Storyboarder from Wonder Unit is my new favorite pre-production software. I can now quickly generate professional looking storyboards in minutes. Oh, did I mention it's 100% free and open sourced?
(Disclaimer: I am not being paid by Wonder Unit. I just happened upon the software and thought I'd share!)
The interface is clean and intuitive.
My favorite feature is the shot generator. Simply describe your shot and you'll be presented with multiple options. The generated images are a big improvement on my usual stick figures. If you have some artistic chops you can sketch your own scenes using the robust tool set provided.
The crowd pleaser is no doubt the ability to roundtrip with Photoshop. Think of it as a Adobe Dynamic Link Light. Granted, text layers and blend modes aren't translated unless you rasterize the layers but it's an incredibly powerful addition to a really slick piece of software.
Export PDFs of your storyboards dictating custom image size and column numbers.
There's even an option to export an animated Gif, complete with custom shot timings. This is perfect for that client/boss who "just needs to see it".
I've used this software on my last two pitches and received rave reviews. If you're looking for a better way to storyboard give it a try. I hope it helps you too.
