There are two main components for broadcasting or saving to disk.
Encoder Preset - You need to decide how you are going to encode the broadcast
This means what type of compression you'll use - say JPEG or MPEG4, etc.
Wirecast comes configured with many common encoding styles.
For now, just select one of these defaults.
Destination - You need to decide the destination of the broadcast
Will you save it to disk? Will you send it to a server to be reflected to your users?
Broadcast Settings
Select "Broadcast Settings" from the "Broadcast" menu (or Command-Y).
Here's the window you'll get:
The top part of the window is where you can add multiple settings for the same broadcast.
You might use this to create a broadcast with many bit-rates (for users who may be on different internet connections). You might also use this to record to disk as the same time as you create your presentation.
The "Encoder Preset" popup defines how your broadcast will be encoded (what "codec" to use). We have put some sample ones in here. For now, let's just use the default.
NOTE: If you want higher quality output, choose any encoder preset that includes "LAN" (Local Area Network).
At this point, you're ready to configure the destination.
