Saw your video, your right to be alarmed! The rapid speed of the rhythmic clunking is key. The member that rotates at that speed is your culprit. Probably not wheel bearing, possibly a roller bearing inside the clutch hub assembly. Check the easy stuff first, and do any checks possible with the cover off to get closer to the origen of the noise. Use a long screw driver as a probe and put your ear against the handle. This is like a stethoscope. Rotating noises like that can fool you so take time to diagnose it.
Don't want to jump too far ahead but that sounds like a chipped gear that is constantly in mesh, and every time the chip meets its mate- you get the clunk sound. From the speed of the noise it's likely internal trans gear noise. But check EVERY thing external first.
