This one was a pain in the ass. I shot all 4 parts as I performed "live" to the tracks so it wouldn't be faked lip sync. All in my green wall room. But I had the damnedest time getting the video to play in the editor on the computer I had at the time (2010/windows 7 model) because I had 4 separate video tracks being chroma processed at the same time (computer couldn't keep up). Then had a hell of a time finding a video format that would export with all 4 parts in sync with the mixed audio. I cussed a lot when I made this...so much so that I had to make up new cuss words just to finish the video.
