I am wondering if scripting can be done with the Pan/Crop event in terms of doing pan and zoom for a given event on the timeline. It is not obvious from reading the scripting API document whether this can be done or not.
Can't answer the scripting thing - no programmer here! - But, what are you trying to achive? If it is to repeat an "effect" you like to other clips, I do this in P/C by using the "Paste Attributes" from one clip to another - neat new V4 Function! You could also create a "Preset" call it "MyNewPreset" and then reuse it on other clips.
