How do I grab subtitles from an MS Stream recording?
Download subtitles or captions
If you have uploaded a subtitle or caption file, or autogenerated a caption file, you can download the WebVTT file from the Update video details page.
If you need to make changes to the autogenerated transcript / caption, you can download the caption file and edit it in a text editor of choice before uploading it back to Stream, or you can edit the transcript directly in Microsoft Stream in the transcript window.
Get just the text from a transcript
At times you may want to get a copy of a video's transcript without any time codes, metadata, and extra lines.
ADD MORE INFO?
Microsoft Stream doesn't have a built in way to do this, but you can download the transcript (as listed above) and use a simple web utility to extract the transcript text from your downloaded VTT file. This web utility allows you to pick VTT files from your computer and get a copy of the text portion of the VTT file containing just the transcript.
