Upload process overview

Whenever you upload a video, Microsoft Stream will automatically encode it into multiple bitrates. As a result, the video will be streamed using adaptive bitrate streaming. This allows Microsoft Stream to optimize the bitrate and quality of the playing video on the fly based on the viewers avaialble bandwidth. For more information, see this topic.

Processing time will vary based on the length and resolution of your video. Your video will be ready to play as soon as possible. We only wait for the 360p version of the video to be ready, not all resolutions. This means you'll get lower resolution playback of your video for a short time while we backfill the rest of the higher quality versions of the video.

We'll send you an email letting you know when your video is done being processed. See email notificatons for more information.


The highest quality encodes take longer, especially if the video is being encoded for high-definition (HD) streaming renditions.

For information about how to upload a file and add things like thumbnails, description, and other metadata, see this topic.


It is recommended to add your videos to one or more channels for discoverability. For more information, see Add videos to a channel.
