This is the first attempt at adding sound to the video.
It was a particular challenge due to the fact that the program I compiled the sound on (Audacity--a free sound editing program) was done at home and the video editing program (After Effects--very expensive program from Adobe) was done at school.
I had worked on the video first and knew generally what I wanted for the sound, but this was before we created the sound files to be used... my surprise. When working on the sound files at home, I kept exploring smaller and smaller sound-bites. I would work for an hour on mixing two or three clips which were each a couple of seconds long, all with a ticking or thumping quality. I would find my interest gravitating towards the sound Between the ticks and thumps. Ambient sounds from the room when the whole class was recording their particular sounds became a focus for a few hours...
I was not recording to match up with the video. I was trying to create an interesting soundscape out of the raw soundclips. I ended up with a soundfile of about 45-50 seconds.
I would play the soundfile in a loop and then play the silent video in Quicktime, trying to match the start times, to see what kind of mess or mix I made. Two unplanned moments stood out, which I further developed. The first was the obvious matching the ECUs (close ups) to the double coughing. The second was the long heavy breath when the camera travels down the leg; this quickly became central transition moment.
I brought the soundfile down to about 35 seconds to match the video. I did not like the ending, but brought it to class to show.
