Here the things are a bit different as the customer wants to see the timeline with scenes sorted by angle from a previous unsorted sequence xml - so obviously I have to create some workaround like adding the angle to "commenta" or "commentb" field. But in any case it would be nice to have the "angle" somehow included into the "logginginfo" as this nowadays is an important info. Also a nice feature would be if the "angle" in the logging window would be separated by "-" instead of "_". Hey Andreas! <defaultangle> is used when a multiclip is created to indicate angle 1, 2, 3, 4 etc that you want this clip to be put at. So it is exists only on a <clip> and not on <clipitem>. This in no way determines the active angle at any given time, just which order the clips are put into the multiclip as angles. It sounds like you want to specify which angle is used in each instance of a multiclip that is used multiple times in a timeline. For that, you want to use <activevideoangle> and <activeaudioangle> flags as described on page 22 of the XML documentation (http:// developer.apple.com/appleapplications/download/FinalCutPro_XML.pdf) I got an app which does analyze a sequence and allows to re-order, re-name (etc.) clip items. One thing where I stuck is to apply a "defaultangle" as there are several clips of the same scene with different angles laid down to the sequence. I can apply a "defaultangle" to a "clip" but not to a "clipitem" (as written in the manual and as it works in practice). Is there any reason for that which I don't understand? Do I have to create a "single clip multiclip item" ? This email sent to hju(a)apple.com This email sent to site_archiver(a)lists.apple.com

acceptable XML for P2 log and transfer in FCP6?

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Hi folks. Any thoughts, oh fellow Pro Apps developers? --> Michael B.

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… For a side project here at Pixar University, I'm writing a standalone companion app to modify the XML for P2 data (Panasonic's format). I'm trying to modify the XML before the data hits FCP or Avid, so that folks can choose whichever they want and be more easily able to conform later, rather than having them do it inside of FCP's log and transfer window or Avid's equivalent. Ideally, my editors have a bunch of columns of metadata they'd like to see (like script number, DP, director, Description, etc.), and I had hoped to just add those to the <ClipMetadata> section. So I can add these, and FCP eats them okay, but unfortunately, new columns that I added don't show up in FCP (which isn't the end of the world), but worse, fields that FCP has (like Description) don't have the metadata values filled in.

I'll take a look and see if something unexpected is happening. I'm finding I get the incorrect images returned using FxTemporalImageAPI when viewing in the Digital Cinema Desktop Preview. So, to reproduce, I've added the following code to the SimpleMatte sdk example. At the beginning of renderOutput, I've added: id temporalImageAPI = [_apiManager apiForProtocol:@protocol(FxTemporalImageAPI)]; if(temporalImageAPI!=NULL) { FxBitmap * theBitmap = NULL; BOOL result = [temporalImageAPI getInputBitmap:&theBitmap withInfo:renderInfo atTime:renderInfo.frame]; I've also changed it so the mayRemapTime property is set to YES, and added the FxTemporalImageAPI protocol in the Info.plist. When the plug-in is applied in the normal viewer, the print statements produce values you would expect given the images. When displaying in the Digital Cinema Desktop Preview, the values seem to be incorrect. This email sent to pschneider(a)apple.com This email sent to site_archiver(a)lists.apple.com
