Do you have Sorenson Squeeze or Adobe Media Encoder? If so, export a self-contained QT file from FCP using Current Settings (not using QT Conversion). Use that file in Squeeze or Media Encoder. Do use the On2VP6 codec and choose a data rate between 500 and 1000kbps. The higher the better the quality. However, unless viewers have robust connections they may have problems with 1000kbps. Set your audio bit rate to 96kbps stereo for decent audio. If it’s mono, 48kbps will do. Set the video to bring the total bit rate to where you want it.
You can also do this with Compressor. Using the same exported file in Compressor, make an H.264 file with similar settings above. Of course, you don’t use VP6 as you’re using H.264. After the file is encoded change the .mov extension to .flv and you’re set.
