AMS V3 : Captioning the Video

    Question

  • Hello,

    Adding Subtitles and Captions in Azure Media Services v3 seems to be now available as explained in this link.

    https://docs.microsoft.com/en-us/azure/media-services/latest/media-services-overview

    Where can I find the related sample code/APIs to get this done?

  • Thanks for contacting us. The statement on captions and subtitles should have read as follows:

    • Use Azure Media Services together with Azure Cognitive Services APIs to add subtitles and captions to videos to cater to a broader audience (for example, people with hearing disabilities or people who want to read along in a different language).

    Which means that:

    1. You would use the Audio Analyzer to perform speech-to-text conversion, and generate captions in the spoken language
    2. You could then use Translation APIs to convert the above to subtitles in other languages

    Hope this helps

  • By doing "1" & "2", I will have a transcript file of the speech, but I still won't have a Video with subtitles, right?

    Is there any step "3" thats needed to add subtitles in the video?

    Or, is that not yet possible in v3?

  • Good point. Your steps 3, 4, etc. would be:

    3. Encode the original video with a suitable Transform (see this article), but pause before the "Get a Streaming Locator" step

    4. Copy the VTT, TTML files etc. to the same output Asset as the output of the encoding Job above

    5. Now get a streaming locator

    6. See these examples of how the player can then be updated to play back the captions/subtitles
