If we are getting fields back from the temporal API, but we want a
full interlaced frame, is the following a valid way for us to
re-create the interlaced frame:
1) Get 720x240 field buffer at time n
2) Get 720x240 field buffer at time n + .5
3) Combine the two fields (field order correct of course)
No unless you cache the first field result as a full frame internally as
you will be called twice, the second time at frameNum.5
We do need actual fields in our plugin and not something that is line
doubled.
And Paul is right that media does get scaled automatically, which is
nasty, but I thought after much searching I found a way to turn that
off. Yet another manual entry for us I think.
Thanks,
Micah

Right now, FCP's implementation of the temporalAPI will always give
you the native format of the media. In other words, if you use the
temporalAPI on a progressive clip, you'll get a full frame back, even
if you are in an interlaced timeline. This is arguably confusing,
since it's not the same as the input image that we pass to filters
(input images are in the timeline format, not the media format). I
think Paul Miller has a good point here.
