Rendered by the captions.js engine, not a mock-up.
Sky caption style
Sky is a free animated caption style for captions.js: Montserrat black in uppercase, the spoken word in #FFFFFF, with the "slide-left" word animation at the bottom of the frame. Use it live in the browser or burn it into an MP4 with FFmpeg.
Use it
import captionsjs, { getPreset } from "captions.js";
captionsjs({
video: document.querySelector("video")!,
captions, // word timings: see the Whisper and Deepgram guides
preset: getPreset("Sky"),
});npx captions.js burn video.mp4 words.json --preset "Sky"No servers? Render it through the captions.js Cloud API (early access).

Make it yours
A preset is a plain object. Clone it and change colors, font or animation; the browser and the FFmpeg render both take the result.
const base = getPreset("Sky");
const mine = {
...base,
captionsSettings: {
...base.captionsSettings,
style: { ...base.captionsSettings.style, highlightColor: "#ff2e88" },
},
};
