    - `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)

    - `preset` 'none' | 'warm' | 'cool' | 'vivid' | 'cinematic' | 'teal-orange' | 'bw' | 'vintage' | 'matte': A ready grade; the fields below fine-tune it

    - `temperature` number: −1 cool (blue) … +1 warm (orange)
  - `fonts` object[]: Your brand fonts: up to 4 fonts from your brand kit, each { family, url } (the url as the brand kit gives it — your own files only). A caption, hook or text style may then name `family` as its `font`. Text a font cannot draw (Hebrew words in a Latin-only font) is set in the nearest built-in font, and the render's `warnings` say so

    - `start_ms` number: Start the music this far into the video
    - `normalize` boolean: Bring the track to a standard loudness first, so `volume` means the same for every file (a quiet file is not lost under the speech)
    - `fade_in_ms` number
    - `fade_out_ms` number

  - `words` object[]: Your own timed words (ms) instead of a transcript

  - `effects` object[]: Effects from the library — GET /v1/effects: [{ id, params, start + duration | at | during }]. Each one is applied by its pipeline stage (never by array order) and renders in this same call
    - `at` object: Start at a word (instead of a time)
      - `edge` 'start' | 'end', required: The moment the word starts, or the moment it ends
      - `word` string, required: The word's id (w0001…)

  - `inserts` object[]: Clips placed INTO the video in the same render — b-roll, a stock clip, an excerpt of a video you may use — each from its own in-point (`from`), at a time or on words: `cut` replaces the picture (and with `audio: "keep"` the sound), `overlay` lays it full frame over the video, `pip` in a box. Unlike `overlays` an insert brings its sound and starts where you say inside the clip
    - `x` number: pip: exact placement, % of the width (the box's centre)
    - `y` number: pip: exact placement, % of the height

    - `id` string: Your name for the element; the render report uses it
    - `fit` 'crop' | 'blur' | 'pad': cut / overlay: how a clip of another shape fills the frame — crop the edges (default), a blurred copy behind it, or bars
    - `url` string, uri, required: The clip (mp4, mov, webm…): b-roll, a stock clip, an excerpt of a video you are allowed to use (your own, CC BY with its credit line on screen as a `texts[]` element, licensed) — e.g. the url of POST /v1/youtube/videos/{id}/file. Its licence is the record its own call kept (the file call, an upload's `license`, a stock save) — GET /v1/usage?tag=<job> lists the job's sources
    - `from` number: Where inside the clip to start, seconds — the in-point of an excerpt
    - `mode` 'cut' | 'overlay' | 'pip': cut = the clip replaces the picture for its span (a cut-away; with `audio: "keep"` it replaces the sound too) · overlay = full frame over the video, dissolving in and out, the video's sound carries on · pip = in a box (`position` / `x`,`y`, `size`), the video's sound carries on
    - `size` number: pip: the box's width, % of the video's width (the clip's shape is kept)
    - `audio` 'keep' | 'duck' | 'mute': The clip's OWN sound. keep = heard at `volume` — in `cut` mode instead of the video's sound (the captions of the words it covers are left out: nobody hears them), otherwise mixed over it · duck = heard under the speech, dipping `duck_db` whenever the speaker talks · mute = silent (b-roll; the default)
    - `start` number: seconds, on the edited (output) timeline — or anchor it with `at` (a word) / `during` (a stretch of words)
    - `during` object: Start and end with a stretch of words (instead of a time and a duration)
      - `to` string, required: Id of the last word

      - `pad_end_ms` number: End this much later (default 0)
      - `pad_start_ms` number: Start this much earlier (default 0)
    - `volume` number: The clip's sound level (1 = as recorded)
    - `duck_db` number: audio duck: how far the clip's sound dips while the speaker talks, dB
    - `duration` number: Seconds on screen. Default: the rest of the clip from `from` (a `during` span sets it instead). Never runs past the clip or the video — a longer ask is shortened and reported in `warnings`
    - `position` 'top-left' | 'top-right' | 'bottom-left' | 'bottom-right' | 'center': pip: the corner
    - `transition` object: Default: a hard cut for `cut`, a 240 ms crossfade for `overlay` and `pip`
      - `ms` number: Length of the transition, ms (at most a third of the clip on screen)
      - `type` 'cut' | 'crossfade' | 'dip', required: cut = a hard cut in and out · crossfade = the clip dissolves in over its first `ms` and out over its last (picture and sound) · dip = through black: the video fades down over the `ms / 2` before the clip, the clip up over its first `ms / 2` (and the same on the way out)
  - `brand_id` string: A brand of yours (GET /v1/brands): its logo (at its corner), colours, fonts and caption style fill what this request leaves out — anything you set here wins. `default` = your default brand
  - `captions` object
    - `style` union: A preset id (GET /v1/studio/caption-styles) or a style object; `preset` + fields overrides a preset. A retired preset still works: it renders as the default with a warning
