Unfortunately Doug is dead on on this one. I worked at a news station that lingered on SD longer than they should have and while some of my favorite news feature shooting was done there It is utterly useless.The best export option is really dictated by your timeline. Hopefully you are editing on an HD timeline, and if so, then export with one of Media Encoder's Vimeo presets.
But if you want some further advice, throw out all the SD stuff and start over. Nobody, I mean nobody, wants to see your SD stuff.
