I got through YouTube by searching for speed run “mm:ss” since speedrun videos usually have the speedrun time in the title. Then it’s just a matter of searching for speed runs of slightly shorter times than it until you happen across a video which is both of appropriate length plus or minus the one second tolerance it gives, and which doesn’t kill either your Roman numerals or elements

Only uppercase letters get treated as Roman numerals, same for periodic table. The real killer one for those two is YouTube url
