I wanted to use open source [free] software when ever possible. I am really excited to find Celtx. Celtx is an all around software to handle the pre-production of media projects. They have project templates for Film, Audio-Visual, Theatre, Audio Play, Storyboard, Comic Book and Novel.
I will be using the Storyboard template as well as maybe the Film template to put this all together. I will be able to write the script and storyboard the scenes, develop characters.
I really like the storboard template. You can work out the camera directions and also play the storyboard back like a movie when you are done.
Below is a screenshot
They also have a sketch feature so you can work out your camera moves or stage direction.
This is going to be very helpful, and best of all it is free. I really love open source programs, especially ones like this that have been developed to this extent.
