# Use Video Edit Erase with Comfy Router

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

API Reference for `bria/video-edit-erase`, served by Comfy Router from Bria.

**Input:** Video · **Output:** Video

## Quick start

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

**Model ID:** `bria/video-edit-erase`

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

**Wait for the result**

```python Python theme={null}
from comfy_sdk import Comfy

# Reads COMFY_API_KEY from the environment.
# The SDK automatically creates an idempotency key and reuses it for automatic retries.
with Comfy() as client:
    result = client.models.run(
        "bria/video-edit-erase",
        {
            "auto_trim": True,
            "mask": "https://bria-test-images.s3.us-east-1.amazonaws.com/videos/eraser/video1_mask.mp4",
            "video": "https://bria-test-images.s3.us-east-1.amazonaws.com/videos/eraser/video1_video.mp4",
        },
    )

print(result)
```

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

// Reads COMFY_API_KEY from the environment.
// The SDK automatically creates an idempotency key and reuses it for automatic retries.
const { data } = await comfy.models.run("bria/video-edit-erase", {
  auto_trim: true,
  mask: "https://bria-test-images.s3.us-east-1.amazonaws.com/videos/eraser/video1_mask.mp4",
  video: "https://bria-test-images.s3.us-east-1.amazonaws.com/videos/eraser/video1_video.mp4",
});

console.log(data);
```

```bash cURL theme={null}
curl https://api.comfy.org/v2/models/bria/video-edit-erase \
  -H "X-API-Key: $COMFY_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d "{\"auto_trim\": true, \"mask\": \"https://bria-test-images.s3.us-east-1.amazonaws.com/videos/eraser/video1_mask.mp4\", \"video\": \"https://bria-test-images.s3.us-east-1.amazonaws.com/videos/eraser/video1_video.mp4\"}"
```

**Queue and collect later**

The same body, sent to `POST https://api.comfy.org/v2/models/bria/video-edit-erase/requests`. Router answers `201` with a `request_id` as soon as the run is admitted, and the result is collected once it is ready, from this process or another one. [Queued delivery](https://docs.comfy.org/development/comfy-router/queue.md) walks through status, cancellation and collection.

```python Python theme={null}
import asyncio
from comfy_sdk import AsyncComfy

# Reads COMFY_API_KEY from the environment.
# Each submit() call mints its own Idempotency-Key and reuses it for automatic retries.
async def main():
    async with AsyncComfy() as client:
        handle = await client.models.submit(
            "bria/video-edit-erase",
            {
                "auto_trim": True,
                "mask": "https://bria-test-images.s3.us-east-1.amazonaws.com/videos/eraser/video1_mask.mp4",
                "video": "https://bria-test-images.s3.us-east-1.amazonaws.com/videos/eraser/video1_video.mp4",
            },
        )
        print("request_id:", handle.request_id)  # with the model ID, all another process needs

        # Poll until the request completes, waiting the Retry-After the server names.
        async for update in handle.iter_events():
            print(update.status, update.queue_position)

        # The provider's own payload, the same value models.run() returns.
        # A request that failed or was cancelled raises the typed Router error here.
        result = await handle.get()

    print(result)

asyncio.run(main())
```

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

// Reads COMFY_API_KEY from the environment.
// Each submit() call mints its own Idempotency-Key and reuses it for automatic retries.
const handle = await comfy.models.submit("bria/video-edit-erase", {
  auto_trim: true,

});
console.log("requestId:", handle.requestId); // with the model ID, all another process needs

// Poll until the request completes, waiting the Retry-After the server names.
for await (const update of handle.events()) {
  console.log(update.status, update.queuePosition);
}

// The same result models.run() returns. A request that failed or was cancelled rejects here.
const result = await handle.get();

console.log(result.data);

## Schema

### Input

**auto\_trim** `boolean`

When true, videos longer than 5 seconds are trimmed to the first 5 seconds. When false (default), longer videos are rejected.

**mask** `string` *required*

Publicly accessible URL of a mask video that defines the area to erase. White pixels mark the region to remove, black pixels are preserved.

**output\_container\_and\_codec** `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`

**preserve\_audio** `boolean`

Whether to preserve audio from the input video.

**video** `string` *required*

Publicly accessible URL of the input video. Maximum duration 5 seconds unless auto\_trim is true. Input resolution supported up to 750p; larger inputs are downscaled.

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

### Output

**error** `object`

Error object (only present when status is ERROR)

**error.code** `integer`

Error code.

**error.details** `string`

Additional error details.

**error.message** `string`

Error message.

**request\_id** `string`

Unique identifier for the request.

**result** `object`

Result object (only present when status is COMPLETED)

**result.image\_url** `string`

URL of the generated/edited image.

**result.prompt** `string`

Original prompt.

**result.refined\_prompt** `string`

Refined version of the prompt, or null on a COMPLETED generation Bria did not refine. Nullable because the key is PRESENT carrying null rather than omitted; observed live on bria/image-edit-gen-fill.

**result.seed** `integer`

Seed used for generation.

**result.structured\_instruction** `string`

The structured instruction, a JSON document serialized as a string, that `/v2/structured_instruction/generate` returns. That operation fills neither URL.

**result.structured\_prompt** `string`

The detailed JSON structured prompt.

**result.video\_url** `string`

URL of the generated video.

**status** `string`

Current status of the request.

Possible values: `IN_PROGRESS`, `COMPLETED`, `ERROR`, `UNKNOWN`

}
```

## Before you ship

The SDKs create an `Idempotency-Key` and reuse it for automatic retries. For manual retries, reuse the original key. Router can hold the connection for up to 10 minutes.

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, and a `413` means the request body was larger than Router accepts. Download generated assets promptly because [result URLs can expire](https://docs.comfy.org/development/comfy-router/reference.md#result-assets).

Any size limit named in a field description above is the provider's own bound on that field, quoted from the provider's specification. Router applies a separate cap to the whole request body, which base64-encoded media counts against: see [request body size](https://docs.comfy.org/development/comfy-router/limitations.md#request-bodies-are-capped).

This page documents one partner model called through Comfy Router. The same `comfy-sdk` / `@comfyorg/sdk` package also ships a second client, for running a whole ComfyUI workflow graph on Comfy Cloud: `Comfy(api_key=...)` / `new Comfy({ apiKey })`, with `client.workflows`, `client.assets` and `client.jobs`. See [Comfy SDKs](https://docs.comfy.org/development/api-development/sdks.md).
