Video owners and Stream (Classic) admins can upload a new version of a video, without changing the link to the video, embed codes, or video details and permissions.

The following information related to the video is kept from the previous version:

  • Details (Name, Description, Video Language)
  • Permissions
  • Options (Comments)
  • History of Views, Comments, and Likes

The following information from the previous version of the video is not kept:

  • Thumbnails. Any custom thumbnails are removed, and new thumbnails are generated.
  • Forms. Though the form itself is still in Microsoft Forms, you'll need to open the new version after it is uploaded to Stream (Classic) and put each form in the correct location in the video.
  • Transcript. Any edited or custom uploaded caption and subtitle files are removed, and a new transcript is generated when the new version of the video is loaded.
