Not the same as brightness contrast \ in the timeline with the finished clip.

Good day. Please tell me, I'm using FCPX and I have 10.2.3 is not the same as brightness contrast \ in the timeline with the finished clip. Why this discrepancy in brightness between the mounting table and the finished clip? Please tell me why this might be? JPG and invested. Thank you!

I found the problem, search in google "QuickTime Gamma Shift", not about a bad decision https://discussions.apple.com/message/23394401#23394401

That refers to a different version of FCP. Most of the gamma shift reports are for legacy FCP or for QuickTime on Windows.

Dear Tom Wolsky, yes, I understand that, but I have a problem in fcpx in the latest version. I assumed that the only problem I have and unfortunately reinstall fcpx and cleaning folders did not help and the problem lies elsewhere. At the moment, I found a solution to the consequences of this problem, as described above. But if anyone knows the solution will be very grateful. Thank you!

That gamma correction should no longer be necessary, which makes me think there is something else going on in your process or media, but good that it works for you.

Dear , Tom Wolsky, if Do you have a suggestion that might affect my problem . Perhaps the calibration of the monitor - and I use argyllcms.com/ displaycal.net/ program for calibration . But I tried it and turned off the color profile that does not work ..

FCP is designed to work with ColorSync and the default color should be used in system preferences.

What is your Footage, Timeline, and export format/settings?

I would suspect that the problem lies in the different color spaces/depths of different formats (ie. DV vs HD vs UHD)

The colors recorded in a 10bit 4k file, will never be exactly the same in an 8bit h.264 HD export, and an HD file encoded for DVD will loose color info as well.

Dear, Tom Wolsky, You really were right, I deleted the program to calibrate the monitor, and all okay!!
