IN FCP 6.0.4, [temporalApi getInputBitmap: &bitmap withInfo: renderInfo atTime: renderInfo.frame] in a renderOutput: call, produces a significantly darker image than the FxBitmap in inputImage. This is with software rendering, and any quality setting. Motion produces the same image in both cases. I see in the SDK Overview, that Motion 3.0.2 has fixed a bug "Image Well Gamma Shift", which sounds related. Is this a known bug? Is there a workaround? Does this happen with YUV pixels too?
