RE: Question on video accessibility

The way to add “Alt Text” to videos is through Audio Description.   A huge collection of great resources is available at What is Audio Description? (acb.org)<https://acb.org/adp/ad.html>.

Subject: Question on video accessibility

Hey all,

I am looking for your thoughts and guidance on video accessibility. If you could suggest, will be very much appreciated.

We have videos where there is just music play in an entire video however important information about the product is also mentioned in text on the screen in the video. i.e. These videos include content that is only presented visually (e.g., on-screen text that is not obvious from the audio)

for example: for a product, text on-screen appears as "won 3 awards in a row", "better sustainability",  "affordable" and much more


My question is how can I make such kinds of video accessible?

Approach 1: use description? ( not sure how that can be used on video), any example?
Approach 2: use aria-labelledby to provide content on screen?
Approach 3: or needed to be hide from screen readers?

could someone please provide an example to which I can refer?

Very much appreciated your thoughts and opinions

Thank you so much!

Kiran
