Do you like the animated elements in Wondershare Filmora? Do you want to learn how to make your own?

A little while ago, we posted a list of YouTube channels where you could get free green screen effects . All of these effects consisted of animations on green backgrounds. To use them, you pull the clip into the PIP track of your Filmora project and use the green screen feature to make the background transparent. It’s pretty easy.

In this post, we’re going to kick things up a bit. Here is a list of places where you can get free lessons on creating your own animated video effects.

Animated Video Effect Courses:

Bloop Animation

Most of the video animation courses on this site are paid, but they have a lot of cool free tutorials as well.
