Are there any differences between OS 9 and OS X versions?
There are several effects in our Spectra package which have one or two additional sliders in OS X, allowing more flexibility with the effect settings. Some Bravo effects will have a different user interface under OS 9 and OS X. Certain effects such as Blur Edges, Funhouse, Lightning, Laser, Tunnel, and Zoom will use the point picker available under iMovie for OS X. Under OS 9, users will have to use the traditional iMovie sliders.
