# Use Video Edit V1 with Comfy Router

> Call bfl/video-edit-v1 through Comfy Router: endpoint, request shape and the response Router returns.

API Reference for `bfl/video-edit-v1`, served by Comfy Router from Black Forest Labs.

## Quick start

Create a key in [your Comfy workspace](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:** `bfl/video-edit-v1`

**Endpoint:** `POST https://api.comfy.org/v2/models/bfl/video-edit-v1`

<CodeGroup>
  ```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(
          "bfl/video-edit-v1",
          {
              "prompt": "Remove the orange bucket.",
              "video": "https://example.com/clip.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("bfl/video-edit-v1", {
    prompt: "Remove the orange bucket.",
    video: "https://example.com/clip.mp4",
  });

  console.log(data);
  ```

  ```bash cURL theme={null}
  curl https://api.comfy.org/v2/models/bfl/video-edit-v1 \
    -H "X-API-Key: $COMFY_API_KEY" \
    -H "Idempotency-Key: $(uuidgen)" \
    -H "Content-Type: application/json" \
    -d "{\"prompt\": \"Remove the orange bucket.\", \"video\": \"https://example.com/clip.mp4\"}"
  ```

## Schema

### Input

<ParamField body="prompt" type="string" required>
  Edit instruction. Names the objects, setting, style, on-screen text or dialogue to change; everything not named is preserved.
</ParamField>

<ParamField body="safety_tolerance" type="integer" default="2">
  Tolerance level for input and output moderation, 0 being most strict.

  Range: `0` to `4`
</ParamField>

<ParamField body="video" type="string" required>
  Video to edit, either an HTTP(S) URL or a base64-encoded MP4. At most 15 seconds of source footage and 50 MiB, with each side at least 160 pixels; sources above 720p are downscaled to 720p.
</ParamField>

Generated from the schema Router serves at `GET /v2/models/bfl/video-edit-v1/openapi.json`, the same document it validates a call against before the request reaches the provider.

### Output

<ResponseField name="cost" type="number">
  Provider-reported cost in credits, populated once the task is Ready.

  Format: `float`
</ResponseField>

<ResponseField name="id" type="string" required>
  BFL task identifier.
</ResponseField>

<ResponseField name="progress" type="number">
  Optional generation progress reported by BFL.

  Range: `0` to `1`

  Format: `float`
</ResponseField>

<ResponseField name="result" type="object" required>
  The finished generation. Not nullable here: this component's `required` entry is a promise that a `200` carries the result, and a nullable `result` would reduce it to a key-presence check.
</ResponseField>

<ResponseField name="result.cost" type="number">
  Provider-reported cost of the generation. This is BFL's number, not the Comfy charge.

  Format: `double`
</ResponseField>

<ResponseField name="result.duration" type="number">
  Provider-reported generation duration in seconds.

  Format: `double`
</ResponseField>

<ResponseField name="result.end_time" type="number">
  Provider-reported completion time of the generation, in seconds since the Unix epoch. `double` for the same reason as `start_time`.

  Format: `double`
</ResponseField>

<ResponseField name="result.prompt" type="string">
  The prompt the generation actually ran, after any prompt upsampling.
</ResponseField>

<ResponseField name="result.sample" type="string (uri)">
  Signed URL for the generated asset. Router re-hosts the asset onto Comfy storage and rewrites this field, so it is normally a Comfy-hosted URL valid for up to 24 hours - signed for 24 hours when minted, and replayed from a 23-hour memo, so a later poll can hand back one with as little as an hour left; a leaf whose re-host could not be performed keeps BFL's own short-lived delivery URL instead - roughly two hours for video, roughly ten minutes for images. Either way the link expires, so download the asset rather than storing the URL.

  Format: `uri`
</ResponseField>

<ResponseField name="result.seed" type="integer">
  The seed the generation used, whether supplied or chosen by the provider. Declared `int64` because BFL returns seeds above 2^31 (e.g. 2784347701), which an unformatted `integer` generates as a 32-bit field in many SDK generators.

  Format: `int64`
</ResponseField>

<ResponseField name="result.start_time" type="number">
  Provider-reported start time of the generation, in seconds since the Unix epoch. `double`, not `float`: float32 spacing near a present-day epoch value is \~128 seconds, which collapses a whole generation's span to a single decoded value.

  Format: `double`
</ResponseField>

<ResponseField name="status" type="string" required>
  Task status: Pending, Reasoning, Generating, Ready, Request Moderated, Content Moderated, Error, or Task not found.
</ResponseField>

## Examples

### Input

```json theme={null}
{
  "prompt": "Remove the orange bucket.",
  "video": "https://example.com/clip.mp4"
}
```

### Output

```json theme={null}
{
  "cost": null,
  "id": "b2e0c1a4-0f2f-4a55-9f2e-2f9a1c0d4e77",
  "progress": null,
  "result": {
    "cost": null,
    "duration": 3.4,
    "end_time": 1767225603.4,
    "prompt": "A watercolor painting of a lighthouse at dawn, soft light on the water",
    "sample": "https://example.invalid/bfl/flux-pro-1.1/sample.png",
    "seed": 2784347701,
    "start_time": 1767225600
  },
  "status": "Ready"
}
```

## 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. Download generated assets promptly because [result URLs can expire](/development/comfy-router/reference#result-assets).
