FCPX export-bad results, need your help

[Piranha]

Guys, I just switched to FCPX and found that I do something wrong with export of final movie
I edited my 2.7K footage add some color correction and than share master file in 2.7k, result is disappointing totally
picture is unsharp, all details washed out, what I'm doing wrong

Go to Window -> Project Properties (or ⌘J) and set your parameters.
Don't forget that FCPX takes the first imported file as a benchmark for the rest (when you use a low-res intro or picture). But you can adjust that with the above mentioned setting
If it still doesn't work, send me a private message
