music video library

Show us what you’ve done and maybe we can help.

i added a new library categorize Music
i picked my folder library just like my mp3 song i have

A Music library won’t pick up videos unless they are associated with albums/artists.

If you just have stand-alone music videos, you’ll need to choose the “Other Videos” library type.

i’ll try that.
thank you.
