Animation blocking and spline versions.

The first video is at the blocking stage of the animation. An animation is said to be in blocking when it only contains the main keys of the story. There's no need to add too much details, as long as you can clearly understand what's happening in your scene.
I think that I really started to understand the importance of a good blocking. Without it it's really hard to end with a good animation.

The second video is the spline version with a lot more keys added to the animation. At this stage I added more details like overlaps, ease ins/outs, solid arcs, and more breakdown keys. I think that I did a bit too much and already tried to get to the final look at this stage. The consequences were that I had too many keys all over the time frame and I couldn't recognize my main keys anymore.

I guess that managing all that mess will better with time.
