when you apply a matrox organic wipe, the organic wipes page appears:

to set up an organic wipe:
1 choose the type of effect you are looking for in the directory.
2 click the particular effect you want from the effect list.
3 to see a preview of your effect at any time, click the preview button.
4 to create a soft edge on the border of your organic wipe, select allow changes, then drag the softness slider. the higher the value, the less sharp the edge of your organic wipe becomes.
5 when you are satisfied with your effect, click ok to return to your timeline.
the matrox organic wipes are not transformable (that is, the transform track is not available when setting up organic wipes). you can, however, add your own patterns as explained in "adding your own organic wipe patterns" on page 78.
