Flower Power
Combining vector art and shapes inside After Effects can yield some
great and unexpected results. In this tutorial, we'll show you how to
set up the popular "popping" animation effect with very little effort.
Then we'll add the new CS4 Wiggle Transform operator combined with the
Repeater to explore some fun and random animations.
All files are for personal use only.
1 PREPARE LAYERED ARTWORK
I always prepare my graphics in Illustrator, because of its vector
qualities. This workflow allows me to keep all the layers (as with
Photoshop) and yields a much clearer and crisper result even when scaled
up within After Effects. One important note: Make sure to set the layer
structure correctly and always name your layers in a logical manner.
Working in an organized way will make the animation process faster,
making life much easier if you need to go back and change things later
on.

2 IMPORT FOOTAGE; CREATE BACKGROUND
Import your artwork into After Effects by choosing
File>Import>File. Be sure to set Import Footage to Composition and
set the Footage Dimensions to Layer Size. The spec for this project
(Composition>Composition Settings) is a squarepixel comp of 720x534
pixels (from the Preset dropdown menu, choose NTSC D1 Square
Pixel these are the new CS4 corrected PAR dimensions for NTSC and should
come up automatically if you set it in Illustrator), 29.97 fps, and 5
seconds in length. Doubleclick the imported comp (ours is "Flower
Power") to open it, ensure nothing is selected, and then doubleclick
the Rectangle tool (Q) to create your first shape background.

3 DESIGN BACKGROUND
Select Shape Layer 1 and in the Toolbar, set the Stroke to 0 px, click
the word Fill, choose a Radial Gradient, then click OK. Next we'll
define two suitable colors that will blend well with the design. Click
on the Gradient Fill icon in the Toolbar and click on each color stop to
set the colors to fit your design (we used dark purple and warm
orange). Press OK to confirm, then return to the Selection tool (V), and
drag the tiny right circle on the screen until you've reached the edge
of the comp, which will define a nice even gradient from the middle to
the edge of the screen.

4 REORDER LAYERS; CLICK SOLO
With the shape layer selected in the Timeline, press Return (PC: Enter),
rename it "Background," and then use the keyboard shortcut
ShiftCommand (PC: Ctrl) to send it beneath all the layers.
Next, we want to set an interesting popping animation that reveals all
the layers sequentially. We only need to set it for one layer and then
use the same settings for the other layers, with minor adjustments as
needed. Let's start by selecting any one of the artwork layers and press
S to show the Scale properties. At this point, I'd also suggest
clicking the Solo switch to visually isolate this layer.

5 CREATE MAIN "POP" ANIMATION
Go to 10 frames along the Timeline and click the Stopwatch next to Scale
to set a keyframe with the current value of 100%. Return to the first
frame (0) and change the Scale to 0%. Next, we want to change the
velocity and the ease so the animation will grow a bit beyond full size
before ending at 100%, and we can use the Graph Editor very nicely for
this. Click the Graph Editor icon in the Timeline, select the last
keyframe, click the Easy Ease In icon to convert the keyframe, then
adjust the curve handle upward to extend the scale above 100%, before it
drops back in.

6 DUPLICATE ANIMATION
Click the Graph Editor icon to return to the regular Timeline view, then
Shiftselect both keyframes for the Scale property. Copy them to memory
(CommandC PC: CtrlC). Now, select the rest of the layers in the comp
(excluding the Background and the layer you're copying from), and Paste
(CommandV PC: CtrlV) to apply the same animation to all of them.
"UnSolo" the layer you worked on originally, then press 0 on the keypad
for a RAM preview, and confirm that all layers now have the same "pop"
scale animation.

7 TRIM AND DISTRIBUTE LAYERS
Our basic animation is now in place, but the timing is the same on all
layers. Let's fix that with a few short steps. First, select the
bottommost artwork layer (not the shape background), then hold down
Shift and select the topmost artwork layer. This is very
important, as it will set the order of the layer sequencing. Now go to
10 frames on the Timeline, press Option (PC: Alt) to trim all the
layers to 10 frames, then Control click (PC: Rightclick) on any
selected layer and choose Keyframe Assistant>Sequence Layers.

