How to Live Stream to Multiple Destinations with Wirecast

Already live streaming? Why not stream to multiple destinations (and record) all at once? Streaming to multiple destinations is an effortless way to grow your audience, expand your reach and number of views. Wirecast can easily be configured to stream to multiple destinations and record simultaneously.

But a word of caution before you start. More destinations equal more processing power and more upload speed. So, you’ll want to make sure your hardware and network speeds can handle the extra demand of streaming to multiple destinations. Because if your setup can’t handle the stream, high CPU usage will create dropped frames (choppy video), macroblocking or audio-video sync issues.

To determine if your bandwidth will handle your stream:

  1. Open Wirecast and go to Output Settings, add the bitrate from all of your desired streaming locations and multiply that sum by two. This is the size of your simulcast.
  2. Test your internet connect at
  3. To ensure a high-quality stream, your internet speed should never be less than 2X the size of your stream

Now that you’ve tested your bandwidth and stream size, you’re ready to stream to multiple destinations! Just follow these simple steps to configure your streams and begin simulcasting:

1. Configure your output settings

Open Wirecast, click on the Output Menu, and select Output settings. Pick your primary streaming destination and name your live stream. If your destination requires authentication, enter your credentials at this time.

2. Add your streaming destinations

Add additional streaming destinations as needed. Note, if Facebook Live is one of your streaming destinations – you’ll need to add either Facebook Live OR all your other destinations as an RTMP Server. This is because Facebook does not allow anyone to stream to Facebook Live and other pre-configured destinations at once. So, either Facebook Live or all the other destinations must be added as an RTMP Server.

To stream to a destination as a RTMP Server simply:

  1. Open Wirecast and go to your Output settings. Select RTMP Server in the Destination dropdown menu
  2. Enter the unique RTMP Server Address (The ingest URL for server or CDN you are sending your stream to) in the Address section. **Typically RTMP information can be found when scheduling your stream or in the stream management console
  3. Next, enter the Stream Key (an alphanumeric code for a specific channel or event you’re streaming to) under Stream

3. Manage destinations

Now you’re ready to begin live streaming! Click the Stream and/or Record button in Wirecast or use the check boxes left of the output settings menu to toggle between your preset destinations.

        Yes, good question! The short answer is if you use the exact same presets on your output destinations, it won’t use as much of the CPU as using two different presets. It will reuse the same encoder.
        So you may ask: is the preset called “Facebook: 720p30 (4Mbps) x264 H.264” the same as the RTMP Server Preset called “Default: 720p30 (4Mbps) x264 H.264”?

        Even though the settings are all the same in these two presets, they are NOT considered the same preset. Under the hood, each preset gets a unique identifier – so unless you are using the exact same preset, Wirecast will treat it as a different encoder.

        So, to make sure you’re using the same preset for your encoding (and record to disks!), you need to create a new custom preset and use that one in all your encodes. To do that, go to any output settings panel, and click the Gear Icon next to the Encoding drop down. From the Gear menu, choose “New Preset” – set your settings, and name it. Then you can choose this custom preset for all your encodes.
        Hope that helps!

      I’m assuming you meant you want to INGEST eight RTSP (webstream) sources into Wirecast (since we don’t output RTSP from Wirecast). If that’s the case, Wirecast handles those pretty well, (it might actually be harder on your network, actually). But our recommended processors (Intel i7 quad-core @ 2.8GHz+, 6th generation3 or higher) should be sufficient.
