Have to agree with others that this looks like an episode of FanboysGoneWild, but there are reasons to question, if not outright ceasing to use Brave and they center around their CEO, Brendan Eich. https://www.nytimes.com/2020/12/22/business/brave-brendan-eich-covid-19.html
I’d settle for a good, consistent source for subtitles, let alone audio. The DMCA is a plague on fan cleared content. :(
