Permissions
In the permissions section, you can control who can see your video, who can own and edit it, and which groups and channels it’s displayed in.
See this article for more in-depth information on video permissions.
Allow everyone in your company to view this video
When checked everyone in your organization can see the video and is able to add it to their groups and channels. This, in effect, makes your video available for viewing companywide. To be able to add a video to a companywide channel, this check box must be checked.
When not checked, your video will only be viewable by those people and groups you've made viewers.
Shared with
Use the Shared with drop down to narrow your search scope and pick who you want to share your video with.
Groups - search scope to add your video to a group that you can contribute to.
Channels - search scope to add your video to a channel directly, including companywide channels.
People - search scope to grant permission to individual people, AD Security Groups, and/or Microsoft 365 Groups that you don't have contribute rights to.
Any person or group added will automatically be granted view permission to your video. If you want any of these Viewers to also be able to update your video, check the box next to their entry in the Owner column to upgrade their permission.
The Display check box shows up for groups where you are a contributor. This controls if the video shows up in the group's pages in Stream. If it's not checked it means that the group has access if you send them a link or they found the video in search, but it won't show up on their group's pages directly.
For more information about permissions, see Video permissions.
Options
In the Options section, you can control various settings for the video.
Comments
If you don't want users to be able to add comments directly on the video player page, set Comments to Off.
Captions
Closed captions are a text version, in the original language, of what's spoken in the video. When a video has a caption set, viewers can click the CC button on the player while watching a video to show the captions under the video.
If you've selected a supported Video language in the Details pane for the video, then the Autogenerate a caption file check box will be checked. This means a caption file will be automatically generated. In addition, people with the correct license will be able to discover your video based on the text in this transcript or your own uploaded closed caption file.
If you deselect the box, Autogenerate a caption file, then you can upload your own closed caption file in the WebVTT format.
