Captions

Use captions when someone is speaking and the words need to be on screen — talking-head clips, voiceover demos, anything watched muted on a feed. These components take a timed transcript and render frame-accurate, burned-in subtitles inside per-aspect safe areas. For decorative headlines and titles, use Text & Titles instead.

The components

2 components in Captions. Each card plays its own default scene — open one for its props, the source file shadcn add writes, and a player you can scrub frame by frame.

Install

Components are installed into your own Remotion project with the shadcn CLI, and the file it writes is yours to edit — there is no snapcn package to depend on. Set the registry up once, then add components by name:

$ pnpm dlx shadcn@latest add @snap-cn/word-captions

That writes components/snap-cn/word-captions.tsx. Swap the name for any other component on this page.

Put it on screen

Every prop has a working default, so the component renders as soon as it is mounted — give it a composition and you have a video:

// src/Root.tsximport { Composition } from "remotion";import { WordCaptions } from "@/components/snap-cn/word-captions";export const RemotionRoot = () => (  <Composition    id="WordCaptions"    component={WordCaptions}    durationInFrames={96}    fps={30}    width={1280}    height={720}  />);

durationInFrames is the length WordCaptions is choreographed for — 96 frames at 30 fps. Cut it short and the animation is cut short with it. To use one as a beat inside a longer video, mount it in a <Sequence>of the same length instead of giving it a composition of its own. Each component's page lists its props; they are all plain values, so anything you can compute you can animate.
