As a workaround, brave://flags Hardware-accelerated video decode = disabled gets around the issue. I do not recommend this to others as a fix.
I have also observed this issue with embedded video content in Twitter, and I believe that this could be related to the ITvx thread (New version of Brave breaks ITVx streaming site - #8 by The_RiViT). There is some minimal support that this problem is wider spread here: (https://www.reddit.com/r/brave_browser/comments/126zbxb/youtube_is_way_too_laggy/)
