Trang 8No lake so still but that it has its wave;
No circle so perfect but that it has its blur.
I would change things for you if I could;
As I can’t, you must take them as they are.
-Han Fei Tzu, noted Chinese Realist
Trang 10It was once said of science that the more we know, the less we know; or to quoteShakespeare, “There are more things in heaven and earth, Horatio, Than are dreamt
of in your philosophy.”
A rather strange statement indeed when applied to the subject matter of this book,
a software application called Adobe After Effects However, in the six years that I’vebeen using and teaching the application, this often describes the way I feel Becauseevery day I’m learning some new technique, some unique design concept, a differ-ent method of expressing a creative impulse, of communicating a point via ani-mated graphics
One can never know it all
At my seminars, I amuse the audience when someone raises a hand and asks, “CanAfter Effects do ?” and before they continue, I preempt the questioner by saying,
“Yes It can!” And that isn’t far from the truth, because almost any visual conceptyou can imagine can be implemented in After Effects
Go watch a major movie After Effects was probably used in the production Checkout TV commercials—more After Effects From something as subtle as changing thecolor of an actor’s hair to elaborately conceived spaceship battles in far-off galaxies;from creating animated graphics for display on a Web page to polishing up the latestentry to Sundance Power, flexibility, precision, grace After Effects exhibits all thesecharacteristics, and more
But what about the human element and the interface between imagination and
implementation? How do you get to that stage? How do you become expert (or
expert enough)? Some learn by example, others by rote Efficient learning, though,comes through comprehension and practice, then adaptation and improvement If
you see something, you’ll remember some of it, but if you see and do, your mind
and body develop a synergy of understanding
Which brings us to the ideal teaching process—this book Instruction and example
are all rolled up into the After Effects 5 Bible, which combines meticulous text with
practical examples provided on the DVD-ROM I consider this to be one of the bestAfter Effects books I’ve seen Why so, especially? Well, for me, it is J J and Zed’s
specific approach Just the right amount of instructional gravitas balanced with a
Trang 11gentle sense of humor Indeed, akin to a fine gourmet meal, let this reference cate and satisfy, until you, too, develop the means to express through art, with the
edu-After Effects 5 Bible providing your guidance.
Alan HamillDana Point, CAMarch 2002
Trang 12While it’s easy to learn, After Effects takes time and passion to master If an
artist has a real vision, passion for seeing that vision realized, and a mastery
of this fantastic tool, the final results will be gratifying indeed We’ve written the
After Effects 5 Bible with practical applications in mind Our primary focus has been
to provide you with a set of concrete steps for all the production scenarios you mightencounter When we were getting started in this field, we were confounded whenexperts would say something such as, “I did that with a displacement map.” Whileeveryone nodded in what appeared to our eyes as a somewhat unbelievable collec-
tive understanding, we’d be thinking, “Well, how exactly did you do that with a
dis-placement map?” Basically, we tried to write a book that we wished we had years ago.For most of us who use it regularly, After Effects is something of a religion It’s a joy
to use, and the people who make a living from it seem happy to while away entireportions of their lives manipulating the controls of its well-designed interface.Certain software applications develop an extremely devoted following, and AfterEffects is a prime example of this phenomenon More importantly, After Effectsdevotees form a community that’s mostly comprised of visual artists It’s so wellengineered that its audience can look past the vexing nature of computers andimmediately start throwing clay on the wheel Strength as a channel for creativity isits distinguishing trademark
After Effects has revolutionized the broadcast industry The mid-nineties showedthe public a dazzling array of visual artistry in ad campaigns and television networkpromotions, the quality and the quantity of which were unprecedented All corners
of the market have been dramatically affected On one hand, Academy award
win-ner John Gaeta, special effects supervisor for the immensely popular movie, The
Matrix, makes mention of his use of the application in a documentary about the
technical aspects of his work on that film On the other hand, wedding videoshave started appearing with suddenly high production values After Effects con-tributed to the rise of the so-called “digital video revolution,” and there arenumerous professionals whose careers stem completely from the widespread use
of this indispensable tool
So What Is After Effects, Anyway?
