Live streaming overview

Videosync supports several ways to go live, each suited for different production needs. This guide helps you understand the options and choose the right one for your event.

Live Control Room (RTMP from external encoder)

Key features:

• Use professional encoding software or hardware
• Full control over video production, overlays, and mixing
• Manage slides, polls, and chat via the Live Control Room
• Real-time subtitles and chapter indexing
• Manual recording control

Best for: Professional productions, multi-camera setups, or when you need advanced video mixing and overlays.

• Invite remote speakers via a link
• Speaker dial-in and dial-out via phone

Best for: Managing a conference call alongside a professional RTMP stream, or running a standalone conference call event.

• Audience sees it as a live event
