Gert,
What I did was take the 20 second clip, place on track one in timeline, split it at 10 seconds. Then apply the particle effects needed on one clip (up to 7), then apply the particle effects needed on the other clip (up to 7)again.
In the Particle track, one cannot stack the effects on top of one another as one can in the video tracks.
Hope this answers your questions, if not then don't hesitate to reply back in more details.
Bill
Thanks,
