Step 4- Navigate to Live Auto Captions Module

Once signed in, click into the Live Auto Captioning module located at the top of the page.


Step 5- Click Facebook

Click the linked Facebook page that displays under Schedule New Event located on the right-hand side of the page.

Step 6- Confirm Event Time

The event time that displays within 3Play Media will be based on the time that event was scheduled for within Facebook.  

Step 7- Set a Target Maximum Delay 

Drag the dial button to the right of the screen to increase the Target Maximum Delay and to the left of the screen to decrease the Target Maximum Delay in milliseconds. This sets a delay between the stream we receive and the captions we output. The more the delay, the more accurate the output. The Target Maximum Delay defaults to 2000ms.

Please note: Do not delay the stream within the hosting platform and/or encoding software/hardware.

Step 8- Filter Possibly Offensive Words

Select from the following options from the dropdown menu: None, Normal, High, or Strict to filter possibly offensive words.

Please contact your Account Manager for more information about this setting. 

Step 9- Set Event Wait Time

Step 10- Set Event Max Time

Enter the duration in minutes of the live event to be live auto captioned. 

Set Event Max Time field 

Note that this feature will determine the maximum length of the event and also act as a failsafe in case the streams are not manually stopped at the end of the live event.

Step 11 - Keep Stream? (RTMP only)

Check the box next to Keep Stream? and 3Play Media will store the source video from a live event's RTMP stream. Keeping the stream will allow for additional services to be ordered upon completion of the event including an upgrade path to full transcription/captioning services.

If an RTSP stream is used for the live event or RTMP is used but the option to capture the video is not selected, the source media can be added to live auto captioning file once the event has concluded to allow for other services to be ordered on the file.

Step 12- Edit File Name (optional)

Edit the file name if desired. If not edited, the default file name will be the name of the event that was scheduled within Facebook.

Step 13- Provide a Wordlist (optional)

To improve accuracy of automated captions for a scheduled Live Auto Captioning event, add a Wordlist of the proper nouns, terms, and phrases unique to your organization that may be commonly used during the event.
