Several weeks ago we started to use TubeMogul and have been really impressed. It's now a part of our daily workflow.

Each morning we upload our 3ivx 270x480 Quicktime file to Tube Moguel, enter 3 fields of metadata (title, descriptions, tags), select a category and then TubeMogul quickly uploads the video to 9 different sites all within a few minutes:

YouTube, Brightcove, Blip, Dailymotion, Revver, Google Video, Metacafe, Myspace and Yahoo.

We have never distributed through any of these sites before mostly because we just haven't had the time to go around uploading all day on top of the 9 different files we serve ourselves.

TubeMogul has been really fast. They also keep track of stats across all the sites so it's very easy to keep tabs on how things are going.
