How to Use vMix Streaming with Dacast
vMix offers a variety of products that are centered around video production.
This particular guide is focused on their Windows-only encoder: the vMix Live Production Software. For this tutorial, we are using version 24 of the software. To ensure your live streaming setup is compatible, check out our post on the minimum vMix system requirements.
What is an Encoder?
Video 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.
vMix is an example of a software encoder that is used for live streaming. This means that the encoder feeds digital video files to the streaming platform in real-time.
vMix offers a powerful encoder with many options. It’s particularly efficient at streaming with lower consumption of CPU power. This capability is noteworthy, as many encoders often monopolize available resources when you use them on a laptop or a desktop.
One of the unique aspects of vMix is that it makes it possible to stream to up to three destinations at the same time.
You can use vMix to encode live events, such as webinars, company-wide meetings, and podcasts.
Required Encoder Settings
|H.264 (x264 may work)
|25 or 30
|3 secs (or 3x frame rate)
|AUDIO SAMPLE RATE
|48 kHz (48,000 Hz)
Before to begin we invite you to take a look at the following encoder settings recommendations for live streaming with Dacast.
Get Started with vMix: Adding Inputs
If you haven’t already, start by downloading vMix. To download vMix, click here. Next, launch the vMix program. You should see a basic layout that looks like this:
To do this, click the ADD INPUT button located toward the bottom of your screen in this layout:
Keep in mind that you’ll need to manually set the resolution to one that your camera supports. Sometimes these settings are auto-detected, but not always. Luckily, the encoder will tell you if it is not set up properly.
For example, if you select an HD resolution on a built-in webcam, you will get an error message like this:
From here, return to the main layout. You can click to add more inputs at this time if needed. vMix is set up to make it easy to change sources. For example, broadcasters can quickly transition from live streaming to previously recorded video.
There is also a switch, located in the center below the Zoom and FTB buttons. This feature allows you to switch between these areas. For example, want to switch to the Green Check above? Click the switch (the slider) to do so. Besides, above the green check, you will see alternate transition options. You can access these options to employ a specific effect in your transition.
Configuring Streaming Settings
Once you have set up your input, you need to configure your stream. This will establish your eventual destination, in this case streaming live content via the internet. To do this, first, click the gear icon found to the left of the word STREAM located at the bottom of the layout.
