I think I stumbled onto something. There's a lot of these youtube channels about salaryman life that have AI video thumbnails and the videos are all POV shots of the "salaryman" walking around with no voice narration, just subtitles in english.

I wonder if they just lift the footage from somewhere and add their own subtitles to farm views? What do ya'll think?
