I haven't seen the effect in question, but first you'll need to generate a "mask" (in another app) in the shape of the person you want particles to fill, then save it in an alpha channel. In particleIllusion you can use the "area emitter mask" option to create the particles in the shape of the person using the alpha channel you created.

A similar thing is here I think:

Here's a video that illustrates the elements I used to recreate the effect:
http://pi.shockingtales.com/videos/orbing.mov
It's a 7 meg Quicktime

Take one shot of your background without the actor and another shot of your background with the actor doing his stuff.

In your paint or compositing program, import a frame where the actor is standing in the pose he'll be in when orbing away, and erase everything around him. Save that with an alpha channel so that you have a frame of the actor as white on a black bg.

In a video editing program or compositor, fade between the two shots, so that your actor vanishes over a couple of frames. Render that out, and import it into pI as a background.

In pI, create an area emitter of the orbing, make it the size of your stage, and check Mask Emitter with Images in its Properties. Use the shot you created in your paint program as the mask. Now you'll have to animate your Numbers graph so that the particles only begin to appear when the actor is ready to leave the scene. The emitter itself has three particle types:

1- Big blue intense particles with very low visibility to create a glow
2- Star shaped particles for the sparkles
3- Tiny particles to create a dust effect.

Now in the Charmed clips, you can see the actor sort of blur away as the particles envelope him. I sorta did this by creating a simple area emitter that birthed particles from the same mask, but used Get Color from Layer to pick up the colour of the actor.

But it doesn't work that well, and looking at the Charmed clips, they probably use a simple Motion Blur that only moves upward rather than just fading out between the live action shot and the plate shot, causing the actor to blur out of existence, which is partially covered up by the particles.

Thanx alot elvis for the information its been helpfull
ive kind of tried it and it looks preety good
one question that im not sure if its he right way
this is what i do:
i use the BG of the fade out
then i put the emitter as make area then use mask and choose
the frame of the guy with alpha
lets say its from frame 35 i then play the animation and start the effect
at frame 35 so it matches the frame i exported
is this the right way?
p.s is there an emitter already that look good with this effect or u created one
by yourself?
thanx :-)

Yeah, that's right, though you may want to start creating the particles a few frames before 35 so that they fill in quicker once the actor hits the "orbing pose". It'll really depend on the footage you shoot, you'll have to make a judgement call on what looks best.

I made the emitter very quickly, it was about a 5 or 10 minute job. I just started with a blank emitter, and used the basic blur particle shape for both the glow and the dust specks, a star shape for the sparkles.
