Generally I feel that the effects and transitions are a bit complicated to use. Options are hidden away in submenus etc.
I'll use one of the effects I'm using the most as an example; the Pan & Zoom effect.
Looking at the window it's very empty, all options are hidden away in a submenu.
To custom zoom, one of the basic features of this effect, it takes 5 steps;
* Option menu
* write value.
* Click OK.
If the amount wasn't right you have to go through 5 steps again to change the zoom value.
Why not move the basics out from the submenu into the main effect interface?
Have a look at my quick mockup:
here you have 0 or 1 click to change zoom level, depending on if you want an OK-button or live updated values.
This was just one effect. If you look at them all there's thousands of hours wasted on just clicking menus and bringing up options.
