Closed Caption .vtt edit in Stream

Love the closed caption creation on upload but how do I edit the .Vtt file created to correct our acronyms and accent? TIA

    So it would be as follows...
    - After the autogenerated caption file is created and shows the transcript mode on the video.
    - Edit the video
    - Options section > Captions > "Download file"
    - Open up the .VTT file downloaded in a text editor, make corrections, etc.
    - Go back and edit the video > Options > Captions
    - Uncheck the "autogenerate a caption file" check box.
    - "Upload a caption" file button.
    - Upload your edited .VTT file.
     
    We'll then use your new custom caption file for the transcript mode and deep search.
     
    NOTE: We'll be adding ability to edit the transcript direclty in Stream in the future as I know the above isn't intuitive or easy.

I did search for a .vtt file editor and found a free one called 'subtitle edit' very professional and really easy to use

    When attempting to upload a .vtt file on Mac OS X I get the following: "File format not supported. Please select a .vtt file" Something to do with how OS X handles files/extensions? Could Stream connect with Office 365 instead of using the upload dialog?

      I'm getting the same error as David Van Leeuwen today - using a Mac, have been diligently editing a downloaded caption file, and cannot upload it.

       

      Even downloading the caption file from Stream, and then immediately trying to reload it, fails as "File format not supported. Please select a .vtt file" - and that's the file directly from Microsoft Stream!

       

      I've tried uploading the file from OneDrive rather than from my hard drive to no luck. Any workaround? Or is the workaround to find someone use a Windows PC?

       

      (This is the second irritation today when trying to use Stream - both https://support.microsoft.com/en-us/office/edit-the-transcript-of-a-meeting-recording-in-teams-2f461386-e39a-4444-b9e2-5787da1da11b and https://docs.microsoft.com/en-us/stream/portal-add-subtitles-captions for how to get to the captions area don't match my view of stream - neither ... has "Edit video" and the pencil does not have "Update video details" - fortunately one of the ... has "Update video details" so I got there in the end.)

        scottkeir I have found a way to make the .vtt file work in Stream by simplifying the code produced by stream in it's auto transcript process. The original .vtt will look like this:

         

        WEBVTT

         

        NOTE duration:"00:04:19.8340000"

         

        NOTE language:en-us

         

        NOTE Confidence: 0.926972687244415

        In order to make these work they need to be simplified by removing the "NOTE Confidence:..." lines and changing the verse numbers to sequential numbers:

         

        WEBVTT

         

        NOTE duration:"00:04:19.8340000"

         

        NOTE language:en-us

        When simplified this way the resulting .vtt file can be uploaded back to Stream.

         

        Here is also a handy page that strips all of the code and gives you a flat versified text:

        docs.microsoft.com

      I just opened a bug to track this issue. I don't have a mac to test and see if I get the same issue.
