Response Format

Initial Response

All 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 GET /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 is 2-6 minutes depending on duration and resolution.

Poll every 5-10 seconds to check status.

Best Practices

1. Describe Motion Clearly: Include specific movement descriptions in prompts
2. Resolution Selection: Use 480p for faster processing, 720p for higher quality
3. Reproducibility: Use the seed parameter to reproduce specific generations
4. Audio Enhancement: Keep sound enabled for more immersive video experiences
5. Image to Video: Provide a clear first frame via image_url; use image_end_url when you need controlled start and end frames
