How to Set Up a Live Stream Podcast for HD
Live streaming podcasts allow audio and video data to be broadcast to a mass audience via the Internet. Most live-streaming platforms, such as Livestream, provide the content creator with a URL that directs viewers to the creator’s podcast page. Live-streaming platforms support high-definition video and audio as long as the content creator has an HD-capable webcam and microphone. Podcasts recorded and transmitted in HD do require more system resources than standard podcasts.

Set the audio options in your video-streaming software. Live-streaming platforms have an options menu. Click "Options" on the interface followed by the tab for audio settings on the drop-down menu. Select your audio input device and configure recording parameters as needed. Audio options include recording in 8-bit or 16-bit format, in stereo or mono, and choosing from wavelengths ranging from 11.025 kHz to 44.1 kHz.

Set your video recording options in your program’s video options menu. Click “Options” followed by the button for video settings. Select your HD video-input device from the drop-down menu and the video compressor you will use. Most streaming programs set Microsoft Video 1 as the default compressor, but options include Intel IYUV codec and X-Vid MPEG 4 codec. You can adjust the quality of the recording by configuring the packet size, or the amount of data, in bytes, sent at one time. You can also adjust the frame rate, or the frequency that the video-streaming program records frames. The higher the frequency of recorded frames, the more data will be sent in each packet, which affects the streaming rate.
