Rendered by the captions.js engine, not a mock-up.
Classic caption style
Classic is a free animated caption style for captions.js: Roboto bold, the spoken word in #ffffff, with the "none" 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("Classic"),
});npx captions.js burn video.mp4 words.json --preset "Classic"No servers? Render it through the captions.js Cloud API (early access).
import { burnCaptions } from "@captionsjs/server";
await burnCaptions({ video: "video.mp4", captions: "words.json", preset: "Classic" });Style details

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("Classic");
const mine = {
...base,
captionsSettings: {
...base.captionsSettings,
style: { ...base.captionsSettings.style, highlightColor: "#ff2e88" },
},
};
