was wondering if fotomagico pro is compatible with final cut express ?? thanks for your info

The FxPack that ships with FotoMagico Pro (available as separate download from within the app for Mac App Store customers) is compatible with all host applications that FxFactory supports. As of today these are Final Cut Pro (Versions 6 and 7), Motion (Versions 3 and 4), Final Cut Express (Version 4) and Adobe After Effects (Versions 8, 9, 10 and 10.5 – CS3, CS4, CS5 and CS5.5).
See http://www.noiseindustries.com/support/fxfactory257/ for details.

Honestly, I don’t have Final Cut Express myself, so I never tried. If you want to make sure I suggest you download FxFactory from Noise Industries, FotoMagico from Boinx Software, start FotoMagico, request a FotoMagico Pro demo license from within FotoMagico, choose FotoMagico > Install Plug-ins… and try it out real quick before making the purchase.
