# Captions: word highlight, entrance and smart Auto

> New Pop, Box and One word designs, the Pop template, the spoken-word highlight and phrase entrance, and Auto places each phrase where the frame is free.

Captions got livelier: the spoken word can pop, sit on a box or get an underline, a phrase can appear word by word, and with the **Auto** position each phrase finds free space in the frame by itself.

## New designs

-   ****Pop**** — 2–3 words on screen: the spoken word pops out in the accent color while the others make room.
-   ****Box**** — a line of up to six words: the spoken word sits on an accent box that slides from word to word.
-   ****One word**** — one big word at a time, in sync with speech.

The **Pop** template on the wizard's “Style” step pairs “Pop” with the Punch font and the **Lime** accent — for energetic videos.

## Caption options

The **Caption style** sheet, the project's **Settings** section and the wizard's **Captions** step have four new options that work with any design:

-   **Word highlight** — **Color**, **Pop**, **Box** or **Underline**: for example, in “Karaoke” the spoken word can now grow;
-   **Entrance** — **Fade**, **Pop**, **Slide up** or **Word by word**;
-   **Words on screen** — **One**, **2–3 words**, **Line** or **Phrase**;
-   **Letter case** — **CAPITALS** or **As spoken**.

All of them default to **As in the style**. Picking a design resets the highlight, entrance and words on screen to it, so a new design shows up the way it is meant to. Templates keep the new options too, and the director in the Chat changes them on request: “Make the spoken word pop”.

## Smart Auto

With the **Auto** position, each phrase goes where the frame has the most free space: off the face, the hook, plaques, titles and picture-in-picture windows. A phrase right after another keeps its place, and captions return to their usual place on a cut — the text doesn't jump without a reason. Emoji and media cards go next to the captions, wherever they are at that moment. Slicer knows where faces are after an AI montage or **Follow the face**, and Auto always steers clear of the reel's elements.

## Public API 1.8.0 and MCP

-   `subtitles` in the style (`PATCH /v1/projects/{id}/style`, the MCP tool `set_style`) and in montage settings has the fields `highlight`, `animation`, `words`, `letterCase` and `speakerColors`, and the designs `pop`, `box` and `word`; the `pop` template.
-   The `GET /v1/styles` catalog has `subtitleOptions`: the caption options with names and values in both languages.
-   A partial `subtitles` change now keeps the other fields — only what you pass in the request changes. A new `design` without `highlight`, `animation` and `words` resets them to `auto`.

Clients don't need to change anything — all changes are within `/v1`.