After Effects 5.5 is Adobe’s latest overhaul of this enormously successful motiongraphics software In years past, it has become a widely used tool in post-produc-tion, regardless of a facility’s size or budget Its use is prevalent at all levels of thefilm, broadcast, and Web industries, yet After Effects is noteworthy in that it is truly
software The application doesn’t rely on any proprietary hardware; instead, it
Trang 13requires only the inherent resources of a personal computer With the advent ofAfter Effects, the balance of power has shifted High-end studios with large quanti-ties of bulky and expensive analog equipment now share the market with talentedartists whose “studio” consists of a single machine Vital and important work is aslikely to originate from the realm of the desktop as it is from any other productionenvironment, and this is due in large part to the accessible power of this highlyuser-friendly application
Version 5.5 is a major upgrade, and the Adobe After Effects development team is to
be commended for their amazing work Truly phenomenal software, this build ofAfter Effects boasts a variety of new features as well as vast enhancements of itsuser interface There are numerous new filters for concretizing any effect that yourmind can envision Additionally, 5.5 includes native 3D-compositing capabilities aswell as vector paint tools, both of which were possible only a short time ago withthe purchase of expensive additional software Considering that the 3D toolsinclude lights, virtual cameras, and shadows, version 5.5 represents a huge leapforward for a product that had already filled its niche in the market
Every release of an Adobe graphics product allows for greater integration with theirother offerings, and After Effects is no exception After Effects 5.5 impressivelyimports work created in the latest builds of Premiere (6.0), Photoshop (6.0), andIllustrator (10.0) Real-time dynamic previews of compositions allow for instantvisual gratification as your work evolves over the course of a project Masks cannow be manipulated directly in the Comp window Multiple layers can be simultane-ously animated with the addition of a hierarchical parenting switch in the Timelinewindow The list goes on
Further still, Adobe has continued its efforts in bringing the power of procedural
animations to your work by adding something new called expressions Based on
JavaScript, expressions are scripts that you can use to dynamically control thevalues of different properties so that you don’t have to lose time setting tons ofkeyframes Finally, your output options have been greatly enhanced Compositionscan be rendered for the versatile Flash (SWF) file format just as easily as they can
be prepared with 16-bit color for HDTV or film
How This Book Is Organized
If you’ve read all the way up to this point, we’re hoping that you want to look intothis whole thing a bit further We’ve put this book together in an attempt to giveyou a complete tour of how After Effects works, as well as to describe some of theways you’ll actually use it in production We’ve also designed it so that it can beread from front to back or, if you prefer, as a desktop reference In either case,there’s some logic to the order of the chapters, and we talk a little bit about thatdevelopment in the following description of the book’s parts
Trang 14Part I: Welcome to After Effects 5
Part I acquaints you with the basics of the After Effects interface and gets youstarted on creating your own animations In essence, there’s an After Effects
“headspace,” or thought process, and the point of the first few chapters is to fullyintroduce you to this way of thinking Once you know the basics of importingelements and animating them, you will find it much easier to approach the moresophisticated aspects of compositing
Part II: Keyframes and Rendering
Part II looks into the different kinds of keyframe interpolation you can incorporateinto your animations Perhaps more importantly, this section of the book takes agood look at the Render Queue, that all-important “oven” where you bake yourcreations once you’ve thrown them together Lastly, this part of the book willintroduce you to the wonders of applying effects After all, the application is calledAfter Effects, and it hardly seems like fun to have to wait to see what the Big Fun isall about
Part III: Broadening Animation Skills: Masks, Transparency, and Time
Part III looks closely at the various ways you can work with transparency in AfterEffects Usually, budding motion graphic artists are too busy plotting the ways inwhich they might overthrow the industry before getting overly concerned withdetails such as alpha channels Nonetheless, an understanding of transparency isabsolutely critical to comprehending After Effects as a whole Even better than that,acquiring such an understanding is usually fun, at least when it’s compared to thekind of tooth pulling some folks imagine the topic to be Additionally, because AfterEffects deals with a succession of images over time, it’s also important to know how
to control the way time unfolds in your projects Do you want your clips to playslowly or quickly, or perhaps both at different points in their playback?
