Need help creating best quality flv files

I shot some products shots of a model doing a 360. It’s a simple 10 second clip. In final cut - the video looks great. i export it as a mov file and that looks great. I’m using the adobe media creator to make the flv files - but I can’t seem to get the files to look good enough. it’s always a bit faded and not nearly as clear.

and tips would be appreciated!

thanks
