TechSmith Relay: Add & Edit Captioning (All Users)

This document provides an overview on how add captioning to your videos.

Closed captioning not only helps students with hearing impairments, but is beneficial for students where English is their second language.  It is also beneficial for students not able to listen to the video due to sound restrictions in their environment (e.g., at work).

See the Add and Edit Captions video for full features.