Part IV: Using Effects: The Big Fun
Part IV looks at the myriad of effects that you can apply to your moving images
Sometimes, this aspect of the application seems a bit overwhelming in light of thefact that the Production Bundle of After Effects now boasts of having more than 90plug-ins to enhance your work Still, the effects make up the reason why a goodnumber of After Effects aficionados initially sought out the software Perhaps yourhumble aim is to change the distribution of color in a clip of film that wasn’t litexactly right Maybe you happen to be interested in creating your own dramaticweather full of blizzards or lots of lightning Either way, the effects offer you themeans to make it happen
Trang 15Part V: Aiming Higher: Advanced Techniques
Part V goes into what some people think of as the “hard” stuff At this point, wecover topics such as Motion Math, expressions, 3D compositing, as well as trackingand stabilizing your footage We’ve also included a couple of chapters on the use oftext and typography, because so many folks who use After Effects initially come to
it from the need to make a title sequence
Part VI: Rendering for All Media
Part VI considers After Effects in the context of the greater realm of video production.What did you shoot on? What are you editing on? What’s your delivery format? How
do all the pieces fit together? This part of the book briefly touches on the role of AfterEffects in a production workflow that might run the gamut from miniDV to HDTV
Part VII: Appendixes
In the appendixes, we’ve given you a list of resources on the World Wide Web.These include sites that offer After Effects goodies that range from tutorials tostock footage to free plug-ins Additionally, we’ve given you a list of keyboard short-cuts for users of both the Macintosh and Windows platforms Lastly, we include anappendix that tells you what’s on the DVD-ROM in the sleeve on the back cover
How to Use This Book
It seems a little strange to have to explain how to use this book, but I guess someexplanation is needed (typically, when people ask us how to use a book, ourresponse is to politely tell them to read it) As we mentioned earlier, you can readthis book sequentially just as easily as you can jump from place to place whileusing it as a reference In each chapter, we did our best to debunk topics that mightappear complicated, and we also tried to give you a matching step-by-step exercise
to accompany each explanation
Conventions Used in This Book
We tried to keep the explanations from being overly technical in nature, butbecause we’re talking about software, sometimes there’s no way to avoid
digibabble Hopefully, the only parts of the book that will seem as though they’ve
been written in computerese are the keyboard shortcuts in the step exercises Just
so you know, whenever we refer to a keyboard shortcut, we first provide the Macinstructions, which are followed by a forward slash and the correspondingWindows instructions For example, the keyboard shortcut for Undo isCommand+Z/Ctrl+Z
Trang 16The DVD-ROM
Yep, it’s a DVD-ROM, not a CD-ROM All that means is that there is a lot more roomfor us to put stuff In other words, it holds more data than a CD-ROM, but it’s not aDVD that you can pop into the DVD player on your home entertainment system
Most computers sold in the past couple of years ship with DVD-enabled drives, soyou shouldn’t have any problems getting the data into your system
Throughout the chapters of the book, we consistently refer to the After Effectsprojects that we put on the DVD-ROM for you to refer to as you work your waythrough the step exercises If you want to get the most out of the lessons in thechapters, you’ll definitely want to copy the project files and their related mediaonto your own computer Of course, if you want to work with your own material,you’re welcome to do that instead
In addition to the projects and their media, we’ve also put a bunch of other goodies
on the disc, and we’ve given you a detailed listing of these in Appendix D
Icons and Sidebars
In a number of places, we found it useful to point out some important information
by highlighting it with these nifty little icons
Anywhere you see a Caution icon, just know that you might do some damage toyour project or your peace of mind
We used the Note icon to separate what we hope are useful bits of informationrelated to the topic under discussion
A Tip usually denotes a technique that saves a lot of time or is otherwise nently useful in production
immi-We placed Cross-Reference icons in spots where we mention a subject that iscovered in greater detail in another chapter We even go so far as to tell you thechapter number in the reference!
