This specific video was recorded through a cell phone camera on the day before Epiphany Day on January 6th (according to the Old Julian Calendar; on January 18 according to the Revised Julian Calendar) in 2006, during the blessing of the waters which takes place every year on the same day at the Jordan, in the very same area where Jesus Christ himself was baptized.
This is a recurring annual miracle in the Holy Land on the Feast of Holy Theophany as followed by the Jerusalem Patriarchate. Read Fr. Milovan's article that accompanies the YouTube clip.
"Today the nature of water is sanctified. The Jordan is parted and reverses its flow on seeing its Master being baptised." - Orthodox Hymn for Theophany
