Viking? Sacrifice

[ChasManiac]

Looking for a Vikings or medieval or fantasy movie/TV series with a sacrifice scene.

I saw some scenes from a movie or a TV series like Vikings. They were part of a fan made music video for some Viking like music. But I can't find the music video again. Or the movie/series. The scenes were of 3 teen girls, dressed in white and placed into rowboats to be sacrificed. The boats were filled with sticks and their hands and feet were tied. The boats were pushed into the water and then they shot fire arrows into the boats. As the boats floated away, the girls start to look terrified. They know what is coming. But there is no escape.

The music video had scenes from Game Of Thrones in addition to the sacrifice scenes. I have watched the series Vikings and the scenes are not from that series.
