Animated swirls are all the rage in the motion graphics world, and there are some pretty cool things that can be done with them. But creating and animating such elements is really not as difficult and time-consuming as it would seem, even if the shapes are detailed and intricate. Bring on the swirls!

1 CREATE ILLUSTRATOR SWIRL
Let’s start out in Adobe Illustrator CS3, by far the best tool for creating such design elements—and as you’ll see, hugely important in providing the actual animation paths for us also (yes, you read that right!). Create a new document called “Swirls” at 720×540 pixels, and set the Color Mode to RGB. Click OK, then using the Pen tool, create the main stem for the left side of your design. Then switch to the Spiral tool to draw the swirl on the right. With the Direct Selection tool, select the right end point of the Pen tool path and the left end point of the swirl path and go to Object>Path>Join to create a single path.

2 ADJUST FILL; ADD LAYER & STROKE
With the path selected, go to either the Toolbox or Color panel, click the Fill icon then the None icon to remove the default white fill, leaving only the black 1-point stroke (going to View>Show Transparency Grid can help confirm this is done). In the Layers panel, double-click Layer 1, rename it “Stem,” and click OK. Then click the Create New Layer icon, rename the new layer “Branch 1,” and use the Spiral tool to draw another swirl coming out from the stem, as shown above.

3 ADD LAYERS & STROKES
Continue the same steps (new layer, draw new branch swirl, check fill is None) for as many branches you would like to have coming from the main stem. Make sure the branches start at the stem as accurately as possible. (Note: To draw a swirl in the opposite direction, click once on the artboard with the Spiral tool and select the other Style in the Spiral dialog.) In this case, I’ve created a total of four extra branches. Save your document as Swirls.ai at this point, then go to Window>Brush Libraries>Default Brushes, and choose Basic RGB.

4 ADD BRUSH STROKE; ADJUST WIDTH
With the Selection tool, select all of the stem and branch elements, and click on the second brush graphic in the Basic RGB panel to apply that style. Feel free to use any of the other Brush Libraries, or indeed create your own, to suit your taste. In the Stroke panel, adjust the Stroke Weight accordingly to achieve the desired effect (1.5 pt in this example). Save the file once more, then switch to After Effects.

5 CREATE MASTER COMP; IMPORT SWIRLS
Click the Create a New Composition icon at the bottom of the Project panel, name it “Little Swirls,” and set it to NTSC D1 Square Pixel (720×540) for consistency. Set the length to 8 seconds or so, and click OK. Now, double-click in the Project panel to bring up the Import File dialog, locate Swirls.ai, choose Import As Composition – Cropped Layers, and click Open. Double-click the new Swirls comp in the Project panel to open it. Go to Composition>Background Color and choose white so you can see the swirl elements.

6 EDIT ORIGINAL IN ILLUSTRATOR
Believe it or not, you’ve done the hardest part of the project, and have also unknowingly created the animation paths that will “reveal” the strokes perfectly. Select the main Stem layer in the Timeline, then press Command-E (PC: Ctrl-E) to Edit Original back in Illustrator. Once in the program, go to View>Outline—this is how we want After Effects to see our path shape, as we’re going to copy and paste it. Due to the fact we have a custom brush applied, however, this will most likely not work. So…

7 REMOVE STROKES; COPY & PASTE
Press Command-A (PC: Ctrl-A) to Select All of the lines, go to the Color panel, click the Stroke icon, and click the None icon to remove the brush stroke. As long as we don’t save this document, our brush strokes won’t be affected. Now target just the Stem layer, and press Command-C (PC: Ctrl-C) to Copy the path into memory. Switch back to AE, and with the Stem layer still selected, press Command-V (PC: Ctrl-V) to Paste the path as a mask shape onto the layer. Double-click on the right side of the path in the Composition panel and drag to align with the brush stroke. Press Enter when you’re done.

8 REPEAT PROCESS(ES)
Now switch back to Illustrator and do the same process for the remaining strokes: Target one of the paths in the Layers panel, copy it, switch to After Effects, select the corresponding layer, paste the path as a mask, then nudge it into position if necessary. When all the paths have been copied and pasted, switch back to Illustrator, close the file, and do not save the changes.

9 ADD STROKE EFFECT; ADJUST
Starting with the stem now, we can create one animation technique that can be re-used on all the other layers. Select the Stem layer and go to Effect>Generate>Stroke; a white stroke will appear on the layer. In the Effect Controls panel (ECP), you’ll see that Mask 1 is selected as the path being stroked. Adjust the Brush Size and Brush Hardness until the original black line is hidden; in my case, a 6-pixel stroke and 100% hardness cover it just fine.

