Response Format

Initial Response

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

Best Practices

1. Resolution: Use 720p or 1080p for a balance of quality and generation time; use 360p or 540p for faster iteration.
2. Transitions: Use sharp, well-lit first and last frames so the model can interpolate motion reliably.
3. Audio: Set sound when you want synchronized ambient audio; omit or set false for silent output.
4. Polling: Poll every 5–10 seconds until task_status is succeed or failed.
