Your explanation helped me very much!! Sounds like FxPlug is where I should focus. (pro apps) Curiousity... What does DVD Player use? If needed to write some Film LUT code or custom video manipulation for a project, can I run an FxPlug (or CIFilter) via the DVD Player app (or a custom DVD player app)? I'm often working on film projects. And issues come up, like specific film stock color matching, and custom anamorphic image squeezed formats, or AOV imagery, etc. occassionally passed around in QT movies (I'll use FxPlugins) or on DVD (I'll use ??? - no idea - CI, FxPlug?). Can I get DVD Player to use (or write a DVD player app that can use) FxPlugins? Thanks again, Paul. -- Brian _______________________________________________ Do not post admin requests to the list.

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Hi, Brian, I agree, it is confusing. - Paul On Jan 27, 2008, at 4:38 PM, Brian wrote: Sorry for interjecting another newbie question.

They both sit on top of OpenGL; they are not really related to each other. It would be possible to write an FxPlug filter that was implemented using a CIFilter; you'd simply create a CIContext for the destination buffer, and CIImages out of the input buffers. Our example FxPlugs are a bit lower-level, and run GL fragment programs directly on the supplied GL textures. This is pretty much what CI does as well (a CIKernel is basically a GL fragment program). Why do we have two separate things? FxPlug and CoreImage have slightly different goals. For example, one of the main features of CI is that it will run your shader in software if the graphics card doesn't support fragment programs. The Pro Apps have higher system requirements than Mac OS X, so we don't need that fallback. FxPlug also has some features (particularly related to sampling images at various times) that CI lacks. Which technology should you use? It depends on what you plan to deliver. FxPlug is the image processing API for Final Cut Studio, so if you want to write a plugin for Final Cut and/or Motion, write an FxPlug. If you want to write a plugin for other systems (like Quartz Composer, or Pixelmator), write a CIFilter. If you want to deliver your plugin to everyone, you'll have to separate your algorithm from the plugin packaging, and make both an FxPlug and a CI wrapper.

While working on that I may have come to a point where do have a lak of understanding. Within the XML an audio node may look like the below: <file id="TD26 L016 Gwen"> <name>TD26 L016 Gwen</name> <pathurl>file://localhost/RAID/TDI/TDI-026/026_Lines/ TD26%20L016%20Gwen.wav</pathurl> <rate> <timebase>30</timebase> <ntsc>TRUE</ntsc> </rate> <duration>674</duration> <timecode> <rate> <timebase>30</timebase> <ntsc>TRUE</ntsc> </rate> <string>03:09:22:25</string> <frame>340885</frame> <displayformat>NDF</displayformat> <source>source</source> </timecode> <media> <audio> <samplecharacteristics> <samplerate>48000</samplerate> <depth>24</depth> </samplecharacteristics> <channelcount>1</channelcount> </audio> </media> </file> So the timecode information says that this file is NTSC(True) 30 frames per second NDF. From my understanding there can't be this kind of TC in FCP as the current handling of 30 NDF is not NTSC - at least for video. Or is there a hidden handling which do match the options of current audio HDRs? It's even more confusing for me if I look at media using 24 frames per second which won't show the "NTSC" node for the rate: <file id="TDI_FULL_OPEN_REVISED"> <name>TDI_FULL_OPEN_REVISED</name> <pathurl>file://localhost/RAID/TDI/TDI%20Final%20Theme/ TDI_FULL_OPEN_REVISED.WAV</pathurl> <rate> <timebase>24</timebase> <ntsc>TRUE</ntsc> </rate> <duration>1461</duration> <timecode> <rate> <timebase>24</timebase> </rate> <string>23:58:33:10</string> <frame>2071522</frame> <displayformat>NDF</displayformat> <source>source</source> </timecode> <media> <audio> <samplecharacteristics> <samplerate>48000</samplerate> <depth>24</depth> </samplecharacteristics> <channelcount>2</channelcount> </audio> </media> </file> This email sent to site_archiver(a)lists.apple.com

So, please forgive me if I say something too stupid. :-) Is it possible that the temporal API was trying to get a non-existent image somehow? Perhaps a +0.5 (second field)? If the video was interpreted as "interlaced", the image would exist. But, if it were interpreted as "progressive", there'd be no +0.5 image. Perhaps the update turned off field processing? (Or altered a default or preference setting, etc.) Something that might either cause the Video from being interpretted as interlaced vs progressive, or change the render mode from i to p. My attention was just caught by the good G5 trying to process "interlaced", but the bad G5 processing as "progressive". That seems like an important clue. It'd be interesting to see if the bug subsides, if the video icould be marked/interpreted as "interlaced" again. Just a thought. Sorry if it was a dumb one. -- brian -----Original Message----- >From: Micah Sharp <micah(a)redgiantsoftware.com> >Sent: Jan 25, 2008 4:54 PM >To: pro-apps-dev(a)lists.apple.com >Subject: question about fcp 5.1.4 > >Hi, I have a bug in our FxPlug in FCP 5.1.4 only, where calls into the temporal api are causing some kind of exception and execution returns back to FCP, with no more plugin code being executed.
