We had to alter a video, so I chose a video game I had played and recorded on my PC Rainbow Six, I combined a few of my games together.  I then removed the audio and replaced it with soundbites from movies that I had found on You Tube, '100 Greatest One Liners- Before the Kill' .  I broke my footage into 4 sections and used 4 of the one-liners,  two of which were from Ghostbusters and Chucky.  My main priority was making sure that the shooting from the sound bite matched that of my film footage, and the rest of the audio was entertaining.
