Very dark video?

Hi.. first post on fcp.co. Fab site.
I expect many people are spending sleepless nights trying to figure FCP X out.
I sort of like it, never really used iMovie.
Can't figure out why my clips look OK as far as I can tell but the clip displayed in the viewr (large window on right) is several stops darker, really dark.
When I select a clip and scrub through it the clip goes dark and as I said the video in the viewer is also dar. Done some outputting just as a Quicktime mov file and the video plays fine in Quicktime it's just that the video clips playing in FCP X are so so dark.
Any ideas?

thanks.

i read somewhere about the auto correction (color) not doing its job oke.
maybe....

Think I've sorted it. Not satisfactory though!
It is a color management problem. I use a ColorMunki calibration device on my monitor to get some sort of consistency and it seems that FCP X doesn't like the profile that ColorMunki creates. Try going into System Pref's and go to displays and select color then swithch profile to one of the Apple profiles and I reckon it will sort it out.
Not satisfactory because most people want to use calibrated monitors in their workflow.

I don't think this is the problem. I'm having the same trouble as you, but using the default (uncalibrated) profile, and I still have the same issue. Here's what it looks like.



It almost looks like the green channel is being removed completely. Very strange... any ideas?

I had the same problem and asked some people (like Izzy) They told me: it's a bug.
after updating to 10.01 the problem was over.
