I apologize. >From talking to some of the other engineers who worked on this before me, it seems that the shared context is actually created in a way that makes it compatible with the current context. At the time we added the sharedContext variable, we did so because we thought that it would be needed by 3rd party developers in order for you to create pbuffers that shared with the context Motion was rendering to. It turns out we could have just recommended using CGLGetCurrentContext (). It's not always the same context as the shared one, but because they both have the same parent, it doesn't matter. They get you the same thing. So it seems at this point that you can use either. But it's probably safest for forward compatibility to use the shared context in case we ever change how that works. No, I can't think of a reason why you would ever want to use the current context. It's likely that doing so will either not produce any noticeable results or will produce bad results. That context is probably whatever context was being rendered to before you were called, and may not even have been set by the application. (I'm not positive of that, but my point is don't assume it has any particular significance.) I'd like to know if there's a reason to use the current context in Motion vs. the renderInfo.sharedContext. Is this in FCP, Motion, or both? As far as I know, the contexts should be the same in FCP. Can someone tell me the difference between the current context (derived from CGLGetCurrentContext()) and renderInfo.sharedContext at the start of -renderOutput? From what I can tell, they're different. I realize renderInfo.sharedContext may be NULL when rendering to a bitmap.

Re: id attributes in FCP XMLs

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Hi Rainer! The id can refer to or be referred to within the same XML document. So, "yes".

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 am wondering about the 'scope' of the id attribute in XML documents. The documentation says about ids: The id attribute lets you share information between certain "peer" elements—elements that are not in an element/subelement relationship with each other. If an element provides an id attribute, Final Cut Pro registers this element in a reference table during import and translation. Then, during subsequent translation, other elements can reference this registered information. For example, the clip information for a video track in a sequence may be identical to the clip information in an audio track in the same sequence. Rather than repeating this information for both tracks, you can encode it once and then reference the information using the id attribute. My question is if I should expect to ever find id attributes in a clipitem in a sequence that refers to something outside of the sequence, like in another sequence, or in separate clips within the same XML export from FCP? The use of the term 'peer' seems to imply that the answer to my question should be no. Is it, really? This email sent to hju(a)apple.com This email sent to site_archiver(a)lists.apple.com
