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

Quick start

Create a key at 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-replace-background Endpoint: POST https://api.comfy.org/v2/models/bria/video-edit-replace-background

Schema

Input

string
required
Publicly accessible URL of the background asset (image or video) to composite behind the foreground. Must match the foreground aspect ratio.
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
boolean
Whether to preserve audio from the input (foreground) video.
string
required
Publicly accessible URL of the input (foreground) video. Input resolution supported up to 16000x16000 (16K). Max duration 60 seconds.
Generated from the schema Router serves at GET /v2/models/bria/video-edit-replace-background/openapi.json, the same document it validates a call against before the request reaches the provider.

Output

Input

Before you ship

The snippets above are the shortest working call. Three things are the same for every model and are documented once on the Comfy Router headers page: send an Idempotency-Key on every paid call and reuse it when you retry, expect the connection to be held up to Router’s 10 minute deadline, and keep X-Comfy-Request-Id from every response. The SDKs do all three for you; the cURL tab does none of them. On failure, X-Comfy-Error-Type names the bucket, and a 422 means the body failed the model’s schema and was never billed.

Headers

Authentication, idempotency, request IDs, error buckets, retry pacing, spend limits.

Quick Start

Typed error handling in Python and TypeScript, reading the 422, walking the catalog.

Limitations

What Router does not do today, and what to use instead.
