Diegetic and Non-Diegetic Sound

The clip opens with some music, which is a an example of a non diegetic sound, as it has been added in  during editing. At the same time that the music starts, which is at 0:09, there is the sound of dust blow, which is a synchronous diegetic sound as the character sees the dust blowing in front of them.

At 0:18, a voice over begins, which is an example of an asynchronous non diegetic sound. 

At 0:42, the is the sound of a TIE fighter ship as it plummets towards a planet.

At 1:09, over the non diegetic voice over and music, we can hear the sound of ships flying, which is a synchronous diegetic sound as we can see the ships that are making the noises.
