Try out this capability in Bria's sandbox

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 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.
