Thank you Derek,
The normal Edge Wipe is too narrow a line, it LOOKS like a process wipe. The FXScript DVE's 'softwipe' looks like a controlled dissolve, smoother, wider - a melding of two images rather than a 'window opening to a new image'. But it doesn't work with Intel FCP.
I remember Media 100 used to have controllable dissolves that were terrific, you could choose direction and width of dissolve.
I'm wondering if there is a plug-in series out there somewhere that would do this with the Intel FCP. ???
