Wordly.ai RTMP Studio Setup


When planning to use Wordly.ai for live captioning for your Studio webcast, we recommend providing Wordly with an RTMP connection they can use to capture the webcast audio.

NOTE: You must use a video and audio webcast in order to use Wordly.


Follow the below steps to set up an RTMP link for Wordly.

1. Open the Monitor Tool by logging into Studio and going to TOOLS > MONITOR TOOL

2. Click the OUTPUTS tab on the top left

3. Click the “+” sign and choose YOUTUBE LIVE



4. Add a Title and include Wordly in the title name

5. In Server URL enter - rtmps://media.wordly.ai/live

6. In Stream name/key enter the Wordly Session ID and Passcode

  • Make sure to enter in the same format: XXXXX-XXXX_XXXXXX




For reference, below is additional information on the Wordly portal where the session information can be found.




To add Wordly to your webcast console:

1. Open the Webcast Layout editor and add the Wordly panel to the console.

2. Under Content Options add the Wordly “Session ID"

 3. Click “Apply” and confirm Wordly now displays with the Session ID in the panel.





  • To test the integration with Wordly, start the Studio webcast with a source that is sending audio. This could be a pre-recorded video or someone speaking live from a script.
  • Join the Wordly panel and confirm you can view captions coming through the panel.



When an attendee joins the webcast they have the option to view the captions by opening the Wordly panel and then:

  • Choosing their preferred language
  • The Session ID should be pre-populated
  • Entering their name

Once an attendee joins the captions in the Wordly panel they can click the red "x" to exit the captions. This will not remove the attendee from the Studio webcast, this simply closes captions.




Wordly Text Delay Implementation


With Wordly, the machine translation actually appears ahead of the live speaker of video due to the delay in the stream getting to the attendee vs the real-time translation.  To delay the Wordly stream to match the delay in the video player, you can use the following instructions to add a delay to the stream through the stream keys.
The delay is in milliseconds to allow fine-tuning if needed. So, now a stream key can
look like:
This will add a delay of 10 seconds.  The delay can be adjusted to fit the requirement, however, most recently 11000 milliseconds was used as it seemed the most natural.  

To add the parameter to the Stream name/key from within the Studio:  Go to Tools> Monitor Tool> Outputs>Closed Caption Title> Edit/Pencil Icon
