tags: animations, transitions, frames, useCurrentFrame

All animations MUST be driven by the useCurrentFrame() hook.
Write animations in seconds and multiply them by the fps value from useVideoConfig().

import { useCurrentFrame } from "remotion";

export const FadeIn = () => {
  const frame = useCurrentFrame();
  const { fps } = useVideoConfig();

  const opacity = interpolate(frame, [0, 2 * fps], [0, 1], {
    extrapolateRight: "clamp",
  });

  return <div style={{ opacity }}>Hello World!</div>;
};

CSS transitions or animations are FORBIDDEN - they will not render correctly.
Tailwind animation class names are FORBIDDEN - they will not render correctly.
