Finally, a fourth computer runs with an additional copy of vMix in order to receive the main production computer’s output and connects it to the local public television system. Using the vMix remote control connection, an operator can update and change the information in titles that appear in the main production computer. This computer triggers overlays and graphics. A third computer is used to connect directly to the vMix remote controller available via an IP address.

In the example above, you can see a four-computer set-up that broadcasts the morning announcements at an elementary level school. Vmix local area network with NDI A local area network used for school announcements show This helps you swap between NDI® sources and conserve bandwidth and processing power. In fact, when you right-click on an NDI® source, you will see a list of other NDI® sources on your network. Once you have connected to an NDI® source, vMix added a feature to right-click on that NDI® source to choose any of these options on the fly. Finally, Increase Buffer Size is ideal for scenarios where latency is not an issue. The PsF option is a progressive video format like 1080p29.97 or 1080p30. Audio Only mode will allow you to connect to the NDI® source without video. Low Bandwidth Mode is a great option if you are having bandwidth issues on your network. Below the list of available NDI® sources, you can choose to connect with Low Bandwidth Mode, Audio Only, Progressive Segmented Frame ( PsF), or Increase Buffer Size. One area of vMix many users appreciate is the little preview windows that makes it easy to switch between sources. The tool will display NDI® sources with a friendly name, an image, and an IP address when available. A small loading animation will cycle next to the NDI® logo to let you know that vMix is searching for NDI® sources that are available on your local area network (LAN). When you open vMix, click the Add Input option and select the NDI®/Desktop Capture tab to view available NDI® sources on your network. Connecting to the NDI® inputs is fairly simple with vMix.
