Captions: word highlight, entrance and smart Auto

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.
