So I think this should be possible. In FCP 5, the FxTemporalImageAPI is only available during render. Since your custom UI is just an NSView, you can cause it to redraw in the usual way: by sending the view a [setNeedsDisplay: YES] message. You'll be asked to re-render when the current time changes, as long as your effect is applied at the new time; you could send your custom UI a redraw message from your render method. Hopefully this will be enough to implement some good feedback. If you are triggering a redraw from your render method, you could probably use the input image passed to your render method rather than using the FxTemporalImageAPI (or the output image if you are a generator). You might need to make a copy, since the images aren't guaranteed to be valid after you render. On one of my trips to the Motion and FCP pods I did notice something interesting. I believe it was the Tracker generator in Motion that had a small window in the effect parameter window that zoomed in on an area where a tracker point was being placed. At least I think it was something like this. Is there any way we can implement this kind of UI in our FxPlugs? Doing a zoom of a snap shot as Custom Ui should be straightforward I think, but I believe the little window got updated whenever the playhead moved as well, so I'm not sure how that works. That was kind of neat and would be a cool parameter to have. _______________________________________________ Do not post admin requests to the list. They will be ignored.