10 ANIMATE STROKE
Now drag on the End value and you’ll see your stem drawing perfectly back and forth. See, I told you it was easy, didn’t I? All you need to do now is animate the End value across time. At 0 seconds, click the Stopwatch to set a keyframe for the End value at 0%, move along the Timeline to 2 seconds, and set the End value to 100%. Then Control-click (PC: Right-click) the second keyframe and choose Keyframe Assistant>Easy Ease In. You’ll notice the line is actually erasing itself at this point, but that will change in the next step. Note: Depending on how you created the shape, you may need to animate the Start point instead.

11 SET MASK
Very cool indeed! There’s one more step, however. If you go to Composition>Background Color and set the color to a blue, you can see all we are doing is using a white stroke to hide/reveal a black stroke—which is no good if you intend to composite these swirls on a different background. Back in the ECP, simply set the Paint Style to Reveal Original Image—perfect! You’re animation should now be drawing the line instead of erasing it, as well.

12 COPY & PASTE EFFECT; ADJUST TIMING
Now the same Stroke effect, including keyframes, can be re-used for the branches. In the ECP, select the Stroke effect name at the top and Copy it. At 0 seconds in the Timeline, select the branch layers and Paste. Now, simply click-and-drag the keyframes in the Timeline to adjust the timing for each branch so that they start to reveal just after the stem has passed by, and your swirl animation is complete!

13 COMPOSITE BACKGROUND; CHANGE COLOR
Now switch to the initial Composition you created in Step 5. Import a textured background image, such as this one from iStockphoto.com (#3855804), drag it into the Timeline at 0 seconds, and scale accordingly. Then drag your animated Swirls composition over the top, and duplicate, scale, position and rotate accordingly. Now, go to Effect>Generate>Fill, change the color to white, and set the layer Blend Mode in the Timeline to Overlay. Repeat this step for each of the Swirls comp layers in the Timeline.

14 ADJUSTMENT LAYER; GLOW
At 0 seconds, go to Layer>New>Adjustment Layer, then Effect>Color Correction>Tritone. In the ECP, change the Highlights swatch to a slight off-white, and the Midtones swatch to orange. Now choose Effect>Stylize>Glow, and set the Glow Threshold to 100% (experiment with the settings based on the background you’re using). Hit 0 on the keypad for a final RAM Preview, and your simple, single-line vector swirls from Illustrator look completely different now, not to mention that their own paths essentially self-animated! Use them creatively. Enjoy!

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.

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 square-pixel comp of 720×534 pixels (from the Preset drop-down 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. Double-click the imported comp (ours is “Flower Power”) to open it, ensure nothing is selected, and then double-click 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 Shift-Command- (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 Shift-select both keyframes for the Scale property. Copy them to memory (Command-C PC: Ctrl-C). Now, select the rest of the layers in the comp (excluding the Background and the layer you’re copying from), and Paste (Command-V PC: Ctrl-V) to apply the same animation to all of them. “Un-Solo” 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: Right-click) 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 bottom-left 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 brand-new 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 (copy-and-paste 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 Shift-Q (PC: Shift-J) 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!

Typography is one of the qualities upon which we base most of our design work, and the type animation engine in After Effects offers a gamut of ways to express typographic flair. One of my favorites is the ability to control the 3D motion and position of text characters. When combined with simple camera moves, depth of field, and some real-world studio tricks we use every day, the results can be—literally—powerful. Let’s get started.
1 CREATE PROJECT; ADD BACKGROUND, TYPE
Create a New Composition, named “Power of Words,” at HDTV 1280×720 resolution with a 6-second duration, and then double-click the Project panel to import an image to use as a background. For this example, I purchased a vector illustration of blurry lights (#4292586 from www.istockphoto.com). Drag the image into the Timeline at 0 seconds and use any effects to adjust color or contrast, as well as an Effect>Blur & Sharpen>Fast Blur to soften focus. Go to Layer>New>Text, and enter the main text. We’ve styled ours using Helvetica Neue (85 Heavy and 35 Thin), 30-px size, Optical kerning, Tracking 10, black, and centered.

2 ADD AND EDIT 3D CAMERA
Now, go to Layer>New>Camera, choose 15mm from the Preset drop-down menu in the dialog, and click OK (if you get a 2D warning dialog, just ignore it for now). Press P on your keyboard to reveal the camera’s Position properties, and adjust the Z position value to –600 for the time being. Now go to Layer>Transform>Auto-Orient, choose Off, and click OK.

