The programs you need...

Well let me think, there are many different programs that are free, and that you can use to animate. Here is a list of a few below.
------------------------------------------
Blender:
I highly recomend blender, its completely free and is one of the best animating programs out there. You can download it at Blender.org. It moderatly difficult to use
Efficency = Good
Difficulty = MODERATE
Recomended = HIGHLY
------------------------------------------
Mineimater:
Mineimater is a very simple program and is also free. However everything is at a price, although i recomend it for beginers, its not very good qaulity. The animations come out blury with bad motion and is'nt the best if you want to go pro.
Efficency = Terrible
Difficulty = EASY
Recomended = for beginners
________________________________
Cinema 4D
Although cinema 4D is very hard to use, it will always have the best result. The animation will come out like a movie. Its very awsome or it seems so... Until you see the big $$$ sign. This program can range to about $3,000. Yah soo not very good.
Efficency = Good
Difficulty = Medium
Recomended = nOt ReAlLy $$$
