Wirecast is a great program for broadcasting in SD or HD, and is capable of multi bit rate broadcasting as using single or multiple camera setups. Wirecast has some great video overlay options and other features which help produce a very professional broadcast.
TWO IMPORTANT NOTES: The item below about matching the bit rate(s) and resolution(s) set in your encoder and your Sunday Streams Manager is a very important step. Skipping this step can cause playback issues. Secondly, the section at the end discussing a local backup is also very important and is highly recommended. For example, if your local internet connection goes down during your service due to weather, the broadcast may not be fully recorded on the Sunday Streams server. Having a complete local backup available to upload in situations like this can be very important.
The first step to use Wirecast is to go to the Wirecast download page to download and install Wirecast. This can be found in the Sunday Streams Manager by clicking Mac Encoders > Wirecast > Download. Once installed, you can get started quickly with the Quick Setup settings. Additional setup details are covered in the short help video below.

Additionally, the bit rate(s) and resolution(s) you use in your encoder must match the bit rate(s) and resolution(s) listed in your Sunday Streams Manager in the Broadcast Settings -> More... -> Bit Rates & Resolution section. The actual broadcast bit rates use must match those listed in the Sunday Streams Manager so that the adaptive bit rate players will function properly. If you are noticing any playback issues, this is a good first place to look to make sure your broadcast encoder settings match those in the Manager.
