Kling AI Storage Integration

Overview

Kling AI video URLs from task_result.videos[].url are temporary CDN links that expire. You must download and store videos in your own storage. This skill covers S3, GCS, and Azure Blob.

Download from Kling CDN

import requests
import os

def download_video(video_url: str, output_dir: str = "output") -> str:
    """Download generated video from Kling CDN."""
    os.makedirs(output_dir, exist_ok=True)

    # Extract filename or generate one
    filename = video_url.split("/")[-1].split("?")[0]
    if not filename.endswith(".mp4"):
        filename = f"kling_{int(time.time())}.mp4"

    filepath = os.path.join(output_dir, filename)
    response = requests.get(video_url, stream=True, timeout=120)
    response.raise_for_status()

    with open(filepath, "wb") as f:
        for chunk in response.iter_content(chunk_size=8192):
            f.write(chunk)

    size_mb = os.path.getsize(filepath) / (1024 * 1024)
    print(f"Downloaded: {filepath} ({size_mb:.1f} MB)")
    return filepath

Upload to AWS S3

import boto3

def upload_to_s3(filepath: str, bucket: str, key_prefix: str = "kling-videos/") -> str:
    """Upload video to S3 and return public URL."""
    s3 = boto3.client("s3")
    filename = os.path.basename(filepath)
    s3_key = f"{key_prefix}{filename}"

    s3.upload_file(
        filepath, bucket, s3_key,
        ExtraArgs={"ContentType": "video/mp4", "CacheControl": "max-age=86400"}
    )

    url = f"https://{bucket}.s3.amazonaws.com/{s3_key}"
    print(f"Uploaded to S3: {url}")
    return url

# Generate signed URL for private buckets
def get_signed_url(bucket: str, key: str, expiry: int = 3600) -> str:
    s3 = boto3.client("s3")
    return s3.generate_presigned_url(
        "get_object",
        Params={"Bucket": bucket, "Key": key},
        ExpiresIn=expiry,
    )

Upload to Google Cloud Storage

from google.cloud import storage

def upload_to_gcs(filepath: str, bucket_name: str, prefix: str = "kling-videos/") -> str:
    """Upload video to GCS and return public URL."""
    client = storage.Client()
    bucket = client.bucket(bucket_name)
    filename = os.path.basename(filepath)
    blob = bucket.blob(f"{prefix}{filename}")

    blob.upload_from_filename(filepath, content_type="video/mp4")
    blob.make_public()  # or use signed URLs for private access

    print(f"Uploaded to GCS: {blob.public_url}")
    return blob.public_url

# Signed URL for private access
def get_gcs_signed_url(bucket_name: str, blob_name: str, expiry_min: int = 60) -> str:
    from datetime import timedelta
    client = storage.Client()
    bucket = client.bucket(bucket_name)
    blob = bucket.blob(blob_name)
    return blob.generate_signed_url(expiration=timedelta(minutes=expiry_min))

Upload to Azure Blob Storage

from azure.storage.blob import BlobServiceClient

def upload_to_azure(filepath: str, container: str,
                    connection_string: str = None) -> str:
    """Upload video to Azure Blob Storage."""
    conn_str = connection_string or os.environ["AZURE_STORAGE_CONNECTION_STRING"]
    client = BlobServiceClient.from_connection_string(conn_str)
    filename = os.path.basename(filepath)
    blob_client = client.get_blob_client(container=container, blob=f"kling-videos/{filename}")

    with open(filepath, "rb") as f:
        blob_client.upload_blob(f, content_type="video/mp4", overwrite=True)

    url = blob_client.url
    print(f"Uploaded to Azure: {url}")
    return url

End-to-End Pipeline

def generate_and_store(prompt: str, bucket: str, provider: str = "s3"):
    """Generate video with Kling AI and store in cloud."""
    # 1. Generate
    r = requests.post(f"{BASE}/videos/text2video", headers=get_headers(), json={
        "model_name": "kling-v2-master",
        "prompt": prompt,
        "duration": "5",
        "mode": "standard",
    }).json()
    task_id = r["data"]["task_id"]

    # 2. Poll
    result = poll_task("/videos/text2video", task_id)
    video_url = result["videos"][0]["url"]

    # 3. Download
    filepath = download_video(video_url)

    # 4. Upload
    if provider == "s3":
        return upload_to_s3(filepath, bucket)
    elif provider == "gcs":
        return upload_to_gcs(filepath, bucket)
    elif provider == "azure":
        return upload_to_azure(filepath, bucket)

    # 5. Cleanup temp file
    os.remove(filepath)

Metadata Preservation

import json

def save_with_metadata(filepath: str, task_id: str, prompt: str, model: str):
    """Save video metadata alongside the file."""
    meta = {
        "task_id": task_id,
        "prompt": prompt,
        "model": model,
        "generated_at": time.strftime("%Y-%m-%dT%H:%M:%SZ"),
        "filename": os.path.basename(filepath),
    }
    meta_path = filepath.replace(".mp4", ".meta.json")
    with open(meta_path, "w") as f:
        json.dump(meta, f, indent=2)
    return meta_path
