The video looks relatively old - maybe, 1990s or 2000s.
The celebrant is a real Roman Catholic priest, Anders Piltz. This took place in Visby, Gotland island, Sweden. The congregation are locals, wearing distinctive 15th-century clothing; the church interior also looks very medieval, while the priest’s balding head stands for a tonsure, I guess.
The priest is a Dominican; so, it is no surprise that the Dominican Rite is used (note the gestures at 45.30 and 46.05). This is supposed to be an Ordinary Sunday, but the vestments are read - is it a Dominican Rite thing?
It looked to me quite an impressive recreation. I wonder whether it is intentional or accidental, but the gospel reading at this Mass was exactly the same as this week’s traditional reading!
