Developers often wrestle with building frame‑accurate feedback loops for video reviews. Traditional solutions require custom back‑ends, sync logic, and a UI that lets reviewers jump to exact moments. By plugging the Velt SDK into a Next.js app, the tutorial shows how to recreate Frame.io‑style commenting with far less code.

Pre‑built components handle timestamped comments, display them in a sidebar, and render bubbles on the Video-React timeline, while the VeltProvider supplies real‑time sync across users. The example identifies two mock reviewers, John Doe and Jane Smith, using the useIdentify hook, then sets a document ID to scope comments. Clicking a comment pauses the video, seeks to the stored timestamp, and updates Velt’s location context, ensuring every participant sees the same frame.

All source files live on GitHub, and a local dev server runs with a single “npm run dev” command. This approach cuts weeks of engineering effort to minutes, letting teams focus on creative decisions rather than plumbing.
