I don't see how things get too complicated. For Frame rate: If an effect is applied to a group or emitter with continuous frame-number generation possible, then return the fps of frame rate of group. Otherwise return fps of clip.
For duration: return duration of group or clip. If the user has an emitter with no particular end-frame, then you can return INT_MAX, but I assume in most practical situations the duration of the group would suffice that the emitter is within.
And you might ask what if clip is of different frame rate than group/sequence? This is info I've been wanting to get internally for 12 years, and would allow us to perform frame rate conversions within FCP/Motion in a very intelligent way. And high-quality frame rate conversion wasn't possible in pre-FCP X versions because the frame number used to retrieve frames internally was an integer… so you couldn’t retreive all 60 frames of 60p footage inside a 24p group/sequence. This something that could/should have easily been made possible in FCP X/Motion 5 as part of the great upgrade. Are images now retrieved by plugins in floating point time?
