In Final Cut, you should expect to get RGB_GAMMA_DEFAULT_MACINTOSH_DISPLAY if your sequence is set to "Render in RGB", and RGB_GAMMA_VIDEO otherwise. This assumes that your plugin doesn't handle YUV formats; if it does, you can expect to get the YUV variants (Rec 601 or Rec 709). In Motion, you should always expect to get RGB_GAMMA_DEFAULT_MACINTOSH_DISPLAY. This is the current behavior of the shipping apps; we may change the behavior in the future. For example, the LINEAR option is there as a placeholder in case we want to start processing linear. I'm not sure why you would be getting linear data in FCP or in Motion, unless your media is actually linear, but not labeled as such. Neither app currently linearizes during processing. I've found that in Motion, I always get back kFxImageColorInfo_RGB_GAMMA_DEFAULT_MACINTOSH_DISPLAY from [inputImage colorInfo] in renderOutput:withInput:withInfo. In FCP, I always get back kFxImageColorInfo_RGB_GAMMA_VIDEO. This is with RGB images, regardless of depth. I tried this with lots of different input images, still, synthetic, and video, with the same results. Using some clips that I created with varied color profiles in AE, it appears that in Motion, the input image has linear gamma at the point that it reaches my FxPlug. The compensation suggested by Pete Warden's message "Recommendations for plugins that want to work internally in linear color", <http://lists.apple.com/archives/pro-apps-dev/2008/Feb/msg00015.html> seem to seriously overcompensate for the gamma in FCP, and is unnecessary in Motion. Some of my code wants to work in linear rgb, but I don't see how to interpret these results. This email sent to pschneider@apple.com This email sent to site_archiver@lists.apple.com
