3D transformation

Animate 2D objects through 3D space with exciting new 3D translation and rotation tools, which allow you to animate along the x, y, and z axes. Apply local or global transformation to any object.

Procedural modeling with Deco and Spray Brush

Turn symbols into instant design tools. Apply symbols in a variety of ways: Quickly create kaleidoscope-like effects and apply fills using the Deco tool, or randomly spray symbols across any defined area using the Spray Brush.

Metadata (XMP) support

Add metadata to SWF files using the new XMP panel. Quickly assign tags for enhanced collaboration and better mobile experiences.
Authoring for Adobe AIR

Deliver interactive experiences to the desktop with new integrated capability to publish to the Adobe® AIR™ runtime. Reach even more audiences across more devices — web, mobile, and now the desktop.

Inverse kinematics with the Bones tool

Create chain-like animation effects with a series of linked objects, or quickly distort a single shape using the new Bones tool.

Motion editor

Experience detailed control over keyframe parameters, including rotation, size, scale, position, filters, and more, using the new motion editor. Refine easing control with graphical displays similar to those in After Effects.

Motion presets

Jump-start your project with prebuilt animations that can be applied to any object. Select from dozens of presets or create and save your own. Share presets with others to save animation time.
