MS Video Indexer Transcript Issue - Good quality at the beginning of the video, but poor quality from a certain point RRS feed

  • Question

  • I'm trying to use MS Video Indexer ( to generate transcript/subtitle in Brazilian portuguese for a video set, but I'm getting poor quality transcript from a certain point of video.

    I mean... It starts by transcribing well in the first few minutes of the video, but from a certain point the generated transcript becomes meaningless or generates no transcription.

    IMPORTANT: the media that I'm testing has good audio quality.

    I already tried both to set the language of media as 'pt-BR' or to use the language autodetect function. Both produced the same bad result.

    Example of part of bad transcription:

  • I'd suggest opening a support request so that we can investigate the specific scenario and file.

  • Hi,

    Thanks for reaching out!

    A new pt-BR model is planned to be released in the coming weeks and should improve on the issue you are reporting.

    Additionally, would be great if you could share example files with us so we can look into the specific degradation in quality that you report. Please send the files to

  • Hi!

    Thanks for your reply!

    When will this new pt-Br model be available? Is there a release date scheduled? Because I have a set of videos that I want to process with Video Indexer for an event that will happen at the end of this month.
