I used keyframes in the paseq timeline. and i varied the values of certain parameters over time. Settings like path length, color and some path load settings changed value over time. The path "fade out" near the end was…"
Animation mostly; some graphics; photography. Motifs from hyper-realistic to abstract. I use SA's rotoscoping/auto-drawing features and its "old school" manual hand drawing capabilities. I use MSG Evolver on its own and in Studio Artist paint action sequences.
Digital media with analog heart.
Doing digital monk's work; I labor (enjoyably) to create a swirl of film, video and enriched digital paint. My roots are in experimental film, hand rotoscoped animation, audio collage, stereoscopic & hand colored photography.
I've done work for narrative, documentary, music video, dance, theater, corporate and private projects, including the BBC mini series, "Gory Greek Gods". Screenings in Atlanta, Berkeley, Boulder, Dallas, Los Angeles, New York, Miami, Philadelphia, San Francisco, Seattle and Zagreb.
New areas of development include work for dance, theater and opera.
I really admire you're work and was wondering if you could provide some insight into your World Trade Center video on your site. I imagine it was done with time particles but I can't quite get mine to behave the way I want to. I've read your responses in other forums of how your animations require very careful tweaking and maybe that's what I'm getting wrong but I would really appreciate a helpful hint.
i'm gla di could help. but since I mistakenly posted my reponse on your comments page... i've reposted it here for others to see:

You are right about the "tweak" issues. Because with the time dependent nature of Time Particles you can have the same settings work on one video clip and fail on another. For instance with the WTC clip I have the particles following paths of luminance. So light areas in the source image steer the particles in one direction, dark areas in the other. This makes things very sensitive to the brightness and contrast of your source.
For your purposes, I'm guessing that most important settings contributing to the World Trade center piece are:
That the particles follow lines of luminance:
TP2>Path Angle: Lum
That the particles only live for a while:
TP1> Fixed Time=60 (I'm guessing here... I don't have the original paseq anymore)
And that I do not erase the canvas, but fade the canvas to black to increase continuity:
Image Operation> Fixed Color >Black >Mix:(approx)15%
This causes the particles which have been painted on the canvas to fade to black over time... in effect a 15% black eraser which slowly removes what's old on the canvas. This is a classic approach; leaving trails, creating some continuity from frame to frame and adding to an overall sense of smoothness.
Other than that, play with the number of paths, the size of the brush, the spacing of the particles... and do your development and tests on the very clip you intend to use...because too many things change from video to video. Keep "exporting as" all your test paseq's so you have all your incarnations in case you need em. And when you have something you like, use that paseq as your starting point to tweak for other source video. There's a good chance you'll go through 10-20 different versions before you find the one that works just right for you.
Simple vector font paint synthesizer preset with some added cast shadow lighting via a PASeq cast shadow lighting preset. I had the Source area set to Palette with the Random option, so that the coloring is a random choice from the source color…

"Yes, sure, I know, but , for example, how can I have more bigger fonts ? I posted yesterday a picture that was made with your Geosource text preset, but the font is small, and the size was 100.
OK i can resize the canvas to a little size, paint…"
"Text brush fonts don't have to be small or stacked close together. It's all a function of how you program the paint synthesizer preset.
And you can use random colors or random indexing in a palette if you don't want to use a source…"