Lastly, we’ve included a number of sidebars devoted to the topic of what’s new inAfter Effects 5.5 They are sprinkled throughout the book wherever the update tothe application is relevant to the topic

Trang 17Contacting the Authors
Feel free to drop us a line at aebible@earthlink.net We’d be happy to hear any
insights and observations you might have While we read every message wereceive, just remember these two caveats: First, depending on the nature of ourschedule in addition to the volume of e-mail we receive, we may not be able to getback to every one of you Secondly, if you’re looking for any type of tech supportfor either your hardware or software, you should directly contact the vendor inquestion
So, get to it We sincerely hope that learning After Effects will be as much fun foryou as it was for us
Trang 18J J Marshall — Above all, I want to thank my wife, Christine If not for her continual
and unswerving support, this book wouldn’t even be a remote possibility For herlove, and the grace with which it is always and unconditionally given, I am profoundlygrateful
Even though he’s my coauthor, I feel it necessary to express my gratitude to Zed.Years ago, he took me to my first After Effects User Group meeting, and the rest, asthey say, is history More than that, I’m lucky to consider him a great friend It’s myhope that we continue our “vision quest” in one form or another
Much love and many thanks to the “folks” — my mother and father continue to serve
as the core members of a small, but devoted, fan club Everyone should be so lucky
If it weren’t for the support of friends like these, difficult deadlines would have beenimpenetrable walls Thanks to Eric Morrissey, Dan Sherman, Aaron Fein, Louie Berk,Mukesh Vasvani, and TJ Shea
Zed Saeed — It has been my privilege to be involved with the development of After
Effects for many years I have had the support and ear of many good people fromAdobe Systems: Steve Kilisky, Erica Schisler, David Trescot, Christie Evans, DanWilk, Richard Pelzar, Bruce Bowman, Kim Platt, Marcus Chang, Phil Nelson, andmany others have over the years put up with my nagging and harassment andresponded with nothing but kindness It seems like a foregone conclusion now, but Ihave long held that After Effects would take over the world, as it so rightfully has Special thanks to Showtime Channels and Sundance Channel for all the time theygranted me to be their After Effects artist, designer, and usurper of resources for all-night beta testing Thanks also to visionary art directors like Tony Castellanoand Crystal Hall-Aurnhammer, who spoiled me for anything else for the rest of myliving days
As always my gratitude goes to my mentor Dirk Van Dall, Vice President of DigitalVideo at Showtime Channels Dirk, an artist at heart and hands-down the mostknowledgeable person on digital media issues, got me started on this path and gave
me the access and direction to get where I am today As we like to say, “It’s Dirk’sworld We all just live in it.”
Trang 19The authors join together in expressing their gratitude to the following people.We’d like to express our appreciation to the people at Hungry Minds for all theirhelp preparing this book Thanks to Tom Heine, our acquisitions editor, forproviding steady support and looking out for us from the time the book was nomore than a concept
Also, many thanks are due to Melba Hopper, our project editor, whose tirelessefforts have resulted in making this book a reality Early in the process, she told usthat she didn’t like to work after 8 p.m., in the interest of preserving her sanity Wecould hardly disagree, but the number of late night e-mails we received from herwere a testament to her dedication We also want to express our gratitude to thecopy editor, Jerelind Charles, for her careful editor’s eye
We owe a great deal of credit to Adobe Systems, Inc — first, for creating and ing After Effects, thereby providing us with the opportunity to even write this book;second, and far more importantly, for continuing to develop After Effects as beauti-fully as they do Extra special thanks go to Steve Kilisky and Erica Schisler for theirkindness in finding the time to go out of their way to support us in the midst oftheir extremely hectic schedules
