# File streaming with OBS

> Play a finished file out live with OBS — QuickTime, MP4 and any other format OBS supports.

Playing a media file out live is a great way to run a moderated screening or present a finished master. It works with **any format OBS can play** — QuickTime, MP4 and more — and one person controls playback (play, pause, loop). That makes it ideal for client presentations of final renders and for live moderation.

<Note>
  These steps apply to **both** dfine.io products that livestream — Streaming Classic and Review. The encoder setup is the same; only where you copy your ingest URL and stream key differs by product. See [Where do I find the ingest server URL?](/en/where-do-i-find-the-ingest-server-url).
