When I export an HDV clip into Motion 3, apply Optical Flow frame blending, then export to FCP as an HDV file, the brightness and saturation of the resulting QT file are essentially identical to the original. But when I begin by exporting the original clip to ProRes(HQ) via QT conversion or Compressor, bring the ProRes file into Motion and afterwards export to FCP as HDV, the resulting clip is considerably darker (and maybe more saturated) than the original. In the QT conversion, I'm not applying any brightness or contrast filtering. Any clues about what I'm doing wrong?
