Re: Low precision on time remap

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com ky I want to overlay clips from recording devices that are free-running (not jam-synched). Even though most of the clocks are pretty accurate, these are clips of live events that last a long time and over the course of many minutes it is not unusual for them to drift apart from one another by an amount that needs to be corrected. Time remap seems like a good mechanism to adjust things back into sync. But the speed value only seems to be able to retain numbers up to a precision of two decimal places. For example, enter 100.12345 in the user interface and 100.133 is what gets stored in the XML, which is not even rounded properly. The residual error over the length of an hour can be hundreds of milliseconds, which is not acceptable for many synchronization purposes. I can't figure out if this is an artifact of the user interface or some fundamental limitation. Is there a sneaky way to specify a remap speed with greater precision? _______________________________________________ Do not post admin requests to the list. They will be ignored.

You have audio that is not in sync with video and are trying to adjust the speed the video to match the audio? Is you audio fine at the start, and then drifts linearly , or is completely ok and then at some point goes off? In addition, I gather from what you are saying that you are not really using xml is this workflow, but rather you are using that simply to display the values of the speed keyframes. Is that correct?

Suppose, I'd like Final Cut Server to open/ prefetch each clip in my project whenever I open the project with Final Cut Professional client. Can I do it just with the client side plugin, or would it require some kind of server side plugin as well?

Issue AppleScript to make the FCP export XML format of the project 4. Parse the XML. I used tree-based XML parser from the Cocoa. Because the XML format for the FCP project is known, it would be easier to use tree based parser, instead of event based parser. The tree based parser is NSXMLDocument.

My first question is: what SDK can I use to read from project file? So far I couldn't find anything pertinent in FxPlug SDK 1.2. Am I looking in the right place? 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 original application I have to base my prospective plugin on has been written in Java. Would it be possible to implement FCP plugin in Java? 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. _______________________________________________ Do not post admin requests to the list. They will be ignored.

Pro-apps-dev mailing list (Pro-apps-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/pro-apps-dev/site_archiver%40lists.a… There is no spec or API for the FCP project file format. The format has never been revealed to any developer. The way to get information about FCP projects is via the XML interchange format. You say you want to get the list of clips before that project is loaded - why? Can plugin have an access to the host application functionality when host application is not running yet? I suppose you could try figuring it out on your own... Do you know where I can find specification?

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 This email sent to evershen(a)apple.com This email sent to site_archiver(a)lists.apple.com
