Control Again The Captions Workflow

Videolinq helps caption operators improve live broadcasts workflows. Broadcast customers should manage their live stream distribution. Ask your customer to subscribe to Videolinq directly and share the publishing credentials to create an event on Streamtext.

Focus on what you do best, and give your customer back the control they need to broadcast their live streams to 25 destinations at the same time!

All that, at no cost to you, the CART operator!
