1. Schedule YouTube Live Event in 3Play Media
Sign in to 3Play Media and click Live Captioning in the top navigation bar.
2. Within 3Play Media Click Schedule Live Captions
3. Select YouTube
4. Provide us details about your Live Event
Select the YouTube linked Account and Event
Select the YouTube account corresponding to the live event scheduled in YouTube (if more than one account is linked) by clicking "Select Integration". Then, select a pre-scheduled event in Youtube by selecting and choosing the event under "External Event".
Select Service Type
3Play provides both Live Professional Captions as well as Live Auto Captions. Select the service type for your event using the dropdown.
Add Event Name
Add in a name for your event that will make it easy for you to find the event when searching for it after scheduling.
Enter an Estimated Event Duration
An Estimated event duration is an estimate for the maximum amount of time that your event will last for. 3Play will be ready to provide you with captions through the entire duration that you provide to us using this information.
Enter a Pre-Event Start Time
Different from your event start time, the pre-event start time will tell us how many minutes before your event you'd like to start sending your stream to us. This is before your event start time, and will allow us to listen to your stream before your actual event start time. This is useful if you may start earlier than scheduled.
Streaming to 3Play from your encoder
To allow 3Play to receive your stream and create captions, you will stream to 3Play's caption service from your encoder. As a default, 3Play will provide you with a stream target (transcoder). The RTMP URL address and Key to the stream target are provided on the confirmation page of this workflow; you'll enter this information into your encoder stream settings in preparation for the event.
- You may also elect to use a Reserved Stream Target, please see this support document for additional information. If you do not have a reserved stream target, please set this option to "Use single-use transcoder".
Streaming quality & bandwidth recommendation: 3Play recommends a stream >2mbps.
Caption Delivery
In Addition to posting back to the Youtube player during your live stream, captions can also be delivered to a captions embed, which is a code snippet (iFrame or Javascript) that can be added to a webpage (this requires access to the code through which the embed can be added). The following steps outline utilization of the captions embed.
3Play will also deliver captions to a second screen webpage, additional information on this captioning delivery method is available in this support document.
| Note: With exception of a reserved embed or external web page, your caption link and embed code will be unique to each event. |
File Storage Location
