Check the box next to the Meeting requiring Live Auto Captions.


➡️ Step 8: Configure Live Auto Captions


Start Captions: Once the Meeting is selected note that Start Captions defaults to 15 Minutes Before. This is 3Play Media’s suggested setting as it should allow enough time to ensure the captions will display during the YouTube Live event however it can be adjusted to At Event Start Time, 5 Minutes Before, 10 Minutes Before, 20 Minutes Before, or 30 Minutes Before.

Wordlists (Optional): Click + Add Wordlist to provide any words the inform the automatic speech recognition process. Once words have been added, click Add Wordlist.

Advanced Settings

Maximum Captioning Delay: This will set a delay between the stream we receive and the captions we output. Longer latency will result in a more accurate output. Defaults to 5000ms (5 second delay) however this can be toggled between a 2-15 second delay.

Stream Wait Time: Set an amount of time for our system to wait for the event to begin. Once the determined wait time is reached for the scheduled event and the event has not started, the scheduled captions will no longer be available. Defaults to 30 minutes

Max Stream Time: Set a maximum time for your live captioning event. This feature can be used as a safety net should a live event not be manually stopped. The Max Stream Timewill determine a hard stop for the event as well. If it is anticipated that a live event may run longer than scheduled, factor this when determining the Max Stream Time. Events in your project can be no longer than the Event Max Time setting. Defaults to 240 minutes

Note that when a live event stream is manually stopped this will also override the set Max Stream Time and conclude the live auto captions for the event as well.

Save Event Stream: If enabled, the live stream will be saved as the source for the file after the event. This is useful if service upgrades are anticipated. Leave this off otherwise as it incurs extra processing both during and after the event and costs an additional $0.10/min.

Profanity Filter: Set a sensitivity level for filtering out offensive words. Defaults to Normal however it can be changed to None or Strict.

IMPORTANT: Advanced Settings can be edited up to 5 minutes prior to scheduled start of the Live Auto Captions!

Go to the scheduled Meeting within Zoom and Start the event.
