Once I got all the little thumbnails sketched out, I strung them together with a temporary soundtrack to get a rough idea of shot durations and timing. The soundtrack consists of music that I chose to suit the mood of each scene, ranging from Wagner to Henri Mancini to Slayer. I brought the volume way down and added another audio track of metronome clicks derived from each piece of music, so I have a really prominent click track playing over top muted musical tracks. I cut the thumbnail sequence to this click track. Then I rendered each scene out as a quicktime movie to be used as a template in Flash. More on that in another post.
