We've ported Aurora Sky over to Final Cut Pro 3.0. It's a great tool to use for Keep in mind, though, that the functionality of After Effects (AE) plug-ins is limited by what Final Cut Pro (FCP) can do.
When you purchase the AE version, you get the FCP file, all for $169. Or, you can purchase the FCP version only for $129.
NOTE : Aurora does NOT work in FCP 4.0 currently. We are working with Apple to fix this, and will post notification when it happens.
