Help page question: Unverified credits

The IMDbPro filmography includes an option to add unverified credits in certain categories, listed here:

• Manage your filmography

Comedy

Commercials

Dance

Hosting

Industrial

Infomercial

Internet

Modeling

Music

Print

Theater

Voice Over

Are there any further definitions of these categories?

As some credits for hosts or music or voice-overs may be eligible as verified credits, I think it may be helpful to describe in the help page what kind of credits should be added as unverified.

Does "Voice Over" include foreign language dubbing work?
