I'm tryng to get my head around what happens
to a FxPlugin (especially a generator) when it is trimmed
or cut inhalf then it's parts are moved around on timeline.
And what a plugin which has reference image parameter(s)
should/could do to appropriately update itself.
I would assume the FCP 7 will make a copy of the
generator (or clip+filter), then make two API method calls,
to which our plugins can optionally respond:
1.) a method invoked to the original generator
passing it the old and new duration. (to the 1st half of cut
object)
2.) another method invoked to signal the new copy
of the generator, passing it the old and new relative start
frame offset.
(to the 2nd half of the cut generator)
My plugin should respond to these two methods,
and update it's internal state for accessing the appropriate
frame ranges of it's reference image parameters
to meet the new post-cut state of the edit.
Is my assumption anywhere near correct?
If so, what are those FxGenerator 2 methods to which
my FxPlug should respond?
If not, how does it really work?
And how should/can my generator respond to a cut edit,
so that it can appropriately access it's reference image parameters?
