How to Use Wirecast and OBS Studio with Multiple Video Sources

Did you know that it was possible to live stream from multiple sources at once?

In this tutorial, we will cover how to use multiple video sources on OBS Studio and Wirecast. The same process can apply to most video encoders around.

What is an Encoder?

Before we get into the nitty-gritty of setting up multiple sources for your lives stream, we are going to touch upon encoding.

Encoding is a process used to convert the RAW video files captured by a camera into digital files suitable for live streaming over the internet.

OBS Studio and Wirecast are two examples of software encoders that are used for live streaming. This means that the encoder feeds digital video files to the streaming platform in real-time.

The following encoder settings are required for live streaming with Dacast, regardless of your selected resolution and bitrate:
