When you distribute your music videos to Vevo, they will display your videos on YouTube under your own Vevo channel. If this is your first ever music video, this Vevo specific artist channel is generated with your first video submission on DistroVid (more info on that here and here).
This Vevo channel is completely separate from your YouTube Music provided Topic Channel or YouTube Official Artist Channel, and it's exclusively used to list only your official Vevo Music Videos. Your Vevo channel won't display your own personal YouTube videos or YouTube Music Art Tracks.
That being said, it is possible to have your Vevo videos listed on your existing Official Artist Channel!
When you link the two channels, your Vevo videos will be listed directly on your Official Artist Channel, in addition to your Vevo channel. You can also see stats for your Vevo content directly through your YouTube Creator Dashboard when logged into your Official Artist Channel.
