Practice 01

Steps:

1. First, I create a rectangle in Illustrator.

HDTV 1080p setting under Video/Film Slot.

A rectangle in the center pt.

2.

Setup a new composition HDTV 1080 29.97, duration = 5 sec 25 frames

3. Import rectangle.

Import file/multiple files

As Composition - Retain Layer Size or Footage

4. Plan on a Slime movement from going up to all the way down

A > B > C

A

B

C
Adjust the position with Keyframe, and Plan of A -> B -> C moves

5.

To make it jump, first I scale in down to long and short. Then, reposition.

Upon Impact, I scale down just a little compare to last one. Just adjust a half of it of original rectangle.

Return to shape when Drop down.

5.1 Make it more likely natural.

Upon Drop impact, I scale it to near maximum long and short.

As for Jumping-Hit-Wall Impact I scale it longer just after a frame.

Immediately take a step (square) before change back to Shape just after two frames behind dropping frame.

Back to original shape. After a frame.

5.2 Easing Method.

I easy ease on the move ' Ready for jumping '

Ease out after the impact and change shape.

Easy ease on stationary shape-changing stage.

Ease in when dropping and begin to change shape.

Upon gravity dropping, Easy out upon impact begin to change shape. And Easy ease for final shape.

My comment:
Why does it hang on the roof for a sec, because its a sticky slime. But then gravity pull it all the way down.
