Tutorial by: Howard Wimshurst
What a great find! Howard Wimshurst shows us how to create this complex write-on transition, but he uses traditional animation techniques to get us there. Very similar to basic Photoshop Techniques by Shane Dering, Howard does a lot of hand drawn, but uses a program called TVPaint.
TVPaint Animation is a complete and versatile software dedicated to drawing, storyboarding and to 2D traditional animation (including management of soundtracks), and all in a single interface.
No stranger to the 2D animation game, Howard has been around for a while and has some amazing work. Be sure to show your support to Howard for sharing his knowledge!