3 ADJUST 3D POSITIONS
Click the 3D Layer switch next to both the text and background image layers in the Timeline, then select the background image layer, hit P, and set the Z position to 3000 in the far distance. Now, press Shift-S to show the Scale property also, and scale the background image until it touches the edges of the full composition.

4 DUPLICATE AND ADJUST TEXT
Twirl up the background image layer’s properties, select the text layer, and press Command-D (PC: Ctrl-D) to duplicate it. Click the Solo box on the left of the Timeline for that layer and in the Character panel, change its color to white. (Note: Go to Composition>Background Color and change the color to black so you can see your white text.) Now, change the Font family to be the same throughout—in this case Helvetica Neue 45 Light, the Size to 24 px, and the Tracking to 100.

5 EDIT TEXT; RENAME LAYER
Now, double-click the T icon next to the layer’s name, then type in a series of words or sentences of your choice. The longer the line, the better the finished 3D strings of text will be, so feel free to type and copy-and-paste to extend the lines. You’ll notice that the layer’s name becomes rather awkward to work with, so when finished, click on the name of the layer, press Return (PC: Enter), and rename it to “Long line of type” or something short to that effect.

6 ADD FIRST TEXT ANIMATOR
Now for the animators! Twirl down the Long line of type layer, twirl down Text, then click the arrow to the right of the word “Animate” and choose Anchor Point to add your first Animator. Click on the name of the Animator, press Return (PC: Enter), and rename it “Animator 1 – Anchor Point” for easy recognition. Go back to Animate and choose Enable Per-Character 3D from the menu, then adjust the Anchor Point Animator’s Y value to sit in the vertical middle of the type—in our example, around –9. This enables rotators we add later to spin from the center of the letters, not their baseline.

7 ADD SECOND TEXT ANIMATOR
Twirl up and deselect Animator 1, then go back to the Animate menu and choose Position, which adds a second animator. Rename it “Animator 2 – Position Wiggle,” then next to the new name, click Add and choose Selector>Wiggly. This is where the fun and creativity really begin!

8 ADJUST POSITION AND WIGGLE VALUES
In the Position value within the animator, adjust the XYZ values to 400, 600, 400, respectively. As you can see, this blows the characters far apart easily. And if you scrub the Timeline, it looks crazy too—but this is easy to control. Twirl down Wiggly Selector 1, set the Wiggles/Second to 0.05 (it will show 0.1 when you press Return [PC: Enter]), and most importantly, set the Correlation to 96%. This causes the letters to remain more in line with each other, forming a gently rippling line of type.

9 ADD THIRD TEXT ANIMATOR
Deselect all, go back to the Animate menu, select Rotation, and next to the new animator, click Add and choose Selector>Wiggly. Rename this animator “Animator 3 – Rotation Wiggle,” then adjust the X, Y, and Z Rotation selectors to 1x, 2x, 1x, respectively. Now twirl down Wiggly Selector 1 and adjust the Wiggles/Second to 0.35 and the Correlation to 0%, and scrub the Timeline. This correlation value allows the random rotation to apply to the characters individually, which looks very cool.

10 ADD FINAL ANIMATOR
Deselect all, go back to the Animate menu, choose Character Offset, and then add a Wiggly Selector into that new animator. Rename this animator “Animator 4 – Character Offset,” then go to the newly added Character Offset value and set it to 10, and the Character Alignment to Center. Now adjust its Wiggles/Second to 2 and its Correlation to 0%, then view the results. Looking pretty cool!

11 ADD RANDOM LAYER ORIENTATION
Now to adjust the entire layer’s rotation in anticipation of the next step, twirl up the entire text layer, then hit R to reveal its Rotation property. Hold down Option (PC: Alt), click on the Stopwatch for X Rotation to add an expression field, and type in wiggle(0,180), then hit Enter to confirm. This will randomly rotate the layer up to 180° on the x-axis, but with no motion. Now repeat this process to add expressions to both the y- and z-axes, using wiggle(0,360) and wiggle(0,180), respectively.

12 DUPLICATE, DUPLICATE, DUPLICATE
Everything we’ve created so far is referencing Wiggle values, which are created randomly in After Effects on a layer-by-layer basis, so if we duplicate this layer, we’ll get wildly different results. Twirl up the text layer, select it, then press Command-D (PC: Ctrl-D) to duplicate it. Not only do you see a new spread of text characters in completely different positions, but the layer name has added “2” to the end, which is why we renamed it. Now, duplicate as many times as you like to suit your design.

