      Learning how to broadcast your screen with microphone audio via Wirecast may be a bit more complex than expected. However, there is no need to fret. We’ve put together a step-by-step guide to walk you through the process. If you follow these steps and still need further support, let us know.

      What is Video Encoding?

      Before we dive into the ins and outs of using Wirecast to capture audio, we’re going to briefly discuss encoding. Encoding is a process used to convert the RAW video files captured by a camera into digital files suitable for live streaming on your website over the internet. Wirecast 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.

      Required Encoder Settings

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

      VIDEO CODEC H.264 (x264 may work)
      FRAME RATE 25 or 30
      KEYFRAME INTERVAL 2 secs (or 2x frame rate)
      SCANNING Progressive
      ENCODING BITRATE Constant (CBR)
      AUDIO CODEC AAC
      AUDIO BITRATE 128 kbps
      AUDIO CHANNELS 2 (Stereo)
      AUDIO SAMPLE RATE 48 kHz (48,000 Hz)
