Need Suggestion gamma shift color correction

[Tony Lee]

Do this for me:

Export video to QT on your desktop.
– did that
Use Compressor to create MPEG-2 (.m2v)
– did that

Open original QT in QT player
-did that
Open MPEG-2 file in QT player
-did that

Is the MPEG-2 darker between the 2 Quicktime Player windows?
– yes the mpeg-2 look little darker.

you think because i dont have quicktime pro on my system?

I am having the same issue. Editing in FCP 6.0.2 in 1080p24 DVCPROHD. Exporting self-contained quicktime movie. Importing into Compressor and making mpeg2 using best quality DVD preset, with frame controls on to increase scaling quality to best… otherwise default settings. If I open both the source and resulting mpeg2 in Quicktime, the mpeg2 is darkened considerably.

I have the exact problem. My footage showed the exact darkening of the footage as showing in Lary Sang’s link. I’m using Avid but when I export, I export as Quicktime Reference and that’s where my problem is, Quicktime. Quicktime seems to be the source of the problem but so far I have no found a solution to this problem. I have posted in Quicktime Discussion page and no one seems to have an answer to this problem. This is frustrating that this is a huge problem and no one seems to know what the answer is. Perhaps it’s not widely spread. I would appreciate any help in solving this gamma shift problem with Quicktime.
