Of all the effects and motion graphics software on the market today, After Effects is arguably the most popular. Developed by CoSA, purchased by Aldus, and acquired by Adobe Systems in 1994, After Effects boasts an installed user base of more than 100,000. Most visual-effects fa cilities both large and small rely on the software's compositing, animation, and effects features on a daily basis.
One of the reasons that After Effects has enjoyed such widespread adoption is its comprehensive suite of core tools that meets the needs of most Mac- and Win dows-based 2D and 3D visual-effects artists designing for film, video, multimedia, and the Web. Another reason is that over the years, a large and varied selection of third-party plug-ins has been developed for use with the program.
"We've been using After Effects plug-ins since they first became available," says Mike Goedecke, lead creative and partner at Belief (Santa Monica, CA), a creative content studio specializing in broadcast design and live action. "We use plug-ins every day, in all our projects, because they help us give a distinctive visual style to our work. There's such a variety of them available that there's almost no limit to what you can do inside After Effects."
According to After Effects senior product manager Steve Kilisky, more than 20 vendors are shipping close to four dozen After Effects plug-in packages; most comprise numerous individual plug-ins (also called filters), making the total number of plug-ins difficult to count. All of them en able users to automate or customize their workflow, add professional effects to their projects, or simply work more efficiently.
According to Kilisky, so many plug-ins are available for After Effects because the software-like Adobe's other products, including Premiere, Photoshop, and Illustrator-is designed to be extensible. "Our philosophy is to think of After Effects as a compositing environment that we've opened up to third-party developers who can add on to that environment as customers' needs change," he says. "In some cases, we don't have the expertise in-house to incorporate into After Effects all the features that our customers tell us they want. So instead, with each release of After Effects, we open that environment even further to allow third parties to write plug-ins that add the functionality our customers are asking for."
Early versions of After Effects featured an Effects API (application programming interface) that enabled third-party developers to write plug-ins designed to extend the software's compositing, animation, and effects capabilities. These early versions of After Effects also featured Ado be's Bottle neck API, which developers could employ to write plug-ins that allowed a user's hardware to accelerate basic geometrics and layer management.
Third-party packages that made use of these APIs began shipping in 1996. The first was designed for use with After Effects 3.0. Called KPT Final Effects and developed by UDAC Multimedia, the plug-ins in this package enabled users to create animated simulations of shattered glass, smoke, fire, and explosions as well as particle systems, directly from within After Effects.
Throughout the After Effects 3.X time frame, several additional popular third-party packages began shipping. Ali en Skin released Eye Candy, a set of 20 special-effects plug-ins. Boris Effects started shipping Boris AE, a set of production-oriented plug-ins designed to provide faster blurs and true optical color correction, among other capabilities. And DigiEffects began offering a series of plug-in packages including Aurorix, which provides users with the AgedFilm plug-in, along with more than two dozen natural and organic effects.
With After Effects 4.0, which began shipping in January 1998, Adobe added an External Monitor Preview API with which developers could write plug-ins that allowed a user's hardware to send the contents of the After Effects Composition window to their video output(s).
With Release 4.1 of After Effects in 1999, Adobe further extended the software's API architecture. That extension came primarily in the form of the After Effects General Plug-In (AEGP), which gave third parties access to more After Effects project data, including keyframes and layer sequences. This enabled software developers and nonlinear and other video-editing manufacturers to write new plug-ins that would enable video-editing users to import their projects directly into After Effects. The AEGP API also provided more extensive support for hardware acceleration, and it exposed new 3D channel information for third-party development.
One of the first video-editing vendors to make use of these additions and enhancements was Media 100, which developed a plug-in that enables users to import their Media 100 projects into After Effects, rather than having to jump back and forth between the two systems.
In addition, Integrated Computing Engines (ICE) developed a hardware/software solution to accelerate both After Effects 4.1 and systems from Avid. Now available through Media 100, the basic ICE hardware consists of four processors that accelerate preview and rendering of Media 100's iceFX After Effects plug-ins, as well as the performance of core After Effects functions such as motion blur.
Other notable plug-in packages that take advantage of the API additions and enhancements made during the After Effects 4.X timeframe include The Foundry's Tinderbox image processing plug-ins, Atomic Power's Psunami water plug-in, Zaxwerks' 3D Invigorator for producing broadcast- and film-quality 3D graphics, and Maya Paint Effects, which brings Alias|Wavefront's 3D paint technology to After Effects users.
With After Effects 5.0, which shipped this spring, "We have enhanced the AEGP API to allow third parties to develop plug-ins that control every project element, from footage to individual keyframes, for applications such as motion tracking," says Kilisky. "And we've added the Artisans API, which is based on the AEGP API and allows third parties to, for instance, write raytracing or radiosity renderers for After Effects."
The AEGP API has also been augmented to allow enhanced support for video-editing systems. Already, Automatic Duck has developed a plug-in based on these enhancements. Called Automatic Composi tion Import, the plug-in uses new extensions in the AEGP API to streamline the process of importing projects into After Effects from Avid nonlinear editing systems.
Another company taking advantage of the AEGP API is Synthetic Aperture. "With our Echo Fire plug-in, we've been offering users real-time video previews in After Effects," says the company's owner, Bob Currier. "But with the new AEGP API in After Effects 5.0, we can add real-time audio capability. This gives users a great way to check sync between audio and video."
In addition to the AEGP API, Adobe has enhanced the software's Effects API to support 16-bit-per-channel color. Both RE: Vis ion Effects and The Foundry have rewritten their offerings, which originally supported 8-bit color, to take advantage of Version 5.0's support for 16-bit color.
The combination of After Effects' extensible architecture and Adobe's pro-developer attitude has contributed to the program's popularity among plug-in developers. "Of all the similar packages out there, After Effects has the richest API, and Adobe gives you access to virtually all of it," says Synthetic Aperture's Currier.
Pete Litwinowicz, president of RE:Vis ion Effects, agrees. "If you want to develop a plug-in, you can get what you need from an SDK [software development kit] that you can download right from the Adobe Web site. You don't need permission from Adobe to write a plug-in."
According to Adobe's Kilisky, third-party plug-ins have been an integral part of the success of After Effects. "We're very fortunate to have passionate third-party developers who create lots of added functionality for After Effects," he says. "Yes, After Effects does what it's supposed to do, and does it really well, but there's still a lot more that can be done on top of that."
