I'm attempting to get my festivids vid into FLV format that is under 50MB and can't seem to accomplish it without the vid looking like crap.

I'm using ffmpegX - which is an application I've only used once (to format for a con vid, so for totally different purpose).

Does anyone have any pointers?
I normally export from FCE to *.mov format and use MPEG Streamclip to make *.mp4 (or *.avi) and don't see a *.flv option in MPEG Streamclip but maybe I'm missing something simple
