Generate videos from text prompts using the `/v1/videos/text2video` endpoint. Supports models v1 through v2.6, standard/professional modes, camera control, negative prompts, and native audio (v2.6+).

**Endpoint:** `POST https://api.klingai.com/v1/videos/text2video`

## Request Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `model_name` | string | Yes | Model version (see model catalog) |
| `prompt` | string | Yes | Video description, max 2500 chars |
| `negative_prompt` | string | No | What to exclude from generation |
| `duration` | string | Yes | `"5"` or `"10"` seconds |
| `aspect_ratio` | string | No | `"16:9"` (default), `"9:16"`, `"1:1"`, etc. |
| `mode` | string | No | `"standard"` (default) or `"professional"` |
| `cfg_scale` | float | No | Prompt adherence (0.0-1.0, default 0.5) |
| `camera_control` | object | No | Camera movement config |
| `callback_url` | string | No | Webhook URL for completion notification |

## Complete Example — Python

```python
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"}

# Create text-to-video task
response = requests.post(f"{BASE}/videos/text2video", headers=get_headers(), json={
    "model_name": "kling-v2-6",
    "prompt": "Aerial drone shot of a coral reef at golden hour, "
              "tropical fish swimming through crystal clear water, "
              "sun rays penetrating the surface, cinematic 4K",
    "negative_prompt": "blurry, low quality, distorted, watermark",
    "duration": "5",
    "aspect_ratio": "16:9",
    "mode": "professional",
    "cfg_scale": 0.5,
})

task = response.json()
task_id = task["data"]["task_id"]

# Poll for completion
while True:
    time.sleep(15)
    result = requests.get(
        f"{BASE}/videos/text2video/{task_id}", headers=get_headers()
    ).json()

    status = result["data"]["task_status"]
    if status == "succeed":
        video = result["data"]["task_result"]["videos"][0]
        print(f"Video URL: {video['url']}")
        print(f"Duration: {video['duration']}s")
        break
    elif status == "failed":
        raise RuntimeError(result["data"]["task_status_msg"])
    # else: submitted/processing — keep polling
```

## With Camera Control

```python
# Camera movement types: pan, tilt, zoom, roll
response = requests.post(f"{BASE}/videos/text2video", headers=get_headers(), json={
    "model_name": "kling-v2-6",
    "prompt": "A medieval castle on a cliff at sunrise, fog in the valley",
    "duration": "5",
    "mode": "standard",
    "camera_control": {
        "type": "simple",
        "config": {
            "horizontal": 5,    # pan right (negative = left), range -10 to 10
            "vertical": 0,      # tilt (negative = down, positive = up)
            "zoom": 3,          # zoom in (positive) or out (negative)
            "roll": 0,          # rotation
            "pan": 0,           # dolly left/right
            "tilt": -2,         # dolly up/down
        }
    },
})
```

**Rule:** Only one non-zero field in `config` for `type: "simple"`.

## With Native Audio (v2.6 only)

```python
response = requests.post(f"{BASE}/videos/text2video", headers=get_headers(), json={
    "model_name": "kling-v2-6",
    "prompt": "A jazz band performing in a dimly lit club, saxophone solo, "
              "audience clapping, warm amber lighting",
    "duration": "10",
    "mode": "professional",
    "motion_has_audio": True,  # generates synchronized audio
})
```

## Prompt Engineering Tips

| Technique | Example |
|-----------|---------|
| Scene + action + style | "A samurai walking through cherry blossoms, cinematic slow motion" |
| Lighting cues | "golden hour", "neon-lit", "overcast diffused light" |
| Camera language | "close-up", "wide establishing shot", "tracking shot" |
| Negative prompt | "blurry, watermark, text overlay, distorted faces" |
| Material/texture | "brushed steel", "hand-painted watercolor", "photorealistic" |

## Cost Reference

| Duration | Standard | Professional |
|----------|----------|-------------|
| 5 seconds | 10 credits | 35 credits |
| 10 seconds | 20 credits | 70 credits |

## Error Handling

| Error | Cause | Fix |
|-------|-------|-----|
| `400` invalid prompt | Empty or >2500 chars | Check prompt length |
| `400` invalid model | Unsupported `model_name` | Use valid model ID from catalog |
| `402` insufficient credits | Not enough credits | Top up account |
| `task_status: failed` | Content policy violation or complexity | Simplify prompt, remove restricted content |
