We have decided to have a piano track playing for our entire title sequence, it is non copyright as we are recording it ourselves; this is the same for all our audio - including the scream.
We will not be getting any of our audio online, and will record it all using sound recorders from school. We are also going to record some of the dialogue in our sequence so that we can delete the audio in the video, thus reducing the crackly sound in the background.
