Guide - How to Add Auto-Generated CEA-608 Closed Captions to Your Live Streams Using vMix and OBS

Live captioning done by human beings is the most accurate way to generate closed captions for your live streams. However, this can be labor-intensive. For many feeds, automatic closed captions can be “good enough” for most users.

This guide will walk you through, using vMix and OBS, how to embed CEA-608 closed captions into your live streams.