releas-We particularly want to express our appreciation for the work of Alan Hamill, ourtechnical editor It’s a privilege to write about After Effects when you know that amember of Adobe’s superb digital video team is watching out for you
A number of companies kindly provided us with some gorgeous stock footage Wedeeply appreciate the contributions made by John Davis from bestshot.com; SamBartlett from Digital Juice, Inc.; Steve Gianfermo from Videometry; Charlie Pattonfrom EyeWire by Getty Images; Dave Hill from Creatas; Barry Dagestino, MichaelPixley, and Domenic Rom from Sekani; and Julie Hill from ArtBeats If you needproduction-quality elements, look these guys up
Thanks to Victoria Hamilton from The Foundry in the U.K They make fantasticplug-ins, and Vikki is a highly valued ally
As we began putting this book together, many colleagues graciously answered thecall to contribute some of their work to the cause For this, we deeply thank AdamHelfet Hilliker of HelfetHillikerGormley Designs (say that 10 times!), Steve Fein of BigRipple Multimedia, Axel Baumann, and Mark Magnus All of them are great artists
As some of you may know, there are a number of very talented folks who preparetop-notch training materials for After Effects Brian Maffitt and Trish and ChrisMeyer have set the bar in this particular field We owe them our thanks for theirinspiration and our respect for their contributions
Trang 20Last, but certainly not least, everything changed one morning during the secondweek of writing this book The atrocity of September 11 hit so close that it literallyshook the windows of our homes We were spared, but thousands were not Writingabout After Effects suddenly seemed frivolous when compared to the harrowingreality that too many of our neighbors had to face Our hearts go out to those whowere lost and to those who lost them on that day Despite its wounded soul, NewYork City is still a great place to live, and we do so with pride.

Trang 36Making a Movie with After
Effects
Greetings, folks! Welcome to the amazing creation known
as After Effects If you’ve never used it before, then thisQuick Start chapter will introduce you to the basic workings
of the application If you’re a graphics professional, you mayhave worked with some of Adobe’s excellent contributions tothe field, and After Effects deserves its place in the company
of great programs like Illustrator and Photoshop Othersamong you may be getting more deeply immersed in therapidly expanding world of digital video and are wonderingwhat the hype surrounding After Effects is all about Nomatter how you ended up here, there’s no question that theapplication can take your dynamic media productions to ahigher level By the time you’re finished with this brief chap-ter, you’ll be familiar with its basic animation techniques and
be able to create your own QuickTime movie as the result ofyour efforts
This chapter assumes that you’ve pulled up a chair next toyour happily humming workstation and want to get down towork Armed with a copy of After Effects and this Bible, it’stime to see what a few clicks of the mouse will yield Getting
up and running involves familiarizing yourself with some mentary compositing techniques If you aren’t clear as to
rudi-exactly what it is, After Effects is visual effects and
composit-ing software that gives you tight control over your motiongraphics productions For the most part, that means that youcan use it to make preexisting elements move through spaceover time while directly controlling their appearance You’ll
be able to see this for yourself very quickly
Trang 37Adobe Systems, Inc., has recently unleashed version 5.5 of After Effects upon theworld This means a number of things, such as support for Mac OS X, enhanced 3Dcontrols, new effects, smart mask interpolation, and a whole host of enhancementsand goodies Version 5.0 was a quantum leap in and of itself, introducing 3D anima-tion into what had always been a 2D environment, as well as offering the controlafforded by expressions, which are based on JavaScript These are great develop-ments, and by the time you make your way through this book, you’ll know a gooddeal more about them than you do now If you’re new to this corner of the universe,don’t worry We’ll tell you what all these things mean a bit later For the moment, youshould focus your attention on the basics of this program that have made it such apowerful tool from the very beginning.
