Hi,

I am currently working on a full rewrite of this import mechanism to make 
it much more powerful. I hope to finish & commit it tonight, it should fix 
the problems you describe.

The changes include:

* Ability to import keyframes to some other effects like volume, 
brightness, gamma as a first step
* Ability to import only a zone of the keyframes, and add an offset so that 
keyframes start where you want in the dropped transition/effect
