  title: Video API Reference Masking Endpoints API
  version: ''
  description: "Bria's Video APIs empower builders with powerful tools for programmatically transforming video content while maintaining original quality.\n\nThe Video API is organized into two transport paradigms:\n\n- **REST API (Async)** — Standard HTTP request/response. You submit a job, receive a `request_id` and `status_url`, and poll the [Status Service](https://docs.bria.ai/status) until the job completes. Use this for editing, masking, and most batch-style workflows.\n- **Streaming API (WebSocket)** — Persistent bidirectional connection for low-latency, frame-by-frame processing. Use this when you need real-time output (e.g., live video feeds, interactive previews).\n\n**Asynchronous Requests and the Status Service**  \nBria API v2 REST endpoints process requests asynchronously by default. When you make an asynchronous request, the API immediately returns a `request_id` and a `status_url` instead of the final result. Use the Status Service to track the request's progress until it reaches a completed state.\n\nSee the full guide at [Status Service Documentation](https://docs.bria.ai/status) for complete details and usage examples.\n"
