This all started because I wanted to test the audio interface feature on my Zoom H2. I recorded the video using the video camera on my mac and recorded the audio (using the Zoom H2) directly into Audacity. To elongate the e minor chord I used Max/MSP, specifically the Sogs~ object.
Sogs~ doesn’t come with Max but you can get it from the Ircam website. You can download it (along with a couple other useful objects) for about $40. I am willing to pay the money because I use it all the time. Here is a screenshot of the sogs~ help file that I used in this video (click on the image to see a larger version):
For the next step I used the free program, Spear, to add a few artifacts to the “suspended” e minor chord. Here is a screenshot of Spear (again, click to see a larger version):
Finally, I combined the audio and video using Final Cut Pro.
