Are there any accessibility issues with adding media to the intro or title slide of a course?

Hi, Articulate community!

I've often heard that it's a bad practice to add narration or media to the introductory or title slides of an elearning course, due to accessibility issues.

For former teams I've worked on, I believe it was mostly related to issues with the opening slide and the ease of enabling captioning on the media player. There may have also been something with the LMSs that we were publishing to (I formerly worked on content published to Cornerstone; these days, my team uses Docebo).

Currently, the template that my team has developed and is working with have a brief intro animation with music. Additionally, we have one layout in our template that has some video on the title slide.  None of the audio or video on the title slide impacts the ability of the learner to understand the content.

In short, I wonder if there are any accessibility concerns in including media on the initial slide or title slide for an elearning course. Currently, we might have a situation where a brief intro animation triggers to advance at the end of the timeline to a title slide that may also include some video content. That title slide also includes a start button that the learner must click to start the lesson.

Does anyone see any accessibility concerns here?  Thanks in advance for any advice!
