Response Format

Initial Response

Both models return a task_id for polling:

jsonCopy
{
  "code": 0,
  "message": "success",
  "data": {
    "task_id": "{task_id}",
    "response_url": "https://api.flaq.ai/api/v1/video/{task_id}",
    "task_status": "submitted"
  }
}

Polling Response

Poll /api/v1/video/{taskId} to check status:

jsonCopy
{
  "code": 0,
  "message": "success",
  "data": {
    "task_id": "{task_id}",
    "response_url": "https://api.flaq.ai/api/v1/video/{task_id}",
    "task_status": "succeed",
    "task_status_msg": null,
    "task_result": {
      "videos": [
        {
          "url": "https://example.com/generated-video.mp4"
        }
      ]
    }
  }
}

Status Values

• submitted: Task accepted and waiting to be processed
• processing: Video generation in progress
• succeed: Video generation completed
• failed: Video generation failed

Processing Time

Typical processing time: 2-5 minutes depending on duration and resolution settings.

Longer videos (10-15 seconds) may take up to 8 minutes.

Best Practices

1. Describe Scene & Motion: Include both scene content and camera movement in prompts
2. Resolution Selection: Use 720p for faster processing, 1080p for highest quality
3. Duration Planning: Longer videos cost more (per-second pricing)
4. Audio Integration: Can add custom audio via audio_url parameter
5. Image Quality: For image-to-video, use high-quality input images for best results
