A new partnership between StreamText and Videolinq helps broadcasters add real-time closed captioning on live video sent to social media platforms and other video platforms or CDN's. The workflow is simple, cost-effective, and efficient. All you will need is a stenograph operator, access to a StreamText account, and any Videolinq plan. Here is what you need to do:

Step 1

Open a Videolinq account and login to the media dashboard. Create a Channel, a destination(s), and a video Source. Important: only video from an RTMP source is supported to add real-time closed captioning to a live stream.

Step 2

Click the "CC" icon under the channel preview player. Select the 3rd option "Closed captioning is not in the video" and copy the credentials.

Step 3

Open a StreamText account and schedule an event. Videolinq options are under the "CARTCaptioning" tab. Copy the "server address", "stream key" and "password" credentials from Videolinq. Adjust buffer and line length as needed. Click on "Create Event".

  • The correction buffer is used for captioning platforms that cannot buffer the output on their end. This buffer will allow you to have your translations complete before they are sent to the video. If you notice duplication in the CC then you may want to try increasing this duration.

  • The default line length is 32 but can be adjusted as needed.

Step 4

Back at the Videolinq dashboard, click on the "Encoder" tab and copy the RTMP path and stream key to your RTMP encoder. Start your RTMP encoder. Video will show in the preview player.

Step 5

Ask your stenograph operator to send captions data to the StreamText service. Start the StreamText event. A CC icon will show up on the preview player upper right corner. Enable captions to see them on the preview player.

Step 6

Click “Go Live” to activate the channel. Video with closed captioning is now available in the channel. Create a player to embed on your website, or add destinations to send video + closed captioning to supported social media platforms and 3rd party streaming service providers. Video with closed captioning will display on supported platforms and services. Viewers will be able to enable/disable closed captioning on their players.
