As media skills - audit editing

To help understand the concept of editing film in class we were told to open Final cut pro - Bait tutorial.
From there we opened up a file that gave us several clips in the browser, we used the I in and the O key to show outpoints in where we wanted it to be edited.
In order to make the sequence we dragged the clips onto the timeline so the clips could connect and begin to make sense.
I also learned to use the razor tool, the razor tool would enable us to cut out what we didn't want to add in the sequence.
As well as everything, i learnt to put in a cross fade effect on the video and add additional audio such as tension building music in the background (non-diagetic).
