# Use Video Edit Green Screen with Comfy Router

> Call bria/video-edit-green-screen through Comfy Router: endpoint, request shape and the response Router returns.

Use `bria/video-edit-green-screen` with the Comfy Router API. Bria provides the model; Router gives it the shared authentication and request route below.

## Quick start

Create a key at [platform.comfy.org/profile/api-keys](https://platform.comfy.org/profile/api-keys) and export it as `COMFY_API_KEY`. The Python and TypeScript snippets use the Comfy SDKs (`pip install comfy-sdk`, `npm install @comfyorg/sdk`); the cURL snippet is the same call over raw HTTP.

**Model ID:** `bria/video-edit-green-screen`

**Endpoint:** `POST https://api.comfy.org/v2/models/bria/video-edit-green-screen`

<CodeGroup>
  ```python Python theme={null}
  import uuid
  from comfy_sdk import Comfy

  # Reads COMFY_API_KEY from the environment. Store this UUID before starting a
  # generation. Use the same value if you retry it.
  idempotency_key = str(uuid.uuid4())
  with Comfy() as client:
      result = client.models.run(
          "bria/video-edit-green-screen",
          {
              "green_shade": "broadcast_green",
              "video": "https://example.com/input.mp4",
          },
          idempotency_key=idempotency_key,
          timeout=660.0,
      )

  print(result)
  ```

  ```typescript TypeScript theme={null}
  import { comfy } from "@comfyorg/sdk";

  // Reads COMFY_API_KEY from the environment. Store this UUID before starting a
  // generation. Use the same value if you retry it.
  const idempotencyKey = crypto.randomUUID();
  const { data } = await comfy.models.run("bria/video-edit-green-screen", {
    green_shade: "broadcast_green",
    video: "https://example.com/input.mp4",
  }, { idempotencyKey, timeoutMs: 660_000 });

  console.log(data);
  ```

  ```bash cURL theme={null}
  # Run this line once. Reuse ROUTER_REQUEST_KEY if you retry the curl command.
  ROUTER_REQUEST_KEY=$(uuidgen)
  curl --max-time 660 https://api.comfy.org/v2/models/bria/video-edit-green-screen \
    -H "X-API-Key: $COMFY_API_KEY" \
    -H "Idempotency-Key: $ROUTER_REQUEST_KEY" \
    -H "Content-Type: application/json" \
    -d "{\"green_shade\": \"broadcast_green\", \"video\": \"https://example.com/input.mp4\"}"
  ```

## Schema

### Input

<ParamField body="green_shade" type="string">
  The solid background shade applied behind the foreground for chroma keying. Defaults to broadcast\_green.

  Possible values: `broadcast_green`, `chroma_green`, `blue_screen`
</ParamField>

<ParamField body="output_container_and_codec" type="string">
  Output container and codec preset.

  Possible values: `mp4_h264`, `mp4_h265`, `webm_vp9`, `mov_h265`, `mov_proresks`, `mkv_h264`, `mkv_h265`, `mkv_vp9`, `gif`
</ParamField>

<ParamField body="preserve_audio" type="boolean">
  Whether to preserve audio from the input video.
</ParamField>

<ParamField body="video" type="string" required>
  Publicly accessible URL of the input video. Input resolution supported up to 16000x16000 (16K). Max duration 60 seconds.
</ParamField>

Generated from the schema Router serves at `GET /v2/models/bria/video-edit-green-screen/openapi.json`, the same document it validates a call against before the request reaches the provider.

### Output

Router does not publish an output schema for this model.

## Examples

### Input

```json theme={null}
{
  "green_shade": "broadcast_green",
  "video": "https://example.com/input.mp4"
}
```

## Before you ship

Save one `Idempotency-Key` for each call and reuse it for retries. Router can hold the connection for up to 10 minutes. The SDKs handle authentication; raw HTTP clients send the headers themselves.

When a request fails, Router sends an `X-Comfy-Error-Type` response header explaining why. A `422` means Router rejected the input before calling the provider. Download generated assets promptly because [result URLs can expire](/development/comfy-router/reference#result-assets).
