I'm actually going to have multiple image inputs.
First, I tried writing this plugin as a Filter, then re-wrote it as a
Transition.
Both had too many problems to be useable.
Especially in FCP, where there are many limitation on the primary
input image.
Now, I'm trying to re-re-write it as a Generator.
The images are oversized.
Here are 3 main issues / questions:
1. Is it possible to have a 4096x2048 image clip
dropped onto a 1920x1080 timeline in FCP, without
the 4K being conformed down to a 1080p?
Can the user have two or three or four 1080p video tracks
each with a 4096x2048 image on them?
But, Transitions plugins only have 2 inputs...
and Motion doesn't accept Transition plugins... yet.
2. Can the Filter or Transition control the conform?
That is, can a FCP Filter (or Transition) resize a 4K input image
down to the proper (1080p or 720p) size for the timeline.
3. Is it even possible to cut a clip that has a Transition over it's
entire duration?
I can't seem to cut the clip that has a full-duration transition on it.
Maybe I just don't know FCP well enough.
But, it does seem to me that a Generator should
be able to either control it's duration, or have some
way of indicating to the user it's optimal duration.
True that some Generators have no predetermined duration.
But, other Generators do have finite durations, and
outside of that range they can't generate anything.
The user shouldn't have to visually inspect the full
clip length, searching for the end of the Generator's images, manually.
This has prevented me from writing any Generators to date
(eg: explosions based on physics, etc ...
anything driven by real world timing/durations).
I'd love to put a "calc duration" button into my plugins
that the user could click, and have my plugins analyzed
the content/parameters and set the optimal duration.
I have many uses for it on my existing Filters and Transitions.
But, it seems even more useful for a Generator plugin.

I'm writing an FxGenerator that has a Reference Image parameter.
When the user sets this parameter, I'd like my plugin
to automatically change it's duration to match the
duration of their Reference Image clip.
Is there a way to do this?
If so, how?
No, there's no way to do that. It sounds like what you actually want
is a filter. It will always be the length of the item to which it is
applied by default. (In Motion you can make it longer or shorter by
dragging the ends of the filter item in the timeline.)
