Unfortunately, with VEVO, there is no username or login available to anyone, we don't even have one. Think about it more like iTunes and distribution rather than YouTube in the way that no one has an iTunes login to upload content. VEVO (and the feed to the YouTube@VEVO account) is manually created and updated by their staff, which is why the initial turn around time is long. Any changes you may have (photo, video description, additional videos, etc.) please fill out a support ticket to notify us.
