Copyright laws or similar intellectual property laws usually protect creative works or excerpts from such works but not the ideas nor techniques that were used to create these works.
What you intend to do should be safe. Compare it with writing a story, where the final work is of course protected, but not the language itself, nor the plot ideas, structural decisions etc. Likewise, the steps to achieve a certain animation are not protected.
However, there is one tiny exception: source code. Some animation tools, like After Effects, let you write short scripts or expressions to enhance animations. Theoretically the code can be protected by copyright, but only if the code shows enough originality. There is a certain threshold of originality required to be protected, however it depends on the individual case where the threshold is. As a rough rule of thumb, if there are only a handful of lines of code then the script will most likely be too trivial to be protected. Also, if there are no alternative ways to write such a script because the environment dictates the lines of code, then you can safely copy and paste other people's code. Most of the time this will be the case.
