Raks Dance documentary

This is part one of a series of three short documentary clips about Raks (a type of dance). At the beginning there is a woman dancing to music talking about the moves she is doing, it then goes on to show a woman sat in a chair talking about the dance, text is used here to explain who she is and where she's from. The video then goes on to show a clip of where the dance originated from which looks like a tribe somewhere, there is a voice-over here however it's not in English so I'm not entirely sure what he is saying. The video then goes on to (what I think) is the voice-over man explaining the history of the dance. There is a series of women talking however again, none of this is in English. I would like to incorporate certain parts of this video in my own, for example the way text is used to explain who is speaking - why, where they're from, what they do etc. I could use this in my video to tell the audience my subject's name, where they were born, how old they are and just general facts and information about my subject. I will also lay my video out like this one as I like the way there are clips of people talking and then it switches to short clips of other things, like the woman dancing and the history of the dance which both have the male voice-over. In my video I would like to do a similar thing - for example, I could have my subject talking in a chair in a room like in this video and then I could switch to a reconstruction of what they are talking about or an old video of theirs if I manage to receive some and then switch back to them in the room. I could also voice-over during the reconstruction/old videos to explain to the viewer what they are seeing and what's going on.
