The atmosphere is electric: street vendors, kids playing football, and local dancers vibing in the background. The city feels loud, alive, and unapologetic. Subject: A Black male rapper in raw streetwear — fitted cap, graphic tee, worn sneakers, simple chain. He stands front and center, locked in with the camera, body moving naturally to the rhythm, commanding the street like it’s his stage. Audio: [Male rapper, high-energy, gritty voice] Rapping over a hard street beat blended with Brazilian percussion: “Painted walls talk loud, yeah, they know my name, Came up from the block where the heat stay flame. City never soft, had to hustle, stay sharp, Turned struggle into fire, now I’m leavin’ my mark. Bass hit heavy, feel the ground when I step, From these streets to the world, yeah, I’m reppin’ respect.” Background: Heavy bass layered with live drum hits, claps, and subtle street noise — bikes passing, distant voices, raw urban texture. Camera: Rapid cuts between tight close-ups of his face and hands, wide shots of the colorful murals, quick flashes of dancers and street life. Handheld movement keeps it gritty and real, ending on a strong close-up as the beat hits.",

Kling 2.6 Pro: Image-to-Video Model (with Native Audio)
What is Kling 2.6 Pro?
Kling 2.6 Pro is an advanced image-to-video generative AI model that turns a single still image plus a text prompt into a short, cinematic clip—with integrated, native audio. Provide an image_url as the visual starting frame and describe the scene in prompt; the model generates smooth motion, coherent visuals, and synchronized sound design (voice-like audio cues, ambience, and effects) to match the on-screen action.
It’s designed for teams who need fast, production-ready video generation via REST API, especially when you want the output to feel like a complete “scene” instead of silent B-roll.
Key Features
- Image-to-video generation from one reference image (
image_url) - Native audio generation with
generate_audiofor richer, immersive clips - Cinematic motion + realism: smooth camera movement and consistent scene continuity
- Duration control: generate 5s or 10s videos (
duration) - Prompt steering + cleanup:
promptandnegative_promptfor precision - CFG control:
cfg_scale(0–1) to balance prompt adherence vs. natural motion - Aspect ratios:
16:9,9:16,1:1(aspect_ratio) for web, social, and product - Pro mode: set
mode="pro"for polished outputs
Best Use Cases
- Product explainers & promos: animate packshots into lifestyle motion with ambience
- Cinematic social content: vertical 9:16 reels with camera moves and sound
- Storytelling shorts: consistent scene building from a keyframe image
- Brand mood films: landscapes, interiors, and stylized establishing shots
- App/landing page hero media: loopable 5–10s visuals with audio atmosphere
Prompt Tips and Output Quality
- Start with a clear scene + action + camera: “slow dolly-in”, “handheld”, “crane up”.
- Add lighting and mood: “golden hour”, “neon reflections”, “soft fog”.
- Use
negative_promptto prevent artifacts: “no distortion, no jitter, no clutter”. - Tune
cfg_scale:- Higher (~0.7–1.0): stronger style/detail adherence
- Lower (~0.3–0.6): more natural motion, fewer “over-directed” frames
- Pick
aspect_ratioearly (e.g., 16:9 cinematic, 9:16 social) to avoid reframing. - Enable
generate_audio=truewhen you want the scene to feel complete (ambience + SFX).
