Facebook Live is a great way to run video, but you have no options for a lower 3rd, overlay graphics, watermark or anything else. There are two iOS apps out there that allow you to do that from Wirecast and Teradek. I show you what you have to do to set up the Live from your profile, and then each app.
What You Need for iOS Setup
The common RTMP url is: rtmp://rtmp-api.facebook.com:80/rtmp/
Set up the RTMP security key, if you streaming from a Facebook Page, go to Publishing Tools (top of page) -> Video Library (left of page) -> “+Live” Button (top of page).
If you are trying to stream from your own profile, you will need help with the setup. iag.me set up a button. Get the LINK here.
iOS Apps to accomplish extra options like lower 3rds
Both of these programs will allow you to create a more enriched video environment with graphics, scenes, title cards and more.
