LO5: Changes to the draft work and improvments

The first change that Sam made the text to the introduction clip. He did this because Cal's voice is quite deep on the audio, and as it is a fast cut the audience might not be able to understand the words just from the audio. We also re-recorded the audio as the first take sounded too grainy and unprofessional. I added new sound effects such as the dramatic sound after each word in the introduction, Cal striking the ball, the ball hitting the back of the net and the light switch at the very end. I created an echo when Cal says "...and this is my story", this was to give the trailer a dramatic effect.
