Microsoft plans to start removing the automatically-generated transcript of some Stream videos in September 2021. Only automatic transcripts are affected, and only if no one is looking at the video. If you’ve taken the time to edit a transcript or upload a manual transcript, Stream will leave these transcripts alone. It’s all part of the big plan to get Stream off its own Azure storage and onto SharePoint Online and OneDrive for Business.
Teams gives Office 365 tenants the option to store meeting recordings in Stream or OneDrive for Business (including SharePoint Online). Now configurable through Teams meeting policies, new meeting recordings are dealt with like any other file, meaning that you can share recordings, apply labels, update metadata, and so on.
