Change uploader name?

I hope this hasn't been asked before, I couldn't find it in the search.

Is it possible to change the uploader name after the video has been added to the script? I uploaded some videos via the import folder for test purposes, deleted them again, but then decided to keep them after all, so I clicked on "process queue" and converted them again... only they were added to the script without an uploade name. Is it possible to add or change the uploader name in the admin panel or do I need to check the database?

You'll need to change it from the database as you cannot change it from the admin panel.
