Hi Brad,
The short answer is no, you can't.
The long answer is that this is controlled by the user. See the Video
Tab in the Sequence Settings dialog. By default it is set to "Render
YUV material in 8-bit YUV", but the user can override this to render
everything in RGB.
Note that YUV-ness is also dependent on your footage format (and
output format). Almost all users are working with YUV footage, but
many plugin developers test with RGB media such as Tiff images or RGB
movies compressed with the Animation codec. We won't render in YUV if
your input and output are RGB. Your output format is controlled by
your sequence's codec. Check out the FCP manual for more information.
I'd definitely recommend doing your initial testing with DV-NSTC media
and sequences created using the DV-NTSC preset, and then moving on to
handle other cases from there. If you're working in YUV, you should
definitely test with both 601 and 709 media.
Also keep in mind that while practically all consumer cameras generate
YUV footage, some high-end cameras are starting to be natively RGB,
and this trend is likely to continue and work its way to the more
affordable end of the market in the future.
Finally, I'd recommend reading the "Rendering FxPlugs in Final Cut"
document if you haven't already. Rendering in Final Cut is fairly
complicated, and seemingly innocuous changes can change the way we
call your plugin.

I don't know if it's possible, but I'd like to lock final cut pro
into only using YUV fximages. Currently, during previewing in the
timeline I get YUV, but when I try render out, final cut seems to
switch into rgb fximages. Is there any way to lock it YUV?
