Different uses for Flipbook

Have you ever used Sketchbook Pro to sketch a concept, then annotated it, adding other sketches to try to get an idea across? Next time, create a flipbook. Imagine sending someone a sketch that comes to life to better illustrate your concept. With Flipbook, you can create cell animation, a prototype, or proof of concept.

Flipbook is not a complete animation package and does not replace animation production software; it is a ‘sketchbook’ of sequential animation. It has all the familiar tools and simplicity of Sketchbook Pro, keeping it fun and creative.

• Use Flipbook to create quick animations that communicate motion and pacing of a sequence.
• Use the timeline as a storyboard, where each frame is an individual board or page. Flipbook lets you see them all together in a sequence, and can also export them as individual images.
• Or use the timeline to create multiple iterations of a character or design and use the animation playback as a way to visualize all the concepts at once. You can also import a single image or photograph as a background, and do iterations of it as paint-overs on individual keyframes
