We've never had such a wide range of powerful graphics programs, yet it can still take hours to create common effects. particleIllusion takes all the hassle out of producing amazing effects such as explosions, smoke, fire, sparkles, motion graphics backgrounds, space effects, creatures, and abstract artistic effects.
The latest version of the Mac OS X app, particleIllusion 3.0.5, promises to operate 10 to 20 percent quicker than the previous release and comes with a dazzling array of different preset effects. Since particleIllusion is a standalone application, you can use it with any video editing or compositing software. You can bring your movies or image sequences into particleIllusion, add the particle effects you want, then save the output movie or image sequence.
