This is the Khorasan group which “refers to a group of senior al-Qaeda members who operate in Syria.”. (see wikipedia, here) The video goes into some detail identifying members of the group whilst also concealing others with some basic mask overlays. 

The video shows the group riding on horses which is a prelude to the beheading of a soldier the group has captured.
