Bounce In

Each word springs up into place with a little overshoot the moment it is spoken, and the phrase builds word by word

Installation

$ pnpm dlx shadcn@latest add @remocn/caption-bounce-in

Usage

CaptionBounceIn takes a timed transcript and renders only the text block, so place it inside your own AbsoluteFill. Every word stays hidden until its own start time, then springs up from just below its slot. The space for the whole phrase is reserved from the first word, so the line never reflows as it builds. See Positioning for safe placements and Get a transcript for producing captions.json.

tsx

import { AbsoluteFill } from "remotion";
import { CaptionBounceIn } from "@/components/remocn/caption-bounce-in";
import captions from "./captions.json";
 
export const MyScene = () => (
  <AbsoluteFill
    style={{
      justifyContent: "flex-end",
      alignItems: "center",
      paddingBottom: 108,
      paddingInline: 192,
    }}
  >
    <CaptionBounceIn captions={captions} />
  </AbsoluteFill>
);
