Hello there @dbcommunity thanks for your report and please accept my apologies for this issue. Could you please provide me with the MacOS version you are currently using?
In the meantime, try opening your main profile in private or guest mode to see if the videos no longer load. If they do not load, try disabling your extensions to see if this is the cause of the issue.
You can open a Guest Window by going to Main menu → Open Guest window:
On your computer, open Brave.
At the top right, click Menu → More tools → Extensions.
On to the extension you want to remove, click Remove.
@dbcommunity does adding that page to sites that can play insecure content? You can do it by going to brave://settings/content/insecureContent > Not allowed to show insecure content > add the site > click /> Sound and Images set to block.
It does auto-play on other browsers as well. I was thinking with the auto-play set to block, it would prevent websites from auto-playing the video. There are quite a few websites which autoplay the video. Another example is the website below.
