The Principle of Slow In and Out defines how objects often start slowly before they get to their full movement. A runner begins by slowly pushing off starting blocks, a car that is about to peel out has a few moments of speeding up before it's energy overcomes friction. This subtle, yet incredibly important Principle, will make all the difference in making animation better.
- The principle of slow in and out…is all about overcoming inertia…whether you're standing still or moving very quickly.…For example, this runner is about to take off at full speed…but before she begins she needs to slowly get into position…and then slowly push off her running blocks.…Let's watch.…Note how she slowly leans down.…Now I know that isn't because of gravity,…but she's slowly getting into position,…and this is a great thing to add to your animation.…
Now watch right as she pushes off.…She doesn't move that much in the first step,…but in the subsequent steps she takes off really fast.…This car is about to peel out on the dirt,…but before he begins he needs to slowly lurch forward.…Let's watch.…Also, do you see the wheels?…Look how quickly they begin to turn.…Yet overall, the car isn't really moving…that much in the beginning.…Combining slow movements with tiny fast movements…will add a lot of physicality to your animation.…
Now this gunshot is great.…Even though it's a really high-speed camera filming it,…
