Kling AI Style Transfer & Effects

Overview

Apply artistic styles through prompt engineering, use the Effects API for pre-built visual transformations, and leverage Kolors for image-based style references. Available on v1.6+ models.

Style via Prompt Engineering

The most direct approach -- include style descriptors in your prompt:

import jwt, time, os, requests

BASE = "https://api.klingai.com/v1"

def get_headers(): ak, sk = os.environ["KLING_ACCESS_KEY"], os.environ["KLING_SECRET_KEY"] token = jwt.encode( {"iss": ak, "exp": int(time.time()) + 1800, "nbf": int(time.time()) - 5}, sk, algorithm="HS256", headers={"alg": "HS256", "typ": "JWT"} ) return {"Authorization": f"Bearer {token}", "Content-Type": "application/json"}

Style: Studio Ghibli watercolor

response = requests.post(f"{BASE}/videos/text2video", headers=get_headers(), json={ "model_name": "kling-v2-6", "prompt": "A cozy cottage in a meadow, hand-painted watercolor style, " "soft pastel colors, Studio Ghibli aesthetic, gentle breeze", "negative_prompt": "photorealistic, harsh lighting, dark, gritty", "duration": "5", "mode": "professional", "cfg_scale": 0.7, # higher = stricter prompt adherence })


## Style Prompt Recipes

| Style | Prompt Keywords | cfg_scale |
|-------|----------------|-----------|
| Cinematic | "cinematic lighting, anamorphic lens, film grain, 35mm" | 0.5-0.6 |
| Anime | "anime style, cel-shaded, vibrant colors, clean lines" | 0.6-0.7 |
| Watercolor | "watercolor painting, soft edges, pastel, hand-painted" | 0.7-0.8 |
| Oil painting | "oil painting, thick brushstrokes, impasto, canvas texture" | 0.7-0.8 |
| Neon/cyberpunk | "neon lights, cyberpunk, rain, dark city, purple and blue" | 0.5-0.6 |
| Vintage film | "vintage 8mm film, warm tones, light leaks, soft focus" | 0.6-0.7 |
| Pixel art | "pixel art style, retro 16-bit, limited palette" | 0.8-0.9 |
| Photorealistic | "photorealistic, 4K, natural lighting, DSLR quality" | 0.4-0.5 |

## Effects API

The Effects API applies pre-built transformations to existing images. Available on v1.6+.

**Endpoint:** `POST https://api.klingai.com/v1/videos/effects`

```python
# Apply an effect to an image
response = requests.post(f"{BASE}/videos/effects", headers=get_headers(), json={
    "model_name": "kling-v1-6",
    "image": "https://example.com/portrait.jpg",
    "effect_type": "hug",           # effect to apply
    "duration": "5",
    "mode": "standard",
})

task_id = response.json()["data"]["task_id"]
# Poll for result as usual

Available Effects

Effect	Description
`hug`	Embrace/hug motion between subjects
`kiss`	Kiss animation between subjects
`heart`	Heart gesture or heart-shaped framing
`expand`	Zoom/expand outward effect
`squish`	Compression/squish animation

Kolors Image Restyle

Use Kolors to restyle images before converting to video:

# Generate styled image with Kolors
image_response = requests.post(f"{BASE}/images/kolors", headers=get_headers(), json={
    "prompt": "A cyberpunk city street, neon signs, rain-slicked roads",
    "aspect_ratio": "16:9",
    "imageCount": 1,
})

# Then use the generated image as input for I2V
image_url = image_response.json()["data"]["images"][0]["url"]
video_response = requests.post(f"{BASE}/videos/image2video", headers=get_headers(), json={
    "model_name": "kling-v2-1",
    "image": image_url,
    "prompt": "Camera slowly pushes forward through the rain, neon reflections",
    "duration": "5",
    "mode": "professional",
})

cfg_scale Tuning

The cfg_scale parameter (0.0-1.0) controls how strictly the model follows your prompt:

cfg_scale	Effect
0.0-0.3	More creative freedom, may drift from prompt
0.4-0.5	Balanced (default), natural results
0.6-0.7	Stronger prompt adherence
0.8-1.0	Very strict, may reduce quality/naturalness

For style transfer: Use 0.6-0.8 to ensure the style keywords are respected.

Style Consistency Across Clips

# Use a consistent style template for all clips in a project
STYLE_TEMPLATE = {
    "suffix": ", cinematic lighting, 35mm film grain, warm color grading, "
              "anamorphic lens flare, shallow depth of field",
    "negative": "cartoon, anime, painting, illustration, CGI, digital art",
    "cfg_scale": 0.6,
    "model": "kling-v2-6",
    "mode": "professional",
}

def styled_generation(scene_prompt: str):
    return requests.post(f"{BASE}/videos/text2video", headers=get_headers(), json={
        "model_name": STYLE_TEMPLATE["model"],
        "prompt": scene_prompt + STYLE_TEMPLATE["suffix"],
        "negative_prompt": STYLE_TEMPLATE["negative"],
        "cfg_scale": STYLE_TEMPLATE["cfg_scale"],
        "duration": "5",
        "mode": STYLE_TEMPLATE["mode"],
    })

Prerequisites

An approved style brief, rights-cleared or synthetic references, sandbox workspace, content-policy review, credit cap, draft-only destination, and an asset-removal owner.

Instructions

Use only approved style references and a watermarked sandbox canary; reject living-artist imitation requests, private materials, and unlicensed inputs unless documented rights permit them.
Verify reference rights, policy outcome, model/mode, duration, credit estimate, and draft destination before submission.
Review the canary for attribution, policy, and quality; cancel and remove it on rights, policy, or budget drift rather than publishing it.
Promote only after owner approval and retain a redacted receipt with removal at the approved retention boundary.

Output

Produce a style-transfer receipt with style-brief ID, reference classification, model/mode, credit estimate, policy/rights outcome, draft-only status, approver, and cleanup reference. Exclude prompt text, asset URLs, identities, and credentials.

Error Handling

Condition	Response
Reference rights or imitation policy is unclear	Do not generate; request documented clearance or use a synthetic, non-identifying alternative.
Policy or budget check fails	Cancel the task, remove temporary drafts, and require owner review before retrying.

Examples

style=approved-geometric-motion; references=synthetic; mode=standard; policy=pass; rights=pass; destination=draft-only; cleanup=24h is safe to review.
