a transition's tale



iMovie has a lot of quirks. a major one is how it differentiates between an effect (a.k.a. 'filter'), a title (text-based effect), and a transition. rather than unifying the interface for basically three vary similar operations, iMovie's API uses three different methods to call the plug-in. the transition is the least intuitive of them all, and the SDK's examples are an exercise in bad code design.
consequently, we were loath to go through the same process we did when we developed our first (PPC-only) transition way back when. but we could not afford to put it off any longer, and started transitioning the first transition based on our reference code for the effect plug-in (at least we knew that that code worked). we ran into a lot of snags, but finally we prevailed. as of today we now not only have a reference transition running universal, but also the first transition published on our web page (pixel-pull transitions - thank you for asking). we now can port transitions and effects to Intel, and intend to bring our most important ones over as fast as possible. the new versions sport most of the same improvements as out effects, plus they now come in a single bundle (instead of three different plug-ins).
