Production studio workflow

As shown in the figure, the complete workflow of using a production studio includes the following stages:

Live stream settings: Use the production studio console to configure features such as the streaming domain name, output definition, transcoding, and recording.
Live stream configuration: Add audio and video sources and set the output screen layout.
Start live streaming: When the stream starts, the mixed stream is output to the Preview (PVW) area. The Program (PGM) area is used to output the final live stream.
Real-time production: During production, use features such as real-time captions, graphic overlays, and the audio mixer to adjust the live content and program effects.
