Question about Adobe Premiere Pro

[elmergantry]

So I'm using Adobe Premiere Pro on my MacBook Pro with Lion. I have an Intel Core Duo Processor and 16 Gigs of ram. On Premiere Pro I have the preview screen set to maximum render quality.
When I export the AMV to a .mov to check it for anything that I need to change, it doesn't look nearly the same as in the preview. I have many scenes with multiple shots over each other with the bottom shot at 100% opacity and the others have rising opacity. This makes the shots come in very subtly, especially the 6-7 second seconds of rising from 0-50% opacity. However, once I export the movie the subtlety is gone. The shots appear much more opaque and it breaks the flow.
How can I make my exported video look like the video preview?

Never mind. I did it again and it worked. Don't know why though.
