Let's explain a bit the animation techniques.
So, for starters,
remember that animation is an illusion,
so everything you see is not real.
Even I am not really moving now.
You're just seeing a semplification...
...of the movement I made right now,
because the video camera takes thirty frames per second,
which simplify my movement...
...and create the illusion, but you don't really see the movement.
This illusion works incredibly well.
How does animation work?
Animation consists in:
instead of taking someone who is really moving,
and using a movie camera to record their movement...
...and creating a simulation,
we do the opposite.
There is no movie camera in animation.
There is none.
You don't need the techonolgy of the machine...
...recording you with thirty frames per second,
because each picture can be taken...
...potentially even years later.
Animation is that illusion in which I, human being,
take pictures whenever I want,
to create the illusion that something that can't actually move,
it's moving.
