Stumbled upon this great little worflow piece by Chris Woods on Animation Action Analysis. He talks about his workflow as it relates to him doing lots of animation for TV. He says that in TV, time constraints limit the amount of polish and planning that can go into your animation. So he has been determined to get a workflow that will allow him a fast way to breakdown his animation and hit his deadlines with quality work. He lists his clear ways that he breaks it down using thumbnails and he has plenty of Quicktimes to frame through.
