Features include: full camera setting controls, auto-averaging picture smoothing, onion-skin and strobe and disaster recovery. Frames are saved to a directory when taken, and automatically moved to a trash directory when cut or deleted. Barring a hard-disk crash, you cannot lose a single frame of animation unless you specifically delete it by emptying the trash. MotionMage is written in Java, and it uses the Java Media Framework for video functions. This means that it works with both Windows and Unix/Linux systems.

It also includes chroma key support and multi level onion skinning.
