• Hey guys, so I decided to make a video series dedicated to the Twelve Principles of Animation

• as described by the legendary animators Frank Thomas and Ollie Johnston

• So the first principle is Squash and Stretch

• This is the principle that animated objects will get longer or flatter to emphasize their speed, momentum, weight, and mass.

• Here's a bouncing ball that has Squash and Stretch.

• And here's one without Squash and Stretch. See the difference?

• The amount that an object squashes and stretches says something about its mass

• The more squash and stretch, the softer the object

• the less squash and stretch, the stiffer the object

• This first one looks like a water balloon and the second one probably would be a bowling ball

• Squash a stretch applies to characters too.

• Look at how this figure is stretching from the speed that he's coming down with.

• Then he squashes after he lands, before settling in his pose.

• You can also use squash and stretch to exaggerate facial expressions.

• Let's add some squash and stretch to this face.

• When his eyes are closed, his face is squashed, and when he opens his eyes in disbelief,

• his face stretches up and settles back to normal.

• It's very important to keep the volume of the object consistent.

• This is what a lot of people mess up with when they're first trying to do squash and stretch.

• They'll elongate the ball like this and flatten it like this.

• This is what you should NOT do. the overall volume of the ball must be the SAME.

• So as the ball gets longer, it also gets narrower.

• When it gets flatter, it also gets wider.

• The same goes with cubes. If you're going in with one line, the other lines must go in the opposite direction.

• The cube should start out narrow, get flat, get narrow again, and then rest.

• In-betweening with cubes is easy because you can measure the line in between the two lines and then connect them to make the cube.

• If you master squash and stretch with cubes, the next step is to try to do it in 3D.

• Another important note is that the ball does not have to be stretching the entire time that it's falling.

• When it's just starting to fall, it should have its normal shape for the most part,

• and then when it's just about to hit the bottom, that's when it has the most stretch.

• So do not overdo Squash and Stretch in this sense.

• Alright, that is all I've got for Squash and Stretch.

• The next principle will be Anticipation.

• Hope you learned something and I'll see you guys in the next video!
