W3C outlines good recommendations for audio descriptions (linked below) as follows:
MSU provides access to TechSmith (linked below), which can be used to generate closed captions and/or add an audio description track Log in with your NetID to upload videos that you want to add captions or a description track to.
For instructions on how to add captions, and/or an audio description track in TechSmith, see the links provided below.
