Tune for lower latency or higher quality before sharing starts.
Speed mode prefers H.264, keeps frame rate stable, and applies the settings the next time sharing starts.
Audio only mode tunes the microphone broadcast for speech or music and applies the settings the next time sharing starts.
A quick guide before you go live.
Start with Create link. This creates a persistent viewer URL that you can share right away, even before the stream is live.
Set your optional password and adjust advanced settings before creating the link, because those choices apply to that session setup.
The panel on the right always shows your live preview. If sharing has not started yet, viewers will only see an upcoming session state.
Click Start Shareing, choose the screen, app, window, or tab you want to present, and enable audio in the browser share dialog if you want sound included.
Use Pause Shareing to temporarily hold the stream. Use Stop Shareing when you want to switch to another app, window, or screen, then start again. The same viewer link stays active and the stream resumes as soon as the new share begins.
Please use this setup with care: ScreenShare runs peer-to-peer over WebRTC, so every viewer receives an individual stream from the host. It works well for smaller groups, but we do not recommend it for audiences above roughly 30 people, depending on host performance and internet bandwidth. For larger audiences, use YouTube Live or Vimeo Live instead. Those platforms scale better through delivery networks, but usually with higher latency.
