Live Streaming Video｜SmartSTREAM Startup Guide

Create a Profile

Create a profile for live streaming via Home > Profile > Create Profile.
Configure video quality and format settings when converting common video files (.mp4, .mov) into file formats suitable for streaming.

A profile is a collection of initial settings such as video resolution and format, and must be created separately for live streaming and on-demand streaming. Here, we explain the procedure for creating a profile for live streaming.

Video Bitrate (bps)	Specify the video quality. The unit is bps. Higher values allow for higher-quality video, but if the viewer’s network connection is slow—such as on a mobile network—smooth playback may not be possible.

Audio Bitrate (bps)	Specify the audio bitrate.	96000
Audio Sampling Rate (Hz)	Specify the audio sampling rate. The sampling rate is the number of samples per second. Higher values improve audio quality but increase file size.	48000
