# How to use Real-Time Messaging Protocol (RTMP) on EventX?

**Objective:** Set up an RTMP livestream from OBS Studio to an EventX session using the portal's built-in streaming tools.

EventX supports two live streaming protocols:

| Protocol               | Latency     | Recording                         |
| ---------------------- | ----------- | --------------------------------- |
| **RTMP**               | \~15s delay | System recording available        |
| **WebRTC (WHIP/WHEP)** | <3s         | Not available; record on OBS side |

## Prerequisites

* **OBS Studio** installed ([download](https://obsproject.com))
* **RTMP** tool visible in your EventX portal (contact your Project Manager if not)
* An active external streaming source (e.g., Zoom, YouTube Live)
