Cvent: Schedule Live Captions

This article explains how to schedule 3Play auto-captioning for Cvent Live streams.

In order to set up 3Play auto-captioning for your Cvent Live streams, a Cvent account needs to be linked to a 3Play Media project. Follow the directions in this article to link 3Play Media and Cvent accounts.


The 3Play Media Live auto-captioning module will also need to be turned on. Please contact a 3Play Media account manager to have this module turned on.


Please note: Zoom is not currently supported as a video/audio source for captioning delivery to the Cvent platform. In order to enable captioning delivery into Cvent, a different video/audio source, or encoder (such as OBS) will need to be used. 


Step 1- Schedule Cvent Live Event in 3Play Media

Sign in to 3Play Media and click Live Auto Captioning in the top navigation bar. 


Step 2- Within 3Play Media Click Schedule Live Captions 


Step 3 - Navigate to the linked Cvent account


If there is more than one Cvent account linked to your 3Play Media project, you might have to select between them.

Step 4 - Schedule live captions for a live stream. 


Select the live stream that requires captions. Select the time that the event is scheduled to start, and select the time that captions should begin. Note, the scheduled start time is the earliest that the captions can actually begin. 


Please note: Cvent events will not populate for scheduling in 3Play until 48 hours prior to the start time of the session.



Step 5 - Click Schedule and Implement Desired Captioning Delivery Method

3Play provides both iFrame and Javascript code snippets that can be embedded onto an external webpage for captioning delivery. These code snippets are available on the scheduling confirmation page, as well as on the Event Details page (accessible from your Live Event Dashboard).

3Play also provides a second screen webpage for captioning delivery, information on how to access this URL is available here: 


Confirm the proper start time and event name of the live stream and captions. 

Step 6 - Configure your encoder to stream to Cvent at your Event Start time 

Cvent will provide you with an Input RTMP URL & Key when you schedule an event in the Cvent platform. Enter this information into your encoder.


For example, if you’re using OBS as your encoder: 

Add the Input Stream URL in the URL field within OBS.
Add the Input Stream Key in the Stream key field within OBS.
Do not enable Use authentication.
