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.


Under Advanced Settings, verify your captioning delivery method. Captioning delivery is supported through Cvent player 608 encoding (appearing natively within the video player) OR the 3Play Embed (displayed outside of the video player). This selection can also be set as a default at the project level under Live Captioning within the Settings menu in the upper righthand corner of your account. 




Step 5 - Confirm Event Details


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

Step 6 - Click Schedule Event & Copy Input RTMP URL & Key from confirmation page

3Play will provide you with an Input RTMP URL & Key on the confirmation page. 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.



Step 7 - Start streaming at the 3Play event start time

The specified start time in 3Play represents the time at which 3Play will initiate a service to listen for your stream at this time. Do not attempt to stream to 3Play before the event start time, as the stream connection will fail to connect from your encoder to 3Play and your encoder will display an error message.
