With regard to the brightness differential, I’m having a similar problem. What makes this so frustrating is that I am using the same lcd monitor for both the Premiere program monitor as well as to view the encoded mpeg file after output. The picture within Premiere is nicely balanced but when viewed in media player after encoding, it’s dark and muddy. I have two lcd monitors and both exhibit the same results. The differential is so great that it is impossible to figure how much to compensate in Premiere so as to normalize the final. And I don’t know where to look. Is it Premiere? Media Encoder? or Media Player? I’m not at a stage where I can master a DVD or Blue Ray so I can’t test that. Does anyone have a thought about how I can get a handle on this?
