Story Builder is a free tool from Google Docs that let’s you write a script and instantly have it turn into an animated conversation between several characters, complete with background music and built-in sharability.
I walk you through how to use Story Builder and give you a couple ideas for how you could use this as a part of your future videos.
Story Builder does not create an actual video file that you can download, however, so you’ll have to use a screen capture program to save it as a video to your computer. I use iShowU HD Pro for Mac for screen capture.
Sorry I’m not familiar enough with Windows to know what to recommend for PC. Hopefully someone will recommend something in the comments for Windows users.
