I am sorry, I am so present right now...but I experienced another weirdness.
Maybe my FCPX has a bug somehow.
Usually, my colours were presented quiet accurate in the Viewer in X and the difference when watching it over Thunderbolt MiniMonitor on external screen was minimal.
Now suddenly, when all looks good in the viewer, the export has an extreme shift into red with a slight oversaturation.
And it's not the issue of the QT Player showing colours different than in FCP - I am aware of that.
Anybody experienced a similar problem?
I still did not find the reason for the weird bahviour of FCPX.
You can see it below on the Pics. The one image is (less saturated, less red) what I see on my viewer.
The reddisch Saturated one is what I see on my external monitor and what I get on export (watching in VLC).
Any idea where this comes from?
