select the clip, then hold ctrl and press 1 2 3 4 5 6 7 8, then drag out to desk (still holding ctrl while dragging). all the soft effect will be at desk now. then just copy to whatevr clips you like, you can select multi clips then drop th effect to them at once.
note: you don't need to press all the 1 2 3 4 5 6 7 8, just the numbers (soft effect) that you want to copy. there's a small number near every soft effect.
i'm not currently at my smoke, i hope my memory is right.
