 ## What is a Replay?
 
-A replay is **not** a video recording. It’s a video-like reproduction of a user session, built using the  [rrweb recording library](https://www.rrweb.io/).

Replays are created from snapshots of your web application’s DOM state (the browser’s in-memory representation of HTML). When each snapshot is played back, you will see a video-like recording of what the user did throughout their entire session. The user session includes any pageloads, refreshes, and navigations that happened while the user was on your site.

-A user session starts when the Session Replay SDK is first loaded and initialized. The session will continue until 5 minutes passes without any user interactions with the application **or** until a maximum of 60 minutes have elapsed. Closing the browser tab will end the session immediately, according to the rules for [SessionStorage](https://developer.mozilla.org/en-US/docs/Web/API/Window/sessionStorage).

+The session will capture any pageloads, refreshes, or navigations as long as the SDK is re-initialized on the same domain, and in the same browser tab, each time.
