Hi!

Thanks for contacting us and sorry for your issue. On your category page, only the intro/teaser content is being rendered—so if your MP4 video is added inside the full article content, it will show on the single article page but won’t appear in the category/blog view.

What you can do:

Move/add the video to the Intro Text (not only Full Text), so it’s available in category/blog layouts.

If you’re using SP Page Builder to display blog articles, make sure the addon/layout you’re using is configured to output intro content (or supports rendering media in listings). Some listing addons only show title + intro image + intro text.

Alternative: add a thumbnail image in the category view and link to the article where the video plays (common approach for performance).

Regarding autoplay issue, most browsers only allow autoplay if the video is muted. So use:

autoplay + muted + playsinline (especially for mobile)

Example behavior: autoplay with sound is typically blocked unless the user interacts first.

-Regards.
