blood spurt effect problems..

[Aschu]

So i got some free effects from detonation films and i put in a blood spurt just to mess around with some effects and such. When i re-size the effect clip and then use multiply to take out the white background, there are black lines that outline that effect clip. How do i get rid of them.

From their website:

NOTE TO FINAL CUT PRO USERS:
The latest version of FCP has a glitch that causes a black line to appear around resized "Multiply" transparencies.
To fix this use the Unsharp Mask in the Sharpen effects folder, combined with a bit of crop and edge feather. (Double click on the clip to bring it up in the Viewer window, select the Motion tab, select Crop)
Other programs and earlier versions of FCP simply need an occasional touch of edge feather.

But I don't really like the 'multiply' approach... you never really get a solid color out of it.
