Procedure of using a production studio

The preceding figure shows how to use a production studio. The procedure consists of the following steps:

1. Live stream settings: You can configure live stream settings such as the streaming domain, output resolution, transcoding, and recording settings in the production studio.
2. Live streaming configuration: You need to add audio and video materials and configure the output layout.
3. Start of live streaming: You can use PVW to preview mixed streams and use PGM for live streams output.
4. Real-time production: You can use features such as live subtitles, graphic packaging, and audio mixer to configure live streams and adjust effects.

Quick start

   The first time you create a production studio instance and enter the production studio page, the Studio Settings dialog box is displayed. You can also click Live Stream Settings in the upper-right corner of the production studio page to open the Studio Settings dialog box. For more information, see Configure a production instance.

   Note Each account can create up to 50 production studio instances. To create more production studio instances, submit a ticket. For more information, see Contact us.
