From as far as I can tell even with all the render setting set to YUV, it still switches to rgb on render. The timeline only contains YUV video. My initial problem with RGB is that I found color shifts when trying to use it inside another plugin that I wrote. It's also really expensive, because of the need to work with 16 or 32 bit float and convert back to YUV. 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?
