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… NTSC is the sequence speed, in other words if it's true, then the actual frame rate is slightly slower than the timebase. Thus 30 fps becomes 29.97 fps, and 60 fps becomes 59.94 fps. The timebase (i.e. the method of counting frames, or the frame number before which you turn over to the next second) remains 30, or 60 fps, respectively. All of this is distinctly different from DF/NDF, which affects also the method of counting frames, but in a different way than above. In DF, 2 frame values are skipped at the top of the minute in 9 out of 10 minutes, in NDF no values are skipped at all. Note that DF/NDF does not affect the actual playback speed, while NTSC true or false does do that. This will be imported as 29.97 frame rate with NDF. If I export as XML I do see the same. I also can switch in the sequence settings from DF to NDF. Using a sequence preset for 30/60 NDF I can't switch between DF/NDF but the tc in the XML is always DF????? Using any 29.97/59.94 DF sequence preset I can switch as with the above example to NDF in FCP and the XML stores the NDF TC flag, string and frame. So from what I tested I got now: if NTSC is "TRUE" then I'm able to see both DF/NDF timecode and frame and the correct DF/NDF entry if NTSC is "FALSE" and TC is NDF I always will get DF timecode and frame - hmmm??? a) If I create a timeline using some codec, some size and set the editing timebase to 60, I get a NDF timecode in FCP (start TC 01:00:00:00) b) If I create a timeline using some codec, some size and set the editing timebase to 59.94, I get a DF timecode in FCP (start TC 01:00:00;00) So far it's easy. If I create XMLs out of those I got following: a) editing timebase=60, NTSC=FALSE, timecode=DF (<string>01:00:00;00</string>) b) editing timebase=60, NTSC=TRUE, timecode=DF (<string>01:00:00;00</string>) So I am a bit confused about these things. How is it handled? 30/60 always seem to be drop frame internally always, so when reading out an XML and encode the timecode you will get DF timecode always. Depending on what you do with the data this might give you a) wrong frame numbers when the timecode is converted to frames (when based on the TC string) b) wrong TC (when based on frame numbers) Questions are: a) can the NTSC flag be ignored and if yes why it is there? b) why is the "rate" there twice ('main item', timecode entry) and how do they relate?

Haven't tested it though. I have been using our FBO library for quite some time now in our own Cocoa applications. This works wonderfully and all is good in the land of our applications. Now, I need to use these within our FxPlugs. The plugin produces the sought result in the view as long as no other filters are up the hierarchy ( applied to the result ). If there are other filters or blending with other images they are ignored. I believe it is related to calling glBindFramebufferEXT( GL_FRAMEBUFFER_EXT, 0 ); which is resetting the drawing buffer to the view. Then BAM!!! I realized that FxPlug needs to be rendering to a different buffer that is then passed up the hierarchy ( not the screen, DOH!!! ). THE ACTUAL QUERY: How do I retrieve the current FBO index and restore it when other rendering to other FBOs is complete? I tried storing GL_DRAW_BUFFER and setting it later but that does not seem to work. Thanks!

The last theme looks to be using one of the curtains from Motion, and since this is a Keynote theme, it's fairly easy to just pull out the movie and use it elsewhere.

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Hi all, Though I'm not really involved I think it's worth to spread the news. Regards Andreas First time ever there will be a FCP user meeting at IBC Amsterdam. "This event will be the largest gathering of FCP Users and Gurus on the planet during IBC week." Michael Horton says. So if you live in Europe and/or want to attend the IBC, this event is a must. For more info http://www.lafcpug.org/ibc_2008. If you want to go there you may contact Michael Horton (michaelh(a)lafcpug.org) and tell him about your current projects which might be interesting to a wider audience. Maybe you can present your project(s). And spread the word about this event as well. P.S. You can pre-register for IBC. This will give you free entrance to the exhibition halls and a free travel pass for Amsterdam: http://www.ibc.org/cgi-bin/displaypage.cgi?pageref=1104 _______________________________________________ Do not post admin requests to the list.

If order wasn't taken into account it is unclear what should happen. I am encoding a simple sequence, and the clipitems don't appear in the same order in the XML that they are supposed to appear in in the sequence. I am getting some weird results with that. So: Does the encoding order matter for clipitems of a track? This email sent to hju(a)apple.com This email sent to site_archiver(a)lists.apple.com
