Yep, it is convincing. And it seems the video is performed by a human, although I did think it could be AI. They say in the description:

After saying it is AI:

> How people was touched by this version of « Papoutai » by stromae made by AI, I was also touched as y’all, as an independent Artist I wanted to put my emotions and my soul on this masterpiece
