Thanks everyone – that's exactly what I was thinking, Patrick. The content of the video has yet to be determined, but I was envisioning providing a transcript as well.

Thanks!

If it's "video only" (no actual audio track at all), the simplest
approach (assuming the video does indeed convey information, and isn't
just "visual fluff/interest") would be a transcript, per
https://www.w3.org/TR/WCAG21/#audio-only-and-video-only-prerecorded<https://www.w3.org/TR/WCAG21/#audio-only-and-video-only-prerecorded>.
Otherwise you have to start dealing with providing controls for the
audio in the page as well.
