moment carry the exact sound you describe rather than generic filler.
Start and Tail Frame Guidance
Supplying a first image and a tail image lets the model interpolate a controlled path between them, so transitions and product reveals resolve on the frame you intend.
Text and Image Guidance
Generation starts from a written prompt or an image URL, so idea-first scripts and asset-first shots both become moving clips within the same model.
Flexible Framing and Length
Clips render in 16:9, 9:16, or 1:1 for landscape, vertical, and square feeds, at 5 or 10 seconds, matching short-form placements without post-crop reframing.
Use Cases of Kling 2.6 API
Talking Character Clips: Generate a subject who speaks a scripted line with matching mouth movement and tone, useful for avatar and dialogue-driven apps.
Sound-Effect Scenes: Produce moments where the audio is the point, such as a bell ringing, rain on a tin roof, or footsteps on gravel.
Vertical Social Videos: Render 9:16 clips with built-in audio for feeds where sound-on autoplay decides whether a viewer stays.
Guided Transitions: Use a first and tail image to control how a scene starts and ends, ideal for reveals, before-and-after shots, and loops.
Image-Led Animation: Animate a still photo into a short moving shot with fitting ambience, preserving the original subject and framing.
Narrated Explainers: Turn a written script into a spoken short where voice and on-screen action stay aligned for tutorials and product walkthroughs.
Ambient Mood Pieces: Create atmospheric clips where wind, water, or crowd sound sets the tone alongside the visuals.
How to Use Kling 2.6 API
Get an API Key: Create a Pollo API account and generate your API key from the developer dashboard.
Choose the Model: Send requests to the Kling 2.6 endpoint at /generation/kling-ai/kling-v2-6.
Add Your Inputs: Provide a prompt for text-to-video, or an image URL for image-to-video, optionally an imageTail, then set length (5 or 10), aspectRatio, and generateAudio.
Generate and Retrieve: Submit the task, poll the returned task status, and download the finished clip once processing succeeds.
Prompting Best Practices for Kling 2.6 API
Write for both channels at once. Describe what happens on screen, then name the spoken line, tone, or effect you want, so the model has a clear target for audio and motion together.
A Simple Prompt Formula
Subject and setting + specific action + spoken line or sound cue + tone or mood + camera and framing
What You Should Notice
Name the Sound: State the dialogue, effect, or ambience directly so the generated audio matches your intent instead of defaulting.
Keep Speech Short: Fit spoken lines to 5 or 10 seconds so delivery and lip movement stay natural within the clip length.
Set the Two Frames: When using a tail image, make the start and end states clearly different so the interpolation has a direction to follow.
Pick Framing Early: Choose 16:9, 9:16, or 1:1 up front so composition suits the target feed from the first render.
One Audio Focus: Center each clip on a single voice or effect so the soundtrack reads clearly rather than competing.
Example Prompts
Scripted Dialogue
"A librarian looks up from a book and says warmly, 'You made it just in time.' Soft page-turning and a distant clock tick in the background. Medium shot, quiet indoor light, gentle push-in, realistic style."
Sound-Driven Moment
"A blacksmith strikes glowing metal on an anvil, sparks scattering with each rhythmic clang. The hammer rings sharp and metallic. Side-on shot, dim forge glow, slight camera shake, gritty realistic style."
Guided Frame Transition
"Start on a folded paper crane on a windowsill; end with it mid-flight across a bright room. Soft flutter of paper and a light breeze. Static camera, morning light, clean realistic style."
Ambient Vertical Clip
"A street musician plays a slow melody on an accordion at dusk, coins clinking as a passerby drops one in. Vertical 9:16 framing, warm streetlight glow, camera slowly rising, natural realistic style."
