When you choose to stream your event to Facebook, an important factor to consider is the length of your broadcast. This will impact how you configure your settings.
By default, Facebook has a time limit of four (4) hours per livestream. This means that if you are live for more than four hours, your stream will be cut off and will post as a video-on-demand (VOD).
If you anticipate that your event will last for longer than 4 hours, such as a telethon or a conference, you can do the following:
Navigate to the More Options > Settings menu.
Tap Live Streaming Destinations.
At the bottom of the screen is the option for Continuous Streaming.
Toggling this settings on will allow your stream to stay live for a long of time.
When you turn on Continuous Streaming, your VOD will not save on your Facebook timeline. It can save on your microSD card provided there is enough space available.
If saving VODs on your timeline is essential to your event, the other option is to turn Continuous Streaming off, and manually stop and restart your broadcast. When a broadcast ends, the 4-hour limit refreshes and you can go live again for another four hours without losing your VODs.
