Cartoon Animator 5 is a powerful animation tool with features that are sophisticated enough for professional users, but intuitive and easy enough for new animators.

You can create your own animated props by importing a sequence of frames and using Collect Clip to animate them. With Cartoon Animator, you can level up your 2d animation to a much higher standard.

For character animation, Animated Drawings from Meta, comes in handy. It can animate character drawings, provided they are on a white background with the limbs separate and visible.
