Need to add real-time closed captioning to your live stream? We can help in just a few steps! Videolinq is integrated with the most popular hardware and software closed captioning publishing tools. Through our partnership with leading closed captioning vendors we help traditional closed captioning systems send captions also to video on the web. The following use cases cover the most common workflows our customers use.
Use Hardware Encoders
If you do not have closed captioning decoders skip this step and move to option 3. Customers with hardware closed captioning decoders have three ways to send closed captioning data to Videolinq –
(a) Insert captions over SDI and use video encoders that support closed captioning over the SDI signal.
(b) Send the captions data from the EEG encoding device to Videolinq (models 490-492). Contact EEG for instructions.
(c) Extract the closed captioning data from the hardware encoder with a USB cable (EEG, Link Electronics, Evertz, or Norpak) to a Windows desktop application (Telestream CaptionMaker Live or Captions; EEG iCap; 1CapApp 1Fusion; or our own Videolinq VLcap software for Windows operating systems) and send data from the desktop application to Videolinq.
On-Prem Caption Solution
Videolinq partners with closed captioning automation software companies. Voice Interaction is an enterprise solution to process speech-to-text. From the Voice Interaction dashboard select Videolinq as the target output. Use the closed captioning credentials provided in your Videolinq channel and send captions to live videos.
Human Captioning
Many customers do not need to purchase expensive hardware or software. If they have a one-time event or only a few events per year, it makes sense to hire “stenograph operators” as they are called and contract them to capture audio from your event (via phone or online) and use their equipment to send closed captioning to your Videolinq live stream. Closed captioning service providers, will charge about $100-150/per hour, depending on how many hours you will need their service. Use your own service provider or contact us for recommendations.
Automated Captioning
Use Videolinq's automated closed captioning service to insert closed captioning into your video source. Use EDIT to increase accuracy. Read about the difference between human to automated closed captioning.
Recorded Media with Captions
Upload MP4 and VTT caption files, and use them as a source for a live stream. This article explains how to achieve this.
Summary
Regardless of your use case, Videolinq can help you add closed captioning to live streams. You can use recorded media with captions files and "simulate" a live broadcast. You can stream videos with built-in CEA-608 captions already in the video. You can use stenograph operators to insert highly accurate captions to your stream. And now, you can also use automated AI-based closed captioning to generate real-time closed captioning from a video source, correct mistakes the AI software makes (last names or special terms), and increase the accuracy of input text to your closed captioning feed. When the captions are on the video, we deliver them to our own player, or to your preferred player. We also let you include closed captioning in individual streams sent to social media or 3rd party video services and CDNs.
