A big benefit of going LIVE to Facebook is to have real time one-on-one conversations with those in the chat.
The good news is that pre-recorded LIVE videos don't have to remove that element from your recordings.
For example: If you're church is consistently going LIVE on Sundays, you can include your congregation by having someone else film themselves saying opening prayer. You can ask for volunteers to film themselves for 3-5 minutes and share their small spiritual stories and thoughts. When editing these together you can create a whole different kind of show.
Another example: If you're filming a LIVE Q&A video, then you can add some pre-written Q&A cards or have your audience submit questions ahead of time (via video or written!)
While your final pre-recorded video is LIVE, you can encourage everyone watching to chat together in the comments section and answer questions.
