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 site_archiver@lists.apple.com
