You can use z-o-o-m File & Image Uploader
with this soft you can upload mutliples videos to youtube & other video/image/file hoster
work on windows , for use in linux you need to use wine & playonlinux
I prefer http://z-o-o-m.eu
Desktop client that let's me upload to multiup with reusable uploads along with like 700 other hosts.
That way I get all my favorite hosts but don't have to use the browser like zippyshare, mega, gdrive, 1fischier, openload etc etc.
