In order to be able to fully implement Live Auto Captions within 3Play Media, you must be the Host of the Zoom Meeting!

‚ě°ÔłŹ Step 1: Schedule The Meeting Within the Zoom Web Client


zoom navigation bar


Login to and schedule a meeting.


zoom schedule a meeting page


Schedule the meeting for the right time, adding any other information and settings necessary. If the preliminary Zoom and 3Play linkages have been successfully created, most of the settings in a meeting will not have an impact on the live captions and should be set based on personal preference.

Only the meeting ID will have an impact on the necessary steps to get live captions.

If Generate Automatically is selected, please continue with the rest of this guide. If Personal Meeting ID is selected, there will be an additional step outlined later in Step 2.


‚ě°ÔłŹ Step 2: Schedule the Event¬†

Part 1

3Play Media My Files page


Navigate to your 3Play Media account and click Live Auto Captioning in the top navigation bar.

(In order for this step to work, you must have the Zoom integration set up properly)


schedule new event section in 3Play Media


Under the Schedule New Event section on the right, select your Zoom integration.

Click the dropdown menu and select the appropriate user. All users in the linked Zoom account will appear.

All of the scheduled meetings for that user will display.

Check the box of the Zoom meeting that needs Live Auto Captioning, enter a start time and date, and click Schedule. The scheduled time for the Zoom meeting will appear as the default time, but any time can be selected.

The time selected here will be the earliest that 3Play live auto captions can be used on this meeting. This is the time that the 3Play live server will become available, and if this time is set after the beginning of the meeting, the captions will not be available immediately. In order to make sure captions are available in time for the participants to enter the meeting, it is best to schedule the 3Play captioning event 5 to 15 minutes before the scheduled time of the Zoom meeting.

Note: events are scheduled using Eastern Time unless the Time Zone Module has been activated and a new timezone has been configured at the user level.

If ‘Generate Automatically’ was the setting selected when setting up the Zoom Meeting in Step 1, please skip to step 3.¬†

After both the Zoom meeting and the 3Play Captioning event are scheduled, a Stream URL and a Stream Key need to be added to the Zoom meeting in order to use live captions with a personal meeting ID.

The correct Stream URL and Stream Key can be found in the pending 3Play Live Auto Captioning Event.

‚ě°ÔłŹ Step 5: Begin Live Streaming the Meeting


more option in zoom meeting


Return to your Zoom Meeting. On the bottom bar, click More > Live on Custom Live Streaming Service.

*This should be done at or shortly after the Live Event start time scheduled in 3Play.*

If the event in 3Play is schedule for 3:00 pm but you attempt to go live at 2:58 pm, the 3Play live server will not be ready and the meeting will not be able to go live. Please wait until the 3Play live captioning event start time to try again.

As a warning, going Live on Customer Live Streaming Service will open a web page to indicate that the meeting is in the process of going live. The Zoom meeting will persist, and that window can be closed at any time after the meeting has successfully gone live.

If a personal meeting ID was used for the meeting, and the direction is step 2 – part 2 were¬†not followed, the¬†Stream URL and¬†Stream Key from 3Play’s corresponding live event (the one schedule in step 2 – part 1) will now be needed. The web page will open and ask for these details, which can be found on the 3Play live event in the 3Play account system.

For live streaming page URL, enter or any website. This field is required but has no bearing on the zoom meeting or the live captions.

Captions should now appear within 5-10 seconds.

If you get a message from Zoom such as the one above saying “unable to live stream to the custom service”, please confirm the correct Zoom API token was pasted into 3Play in step 4.

If so, Zoom is likely encountering high traffic, and captions will likely appear within a minute or two.
