If you're looking for more transitions, I recommend Pixelan SpiceMaster 3 for Magix. I can probably do most of the 121 GL transitions with it, with intricate modifications of each, quite simply and without any programming. There are thousands of premade effects, hundreds of masks, that can all be easily manipulated and modified in the Pixelan interface. The possibilities are almost infinite. Add in the other Pixelan effects, and you won't want or need to look elsewhere.
