Video generation typically takes longer than image generation. Be prepared for longer processing times depending on video length and quality settings.

​
Step 1: Generate a Video

Make a POST request to /generate/video/kling/kling-2.5 with your prompt and video parameters. The API returns a job ID immediately. 
curl -X POST https://api.krea.ai/generate/video/kling/kling-2.5 \
  -H "Authorization: Bearer YOUR_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "a majestic eagle soaring over snow-capped mountains at sunrise",
    "duration": 5,
    "width": 1280,
    "height": 720,
    "fps": 24
  }'
Replace with your API TokenTo replace the YOUR_API_TOKEN placeholder in the above examples, you’ll need to generate an API token in krea.ai/settings/api-tokens. Follow the instructions on the API Keys & Billing page if you need help.
Example Response 
{
  "job_id": "550e8400-e29b-41d4-a716-446655440000",
  "status": "queued",
  "created_at": "2025-01-15T10:30:00.000Z",
  "estimated_time": "60-120 seconds"
}

​
Step 2: Poll for Results

Video generation takes longer than image generation. Poll /jobs/{job_id} every 5 seconds to check progress.

Prompt Tips for Better Videos:
  • Be specific about motion and camera movement
  • Describe the scene, lighting, and atmosphere
  • Mention timing (e.g., “slowly panning”, “quick zoom”)
  • Include style references (e.g., “cinematic”, “documentary style”)
Video generation consumes more compute units than image generation. Check your API Keys & Billing to monitor consumption.
