I am a bit excited about this brand-new application. Here is some information about it. You can read the rest of the page along with some videos by following the link at the bottom of this post.
Shot Designer makes it ridiculously easy to block complex scenes, complete with Camera Diagram, Animation, Shot List, Storyboards and Director's Viewfinder. Neither Camera Diagrams, Shot Lists, Storyboards, or Animation by themselves give you a satisfying understanding of camera-blocking -- you have to use them together. Shot Designer gives you a superior understanding of your scene, and is the ultimate Director's creativity tool.
Shot Designer dramatically speeds up the Director's process of making camera diagrams.
Shot Designer is FAST. The app knows how Directing works and does most of the work for you -- like automatically moving cameras when you move characters.
Shot Designer is fast enough that you can use it with even with actors waiting!
