need help with zoom

[trolltuning]

I have started playing with zoom to warp one person in and stand them next to another (by stacking another clip next to it) but I don't know how to stop the motion so the warped-in person stays on screen. How do I keep the dstx value constant after frame 64?

loadplugIn("C:\Program Files\AviSynth 2.5\plugins\zoom.dll")
vid00=AVISource("D:\avis\cindyalone.avs")
vid01=vid00.converttoRGB32
ReduceBy2(vid01)
#ReduceBy2()
zoom(factorx="n<41 ? pow((n+1)/41,0.5) : 1", factory="n<41 ? pow((n+1)/41,0.5) : 1",dstx="n<41 ? width/2 : width/2+5*(n-41)",angle="n<41 ? 18*n : 0")
#(factorx="n<41 ? pow((n+1)/41,0.5) : 1", factory="n<41 ? pow
# ((n+1)/41,0.5) : 1",
##dstx="n<41 ? width/2 : width/2+5*(n-41)"
#Info()
#zoom(angle="n<41 ? 18*n : 0")
#stop motion in frame 65

zoomed ++ vid01.trim(65,0)



that should do it. unfortunately i've never used the plugin zoom before, but have worked around it :) there's possibly more on the subject in zoom's docs (if it has any)

Thanks but that should jump the position from where it is in frame 64 to the position it happens to be in frame 65. What I really wanted to do was find the position (dstx) in frame 64 and then nest another conditional statement or write a function so that the position stays there after frame 65, but I'm not sure of the syntax.
