No, I've traditionally made either a full quality AVI and then an MOV through MPEG Streamclip, because that's always deinterlaced things one final time and smoothed out the credits text. But this time I went straight from FCP to .mov, and then tried to use MPEG Streamclip to create a web file. Nothing comes out well. What do you choose as your final output in VisualHub? I don't know anything about the program but I'm always willing to try something new.
