Asynchronous Decompression in Final Cut Pro?

site_archiver(a)lists.apple.com Delivered-To: pro-apps-dev(a)lists.apple.com Details: Thanks in advance for any help, Andreas Wittenstein BitJazz Inc. http://www.bitjazz.com/sheervideo/ _______________________________________________ Do not post admin requests to the list.

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… My real-time lossless SheerVideo codecs don't play back nearly as quickly in Final Cut Pro as in QuickTime Player and other QuickTime applications. On investigation, I see that whereas QuickTime Player typically decompresses up to 30 HD frames concurrently when playing back a SheerVideo clip on a dual 2GHz G5, Final Cut Pro always decompresses a single frame at a time. Any ideas why? [I would hope a $1000 Final Cut Pro application would have better real-time handling than the freebie QuickTime Player or $30 QuickTime Player Pro.] Each Sheer decompressor • implements 'GetMPWorkFunction()', 'QueueStarting()', and 'QueueStopping()'; • delegates 'GetBaseMPWorkFunction()', 'Busy()', and 'FlushLastFrame()'; • sets the 'canAsync' flag in the 'ImageSubCodecDecompressCapabilities' structure in 'Initialize()' • and 'Preflight()'; • sets the 'codecCanAsync' and 'codecCanAsyncWhen' flags in the 'flags' member of the 'CodecCapabilities' structure in 'Preflight()'. What else does it take to persuade Final Cut Pro to call the Sheer decoders asynchronously? QuickTime Player 6.5 typically stacks up to 30 calls to a Sheer decoder's 'BeginBand()' before the first 'DrawBand()' is completed and 'EndBand()' is called. Final Cut Pro 4.5 HD, in contrast, never calls 'BeginBand()' again until it's finished 'DrawBand()' and 'EndBand()'. This email sent to site_archiver(a)lists.apple.com

Martin, With Apple Knowledge Base article 301048 I read that motion projects can be renamed with .mov vs. .motn for Shake compatibility. I would have to think this might work with your QT app? I'm trying to view Motion projects in a custom QT app but am not having much luck. Some background: Project files created by Apple's Motion app are saved in XML format with the extension ".motn". QuickTime player will happily open a Motion project and displays it as a movie with a single video track with "Format" of "Motion". You'd imagine that QuickTime being QuickTime, you'd get the same result in any QT based app but this isn't the case. So far I've found only Compressor will open the files successfully.
