So, something this site and other similar sites have is a lot of Intro to Worship or Prelude Videos or Sermon Series videos that are mostly focused on specifics themes such as Holidays or Seasons.
I would love to see more "Mini Movies" that are just generic worship intro videos. With topics like just proclaiming the Psalms or to "rest and let God be God" or "Come, Let Us Worship and Bow Down".
We use these primarily as the worship team is getting up on stage and picking up instruments/moving mics into place, etc. as a transition between pre-service and the start of worship.
I'd be happy to give more specific ideas if needed.