8 SET OVERLAP
In the Sequence Layers dialog, check the Overlap box on, set the
Duration to 5 frames, and Transition to Off, then click OK this now
offsets the layers by 5 frames in time sequentially. Now, while the
layers are still selected, go to the end of the Timeline and press
Option (PC:Alt) to extend their visibility till the end. Create a RAM
Preview to see the new results nice!
That was easy, wasn't it? But we're not done yet you'll want to work on
each element individually and set the correct Anchor point, so the
growing effect will take place from the correct part of the layer.


9 ADJUST ANCHOR POINTS
The easiest way to do this is to use the Pan Behind tool (Y). Deselect
all the layers (F2), select your first layer, and then drag the center
Anchor Point to the desired point from which the animation needs to
occur. In this step, we selected and adjusted the Leaves layer's anchor
point, so the animation now occurs from its bottomleft corner. Repeat
this process for each of your artwork layers, and you'll really notice
the difference!

10 EMBELLISHMENT SUGGESTIONS
To enhance the motion, I've added a Rotation spin on top of the scale to
the Lines layer, and for my Rainbow layer, I've used the Radial Wipe
effect to reveal it. You might want to add some changes to the timing to
add more variations to your design.
Next, we'll spice up our scene by adding a few elements from inside
After Effects, starting with a simple shape layer in order to take
advantage of the brandnew Wiggle Transform operation in CS4.

11 SHAPE BUILDING
Deselect all, choose the Ellipse tool (nested under the Rectangle tool
Q), and create a small circle in the center of the screen. Move this
layer to begin at 1 second along the Timeline. Solo this element, and
let's modify it. Twirl down the Ellipse 1 property in the Timeline and
shut the Eye for the Gradient Fill. Twirl down Stroke 1. Use the
Eyedropper next to Color and sample one of the colors (bright green in
our example), and set the Stroke Width to 5 px. Name this layer
"Bubbles" and let's have some fun with it....

12 WIGGLE TRANSFORM
Select the Bubbles layer and in the Timeline choose Add>Repeater.
Twirl open Repeater 1 and change the Copies to 20. Then twirl open
Transform: Repeater 1; set the Position to 50, 0; and set the Scale to
80%. Now for the fun part from the same Add menu, choose the new Wiggle
Transform operator. Before we adjust it, drag Wiggle Transform 1 to
below Repeater 1 so it will wiggle all the repeater's copies
individually! Now twirl it open, set the Wiggles/Second to 0.5 and the
Correlation to 20%. Twirl down Transform, and change the values until
you're satisfied.

13 WIGGLE ADJUSTMENTS
In my comp, I've set the numbers pretty high so the circles are flying
all over the place, giving the illusion of fast, popping bubbles. Pay
attention to the fact that you must change the default values if you
want the Wiggle Transform to work well. Feel free to change the position
of the Bubbles layer until it looks the best overall, and change its
layer order as desired to integrate the bubbles better into the design.
Finally, set a global Scale animation to reveal the whole layer
(copyandpaste the Scale keyframes as we did in Step 6).

14 FINAL TOUCH
Let's add a small airplane to circle the art. Select the Text tool,
choose the Wingdings font in the Character panel, move to 1 second along
the Timeline, click in the comp, and press ShiftQ (PC: ShiftJ) for
the airplane symbol. Select the Text layer and create a circle mask
around the art with the Ellipse tool. In the text layer, twirl open Text
and then Path Options and set the Path to Mask 1 to align the airplane
to the circle path. Set Reverse Path to On and set keyframes for the
First Margin value at the start and end of this layer, adjusting them
until you're happy with the position and speed of the animation. Enjoy!