The Quick Start “chapter” is our introduction to new users of After Effects If you’re
an After Effects veteran, you probably don’t have much to gain from the followingexercises If that’s the case, you may want to use the book as a desktop reference
We leave it up to you
Building an After Effects Project
Without any more drum rolls, go ahead and fire up your machine and start AfterEffects by double-clicking its application icon When you open up the program forthe first time, you are greeted with the splash screen while the application loads,and then you see an empty Project window and some palettes Before you getoverly concerned with exactly what these are, start building good habits by savingyour project
In order for these opening exercises to work properly, you need to copy the Source
Material folder from the DVD-ROM to your hard drive Over the course of theQuick Start chapter, you’ll be working with a number of files that we put in thisfolder We provide you with a QuickTime movie that we rendered from our own
project using the same elements The movie is called QS Rendered.mov, and we
suggest that you look at it to get a sense of the composition you’ll be building.Also, if you want to look at the finished version of the After Effects project that
you’re going to create in this chapter, take a look at the one called Quick Start.aep You can find both the finished project file and the QuickTime movie in the Project
Files/Quick Startfolder If you want to get the most out of the chapter, you maynot want to open the finished After Effects project until you’ve tried to completethe project on your own
Saving a project
After you initially open the application, by default, After Effects creates a project
called Untitled Project.aep Change that and give this project a name Choose
On the DVD-ROM Note
Trang 38File➪ Save As and the Save Project As dialog box opens up Name the file
some-thing such as My Quick Start project.aep and save it in a location where you plan on
saving your After Effects work
You should make a habit of keeping the aep file extension on the tail-end of allyour After Effects project files There are a couple of good reasons for this First ofall, if you’re working on a Windows-based PC, your system may not recognize thefile without the correct extension Secondly, if you’re working on a Mac, while itdoesn’t matter because the OS will recognize the file whether or not you add theextension, if you ever want to bring your project into a PC environment, the aepfile extension will suddenly become an issue In short, we recommend that youget in the habit of ending your project filenames with aep See Figure QS-1
Figure QS-1: An After Effects project file uses the aep
extension and contains links to various media, not the actualmedia
After Effects project files are interesting animals, because they don’t contain anyactual media If you’re a video editor, you’re used to this concept because video-editing applications work in a similar fashion This may not seem overly remarkablewhen you first think about it, but we should mention that most other programshandle the job of saving their respective files somewhat differently For example,when you save a Photoshop or word-processor file, you’re writing the contents ofthat file to disk When you save an After Effects project, you’re saving a file thatcontains links to the media that are used by the project, not the actual media itself
For example, imagine that you’ve brought a QuickTime movie into your AfterEffects project After you save the project file, if for some reason it is inadvertentlydeleted, the QuickTime movie won’t be lost What’s lost is the project file contain-ing the link to the QuickTime movie This will make more sense as you movethrough the chapter, but that’s the basic idea behind the actual contents of anAfter Effects project file
STEPS: Bringing Elements into Your Project
1 Choose File ➪ Import ➪ Multiple Files This opens up the Import Multiple
Files dialog box shown in Figure QS-2
Caution
Trang 39Figure QS-2: Choose File➪ Import ➪ Multiple Files
to open the Import Multiple Files dialog box
2 Navigate your way to the location where you copied the files from the
DVD-ROM to your hard drive and select the Quick Start Media folder by
5 In the Project window, twirl open the Quick Start Media folder by clicking
the small triangle to the left of it Doing this displays the contents of the
folder you just imported
Okay, mission accomplished You successfully brought in all the media you’re going
to use to create your animation
Select any of the footage items under the Quick Start Media folder by clicking them
once, and a thumbnail sketch of the item appears at the top of the Project window,along with some information describing the file’s vital statistics Look at Figure QS-3
to see what After Effects has to say about some of the media you imported
You may have noticed the asterisk following your project name at the top of theProject window This is After Effects’ way of telling you that your file has been modi-fied since the last time you saved it Because you just imported all that media, youshould save your project As a general rule, anytime you make significant changes
to your project file, you should save them Go ahead and choose File➪ Save and do
it regularly in the future You’ll be glad you did
Trang 40Figure QS-3: If you click a footage item in the Project window,
After Effects will show you a thumbnail of the file and tell you everything it knows about it
If you remember what we told you earlier, then you’ll know that your project filenow contains links to the media you just imported This is an important detail, andwe’ll explain why If you were to quit After Effects and move any of the media filesyou just imported to a different location on your hard drive, the next time youopened up the project, After Effects would report the moved files as missing Later
on in the book, we explain how to relink your project to files that have beenmoved, but at this point, you should at least be aware of the fact that movingmedia around the different folders of your hard drive can result in problems
Caution
