The core of the Cross Dissolve transition is this FXScript command
Quote
blend(src1, src2, dest, ratio)
This blends the outgoing clip (src1) with the incoming clip (src2) and puts it on the timeline (dest) using the value that changes across the transition from 0 to 1 (ratio).
Ratio is automatically generated by Final Cut as the transition progresses.
I could add 9 inputs, such as 'Amount blended at 10, 20, 30, 40, 50, 60, 70, 80, 90%' and use them in conjunction with some maths to modify the value of 'ratio' and change the command to
Quote
blend(src1, src2, dest, myModifiedRatio)
I'll see what I can do...
