# Green Screen

`POST /green_screen`

[**Try out this capability in Bria's sandbox**](https://platform.bria.ai/video-editing/video-green-screen)


**Description**
Initiates an asynchronous job that detects the video background and replaces it with a solid green (or blue) screen, producing a chroma-key-ready output for downstream compositing tools.


Response behavior:

- Returns HTTP 202 with `request_id` and `status_url`

- Check job status by polling `status_url` or by calling the [Status Service](https://docs.bria.ai/status/endpoints/get_status) with the `request_id` until a terminal status is returned


Supported input containers:

- .mp4, .mov, .webm, .avi, .gif


Supported input codecs:

- H.264, H.265 (HEVC), VP9, AV1, PhotoJPEG


Input attributes preserved in output:

- Aspect Ratio and resolution

- Frame Rate

- Audio if present and `preserve_audio` is true


Limits:

- Max input duration: 60 seconds

- Resolutions: Input resolution up to 16000x16000 (16K). Inputs larger than this return 413 Payload Too Large. Output resolution matches the input resolution.


Green shade selection:

- `broadcast_green` (#00B140) - industry standard for professional pipelines. Default.

- `chroma_green` (#00FF00) - works with consumer editors.

- `blue_screen` (#0000FF) - use when the subject wears green.


Output transparency:

- Output is fully opaque (no alpha channel needed). `mp4_h264` is recommended for broad editor compatibility.

## Headers

- `api_token` string, required

## Request body

- object
  - `video` string, required — Publicly accessible URL of the input video. Input resolution supported up to 16000x16000 (16K)
  - `green_shade` 'broadcast_green' | 'chroma_green' | 'blue_screen' — Predefined screen color. `broadcast_green` (#00B140) is the industry standard for professional pipelines. `chroma_green` (#00FF00) works with consumer editors. `blue_screen` (#0000FF) is used when the subject wears green.
  - `output_container_and_codec` 'mp4_h264' | 'mp4_h265' | 'webm_vp9' | 'mov_h265' | 'mov_proresks' | 'mkv_h264' | 'mkv_h265' | 'mkv_vp9' | 'gif' — Output container and codec preset. Alpha is not needed for green screen output; `mp4_h264` is recommended for broad editor compatibility.
  - `preserve_audio` boolean
  - `webhook_url` string, uri — Optional URL for receiving the result via webhook when the async job completes. See [Webhooks](https://docs.bria.ai/webhooks).
