## Request body

- object
  - `format` 'mp4' | 'mov' | 'webm' | 'mp3' | 'wav' | 'm4a': The container to write (default: the file's own; another container gets mp4 for video, m4a for audio). The picture is copied as it is
  - `denoise` 'off' | 'auto' | 'light' | 'strong': Background-noise reduction (DeepFilterNet 3) — default `off` on edit / short / remove-silence, `auto` on clean-audio: `auto` measures the noise and reduces it only when there is some (a clean recording, a music bed or digital silence stays as it is) · `light` a gentle fixed reduction · `strong` as much as the model removes · `off` the sound as recorded. Mains hum (50/60 Hz) is notched out whenever it is found
  - `enhance` boolean: Gentle voice enhancement after the noise: a high-pass at 75 Hz, a de-esser, a 3:1 compressor and a small presence lift — each only when the measurement calls for it (a clean studio voice stays as it is)
  - `normalize` boolean: Set the cleaned sound to −16 LUFS, the social-media standard, with peaks under −1 dBTP
  - `video_url` string, uri, required: Public URL of the video or audio file (mp4, mov, webm, mp3, wav, m4a, ogg…) — or the `url` of a previous render

## Response `200`
