Live events in Microsoft Stream (preview)

You can now create live events using Microsoft Stream across the organization. Live events enable producers to curate and control the content that is broadcast to an audience. Now you can schedule, produce and deliver live events more effectively for a variety of scenarios like companywide events, leadership updates and more.

With this workflow, you can create, schedule and run live events using a single bitrate RTMP or RTMPS stream from an encoder – we’ll take care of all the transcoding for adaptive bitrate delivery to your viewers. Just like any other video in Microsoft Stream, you can make the live event open to your entire company or limit the access to specific groups or people. This provides an end-to-end creation and viewing experience inside of Stream.

After the event, in the video on demand, with intelligent features including:

  • Speaker timeline uses face detection to identify who is talking, so you can easily jump to a particular speaker in the recording.
  • Speech-to-text and closed captions
  • Transcript search and timecodes let you quickly find moments that matter in a video.

Live events in Microsoft 365

You can create a live event in Microsoft Stream, Microsoft Teams or Yammer—wherever your audience, team, or community resides. Attendees can participate in real time, with high-definition (HD) video and interactive discussion, or catch up later with powerful AI features that unlock the content of the event recording. Seamless integration across Office 365 means that you can use Stream to deliver highly produced, studio-quality events. Learn more about live events in Microsoft 365
