For some reason, youtube will choose and random moment/frame of the video you uploaded as your video cover preview or whatever you called it if you did not make one yourself.
I found one of the cover preview frame that youtube choose for me was really interesting, so I play the original video again, and screenshot the interesting moment I found that close to the one that youtube has chosen to show you guys why I love taking videos, cause you can screenshot the moment you liked to create a new “photo”!!!