13 ADJUST AND ANIMATE CAMERA
Turn off the Solo icon for all of the type layers, then select the Camera 1 layer and change its Z Position value to –900. At 00:00 seconds, click the Position Stopwatch to add a keyframe, then scrub to 04:00 seconds and change the Z position value to –300. Select that second keyframe and go to Animation>Keyframe Assistant>Easy Ease In (PC: Shift-F9), or adjust the velocity to suit your own design.

14 ADD DEPTH OF FIELD; MOTION BLUR
Finally, press AA to reveal the Camera Options, then turn Depth of Field to On. Change the Focus Distance to 300 and the Aperture to 80 pixels—this gives us perfect focus on the final wording line at 04:00. Feel free to turn on the Motion Blur switch for all of the text layers, then render your final movie.
A really powerful, and even slightly disturbing, motion piece created easily and quickly thanks to some careful planning, animators, wigglers, and expressions, and of course some good “Energi.” Enjoy!

How about a fun effect for your incredibly boring photo albums? Creating a old comic book effect for your photos is easy and the results are visually appealing. More fun is achieved when adding captions to your photos using comic book fonts and design elements.
This tutorial will show you how to give a comic book look to your photos using a couple of filters and some additional decorations.

Click on the image below to see a larger and more clear image of the final results.

Old halftone print effect

Download and open this photo in Photoshop. Now we are going to increase the overall contrast of the picture by burning it a bit. Go to IMAGE > ADJUSTMENTS > LEVELS…With this image we are going to set the INPUT LEVELS to 60 / 1.00 / 220. But this is only for this example. Choose the best settings for each photo.

In this step we are going to give the photo an illustrated look with some graininess to give the illusion of an old and bad quality paper. It is not a realistic effect, it is just some distortion to the image to help us achieve the final look. Go to FILTERS > ARTISTIC > FILM GRAIN. In this case we are going to use: GRAIN: 4, HIGHLIGHT AREA: 0, INTENSITY: 10. Try different settings for different photos.


In this step we are going apply a halftone pattern to the image to give the final old comic book printing effect. Go to FILTER > PIXELATE > COLOR HALFTONE. Set MAX RADIUS: 4 and leave the rest with the default values. Press OK and then go to the LAYERS PALETTE and set the BLENDING MODE to DARKEN.

Adding comic book elements to the picture

The effect looks nice so far. It is not a realistic old comic book effect, it simple resembles that look. To make it more real, now comes the fun part. We are going to add some unique elements that are very popular on comic books and strips
Select the HALFTONE layer and set a STROKE LAYER STYLE of WIDTH: 20px, POSITION: Inside and COLOR: #F5ECE1.

Add a new layer and draw a small rectangle at the top left of the frame of the image. Give it a STROKE of 3 pixels and paint it orange. An orange to yellow gradient looks better. Draw another rectangle, a bit larger this time, on the lower left corner of the frame. Give it a STROKE of 3 pixels and paint it white. The final result should be like the one below:

Lets add a border to the image: Add a new empty layer above the layer containing the rectangles we created in the previous step. Select the RECTANGLE SELECTION TOOL from the TOOLS PALETTE. Draw a selection from the top left (right inside the frame) to the bottom right border of the image.

Go to EDIT > STROKE, set WIDTH: 4px, COLOR: BLACK, LOCATION CENTER and press OK.
DESELECT the current selection and go to FILTER > BLUR > BLUR MORE. Then apply a small distortion using FILTER > DISTORT > RIPPLE… (Amount 20%, Size Medium). Now, lets sharpen the stroke a bit with FILTER > SHARPEN MORE and there you have a nice simulated hand drawn border.

Adding captions using a comic book font

To add captions to the photo you can use any font you like, but only using fonts specially designed for comic books you will be able to achieve the desired look. Download the free font Digital Strip and install it. At the end of this article you will find a lot of free and commercial comic book fonts and resources.
Using the Digital Strip font you’ve just downloaded, type a date on the top orange rectangle. Play with the first letter of the text by adding a stroke, a shadow and a bright contrasting color.
Then write a caption for the photo at the bottom white rectangle. Highlighting some words in bold also looks good.
And that’s all. Your image should look similar to the one below:

Adding other comic book elements to your photos

If you want to learn more about comic book design, you can browse sites like Comic Book Fonts or Balloon Tales for some inspiration. Balloon Tales has published a fantastic comic book lettering tutorial that you should read if you want to make some stunning sound effects. There are lots of comic book resources, but these two are very colorful and loaded with design tips and examples.
As an example, I’ve created two images using other design elements such as balloons and sound effects:
