I used two relatively simple softwares and made a good mg animation, which is suitable for beginners. Here I recommend:

First, colorful animation masters

This software is suitable for beginners to do mg animation, because the operation is stupid and easy to use. Secondly, the software has various templates to choose from, including characters and scenes, which saves the trouble of making materials and saves time for beginners.

Second, flash

This is a creative software integrating animation creation and application development. In the final analysis, it is a mixture of "mask+tween animation+frame-by-frame animation" and components (mainly movie clips). Through different combinations of these elements, ever-changing animation effects can be created. The most basic operation is to find a way to make the graphics move.
