Are you using one of our sequence presets? One possibility is that you are setting the "supports R408" flag, but not the "supports R4FL" flag. You need to specify that your plugin supports r4fl (our floating-point YUV format) in order to receive floating-point YUV pixels. If you like, you can send me your project file (I don't need the footage), which would probably be the fastest way to see what's going on. Does anyone know what magic buttons to push to get final cut to send yuv float to renderOutput? FCP doesn't want to send my filter yuv float. I have a yuv based 8 bit codec in my timeline. Sequence settings match codec. Render settings are set to high precision yuv. My filter is set to recieve yuv, rfl, rgb in the properties. In preview mode, I get yuv 8 bit. However, when exporting to a movie, also yuv, fcp 5.14 insists on sending renderOutput rgb float. I can't test the yuv float routines unless I can force fcp to send me that format. Is there a series of rules by which fcp decides to switch out of the Yuv color format? I don't want to try to simulate the format using my own color conversion routine. I need the real thing.

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… I'm concerned about the workflow: User imports XML file, and referenced media file (perhaps also used in another project) changes. That doesn't sound right to me (the XML file import pretty much only modifies project data today--the QT metedata is changeable but is not user visible and therefor won't affect any existing projects). Nor is it easily undo-able (since the media files could be brought online later and would be unclear where this now media file resident data came from). A separate application that users use could modify those files without this confusion and could still send XML to FCP. I believe that one could write Andreas's autorenamer application (for clips and their subsequent files) today without any change from Final Cut Pro. There are proper QuickTime APIs, or, in the case of the name of the files, Carbon and Cocoa API, that give developers the file level access. The part I think we could improve is to provide access for the cases that are NOT covered by existing API, i.e., you want to use that timecode for something within Final Cut Pro and TC isn't supported for that file format (like AIFF files). As a bonus, I think it'd be great to add in support for retaining TC tracks not already on the media file, since there is no data conflict, but as I stated before, the media file shouldn't be changed, and its data takes priority. If the user chooses to explicitly modify their media files with TC data in FCP, they still have that option via the user interface. Import from and export to an XML format is to provide access to the data model in Final Cut Pro, not to rewrite the access to the operating system. If there are further workflows that are not covered by this plan, I'd love to hear those. PS In the proposed scheme, it seems to me that if you did an XML import with 3 timecodes, then batch captured the media, the TC would stay in FCP, but only resident TC from the capture path would be stored in the QuickTime file. I tend to share Rainer's point of view. There should be something like "updatebehaviour" available even for more things in the XML - like file names (this somehow is already in FCS 1 and 2), also for "scene/take/note/tape" in BWF handling as another example. The original data could be kept with metadata or something like an "item history" so you in worst case can revert to original state - if you keep XML backups. An example: I did an "auto-renamer" for clips in FCP using some text files the user supplies or an XML using scene, take, note and angle. When the XML is imported in FCP everything works fine, but if the clips got offline it will be hell. Same with any audio. for full control, on both existing and non-existing TC tracks, there should be a flag that you can turn on and off and that decides if file or XML wins. This could work like the updatebehaviour flag for QT metadata. In the latter case the actual Quicktime files should be changed/overwritten. I don't see the use or benefit of a situation where you have one TC assigned to a clip in the QT file, and another one in FCP. That is bound to become a problem later on in people's workflows. In other words, I would like to see an optional behaviour where the TC in the Quicktime does get overwritten. That flag should off course default to off, or file wins, and maybe there should be a warning in the user interface upon import. P.S. What should I expect to see when I import clips with all 3 timecodes and have them batch capatured? Will the aux TCs from the XML migrate into the Quicktime file? _______________________________________________ Do not post admin requests to the list. They will be ignored.

The same code running in Motion performs exactly as expected. What could I be doing wrong? I saw in the ScrollingRichText example code very similar to mine running without issue. Any suggestion would be greatly appreciated. Thanks, David This email sent to site_archiver(a)lists.apple.com
