Help with "Final Cut Pro"

[alebeau]

Yesterday I watched a video on youtube that explained how to Chromakey with Final Cut Pro. However, I am trying to use the software today, and the changes I make are not working. On the youtube video yesterday, the guy said that I had to get my video (in my case an .MOV file) and add it. Then I added a granite layer. Then I did something with "Proc Amp" and "Levels." Then I used "Blue and Green Screen." Now, as I was doing all of this, there were two screens. I could basically see the video twice. So, after I saw how neat this was...I quit the program without saving anything. Then I wanted to try again. And this time, nothing worked at all. As I moved the options under the control tab, nothing seemed to work. Even when I dragged the things like "Proc Amp" and "Levels" on top of the ".MOV file," nothing happened because when i went under the Control tab, and under "Video", nothing was there. (Before when I did it, the Proc Amp and Level and the other things i added on top of the .MOV file were there....in the order in which I dragged them...)

I would appreciate help if anyone has an idea of what Im speaking off.

Please help...

God Bless...
