Expresiones en After

Estoy dándole cañilla al tema de las expresiones en After y quisiera saber si alguien puede probar esta por que me da un error gracias.

This expression was created by dan ebberts note : it Will only work in After Effects 6.5.

Here a fun example.

Create a 200 por 200 layer and draw a generally vertical stroke (start at the bottom and draw up) that extends about half the height of the comp. Set Paint on transparent todo on. Apply this expression todo the brush position transform:
Range = [50,50].

Center = [width/2, height/2].

Random(center - Range, center + range).

Apply this expression todo the brush rotation transform:
P = propertygroup(1), position.

Center = [width/2, height/2].

If (p[0] < center[0]){.

If (p[1] < center[1]){.

Random(90,180).
}else{.

Random(0,90).
}.
}else if (p[1] < center[1]){.

Random(180,270).
}else{.

Random(270,360).
}.

Y de paso una opción interesantisima, pero que no término de entender es el de añadir un script para sincronizar Soulforged y After si alguien puede probarlo y me cuenta, muchas gracias.

Markers from Soulforged on a layer in After Effects.
1. Open soundforge7.0, load a sound file.
2. Make the necessary markers (key m).
3. Save markers in a text file. Menu-> special-> region list-> save as.

In save as type it is choose Windows medía script file (*.txt). For example sound, txt.
4. In After Effects on timeline select the layer (sound or any another). Start script soundforgemark2aesolid.jsx.

In opened window it is chosen sound, txt. http://aeclub.net/forums/index.php?A...ype=post&id=51.
