Karaoke captions
Social captions on the voice: a line or two at a time, the word being said lit by a pill that slides from word to word (or in the accent colour, or underlined), the rest of the line waiting dimmed. Give a transcript with --words; *starred* words and the ones in `accents` take the accent.

npx volito render captions/karaoke --words talk.json --out karaoke.movCaptions take their timing from a transcript: --words reads Whisper JSON or [{w, s, e}], one entry a word. Add text to caption your own wording on the voice's timing; without a transcript, text runs at pace seconds a word. Starred words and the ones listed in accents are the key words.

Camera-follow captions
Each sentence written across a canvas far bigger than the frame while a camera follows the words as they are said: every word a step bigger than the last with the camera pulling back to keep it the same size (or the camera gliding along lines of text), motion blur on every move, and a pull-back at the sentence's end to show it whole. Give a transcript with --words; *starred* words and the ones in `accents` take the accent.
Pop captions
Big captions a few words at a time, each word landing on its own time with a pop — the newest one in the accent. Give a transcript with --words; *starred* words and the ones in `accents` take the second accent.
Subtitles
Clean subtitles timed to the voice: up to two lines at a time in the brand's text face, broken at pauses and sentence ends, on a dark box behind each line or with a shadow. Give a transcript with --words.
Marker captions
A highlighter swipes under each word as it is said and stays lit, a little crooked like a real pen, so the line fills with the brand's colour as it is spoken (or an underline stroke). Give a transcript with --words; *starred* words take the second accent.
Neon captions
The line hangs as unlit glass tubes and each word flickers on as it is said, glowing in the accent (accent words in the second accent) and drifting a hair once lit. Give a transcript with --words.
Decode captions
Each word arrives as scrambled characters that settle into the word letter by letter as it is said, in the mono face (or the display face). Give a transcript with --words.
