You can get the XMl via Apple Events which you can call from your stand alone java application. Details can be found in that same document in the Apple Events appendix. Victor, It sounds like what you need is to use FCP XML. This is documented here: <http://developer.apple.com/documentation/AppleApplications/Reference/FinalC… > You would have your users export their projects as XML then your application could read and/or write XML to do whatever it needs to do. You could do this in Java if you want to, as it would be a stand- alone application. I don't believe there is any publicly-available API for reading the contents of a FCP project. I suppose you could try figuring it out on your own but then you're, of course, in the potential position of having to periodically revise your code to handle new project formats. Steve, Thanks for the input. In my case I need to obtain the list of video clips before project is loaded ( e.g. while Final Cut is not yet running ), so can't send an event to application. Is there an alternative method for reading project file directly? Thanks again, Victor The FxPlug SDK is the API for writing a FCP, FCE or Motion plugin that handles some form of rendering to a particular clip with which a particular instance of your effect class is associated. You don't normally worry about other clips in the project. If you have a reason to need information about various video clips, you would get that by sending an AppleEvent to the host application (FCP, FCE, Motion) and then parsing the returned XML. Documentation on those AppleEvents and the format of the returned XML are available on Apple's website. The plugin API assumes an Objective-C plugin interface. If there's a way to call your Java code from within an Objective-C plugin wrapper, then I would think you should be able to do so. I've never tried to do something like that so that's the best answer I can give.

It could be argued that the viewer should be smarter to handle the change dynamically or that FCP should reopen the viewer after some delay. This behavior has not changed since 1.0 as far as I am aware when reconnect was a much more static operation. I am not familiar with FCP Apple Events, but the key would be to know edit which is being viewed ( kFCPOpenItemInProject may be what Rainer was suggesting). Knowing only the file is not sufficient because of course a file can be used in many project in many different places. Even a standard file that is edited only once exists in both the browser and sequence. Isn't there an Apple event that loads an item? You could call that after your update. Might have to introduce a little delay to allow for FCP closing it first. I have a QT file located on a network drive that gets updated (it’s a growing file). I can either change focus outside of FCP or send the Apple Event kFCPMediaFileKey and FCP will successfully re- load the now bigger file (it has the same name). But the big problem is that I lose the file from the Viewer window! The process of reloading the same file happens instantaneously and kicks me out of it.
