TikTok search by video function?

My friend keeps posting videos that just well, I don’t think it’s him. Specifically motorcycle content, him ripping wheelies 120 miles an hour down the freeway but when we ride together he can barely leave every intersection without stalling and can’t even keep his bars straight….

I think he pirated videos from someone else for clout, but I don’t have any proof. Is there anyway to screen record his video and search it up?
