Garrick, Sorry I didn't respond sooner, I was out at the end of last week. It looks like your question was answered (technically, if not satisfactorily). Please file Radars for anything you feel isn’t working well or any enhancements you’d like to see. (I do see your update to <rdar://problem/16168064/>, so thanks!) Darrin

I haven’t made a generator since FCP 7 days. Unfortunately I can’t figure out how to make anything useful. I create a generator template in Motion and publish the parameters, say using a 4K settings like UHD. Motion adds width and height parameters but I’m not publishing those (FCP’s generators don’t have those after all). Then when I apply my generator in FCP it’s clearly rendering 4K with that fixed aspect ratio, so it doesn’t even fill the image if the aspect ratio is different. Am I missing anything here? This makes FxPlug generators completely useless in FCP.
I also just noticed that Motion 5.2 creates template that FCP 10.1 can’t load. So I’ll keep Motion 5.1 around, but I fear that someday we’ll need a new feature (like the 4K Ready flag) but at the same time Motion will write files that older versions of FCP don’t like. Is it worth putting in a feature request like Xcode’s deployment target (minimum required version of FCP)? Or can we just have FCP load FxPlugs without templates?
I also noticed that FCP calls finishInitialSetup: on generators only but it’s not on the main thread so setParameterFlags: can’t be used. We’d like a new API in a future FxPlug update to set the enabled states of parameters in response to external data (like hardware). AE has PF_Cmd_UPDATE_PARAMS_UI (which gets called very frequently… we’d be okay with the initial application or loading a project). Updated 16168064.
Let me know if I should file a feature request for this generator / template stuff.
Thanks, Garrick
