First video: Disappearing and appearing shirt buttons. Disappearing, appearing, and shapeshifting rings. Ear appears to be bluescreened despite the rest of the person appearing to be in front of a real background. Belt buckle slides unnaturally.

Second video: Shadows reveal inconsistent lighting direction. Disappearing and appearing studs on the watch strap. It also has bizarre clothing design with buttons on a non-opening shirt and what seems to be a printed fake weaving pattern that doesn't actually correspond to real weaving, but this could theoretically be made in reality.
