When you upload a video from your device to Microsoft Stream, captions are generated automatically. Speech recognition isn't perfect, so the captions may have mistakes for the video owner to correct. Before you start, consider reviewing best practices for captioning from the Described Caption and Media Program (DCMP).

Editing automatic captions for accuracy

1. To edit captions on your own videos, log in to Microsoft Stream.
   
   
2. Select My content > Videos.
   
   
   
   
3. Your videos appear as a list. Select the video you want to caption edit.
   
   
   
   
4. The video page loads with the captions appearing in the Transcript pane on the right. From the Transcript pane, click or tap the pencil icon in the upper right to start editing the captions.
   
   
   
   
5. Click or tap any caption line in the Transcript pane requiring an edit. In this example, the second caption is selected and becomes editable. The text "Hail All my Mater" can be edited to "Hail Alma Mater."
   
   
   
   
6. Use the replay icon — a triangular play button surrounded by a circular reverse arrow — to listen to the caption again. Confirm you have accurately transcribed the caption. 
   
   
7. To make the caption change, click or tap Save. To undo your edit, click or tap Discard.
   
   
   
   
8. Once the edit is saved, Stream will display "Changes saved."
   
   
   
   

   If you need to edit the same caption again:

   After you save a caption, the just-saved text appears to remain editable. But it's not. If you need to re-edit that caption, click or tap the caption above or below without making changes. Then select the original caption to re-enter edit mode to make and save the additional change.

9. When finished caption editing, click or tap the checkmark icon in the upper right of the Transcription pane to switch from edit transcript to view transcript.
   
   

Downloading the captions file

2. The video details page appears. Under the Options pane and in the Captions section, click or tap the Download file link.
