Popline caption style
Popline is a free animated caption style for captions.js: Raleway bold, the spoken word in #F43FE0, 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.

import captionsjs, { getPreset } from "captions.js";

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