Looks completely fake to me. The face moves very unnaturally and doesn't even stick to the body properly. It looks like a super realistic mask (meaning it has many of the same problems a mask has).
I was about to downvote you until I read your comment after watching the video.
This video leads me to believe that there will soon be a time when popular people will just pick some pre-made advertisements. No need to go and film it since that has already been done without that person. We'll then accept deep fakes as a valid marketing strategy (or whatever purpose may come up), until some protests require them to be watermarked.
In Slovakia we've already had a deepfake ad of a well-known news anchor.
The ad starts as a news segment where she says that it turns out the covid vaccines don't work and then pivots to awareness campaign about hoaxes and misinformation.
