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

    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.

  • Accuracy of Video Indexer Person recognition based on the Face API

    There is an issue with the Azure Video Indexer person recognition. My company uses the Video Indexer to recognize persons based on the person model. We noticed that if we divide the video into individual frames and use the Face API directly with these frames, the recognition rate for the persons is much higher than if we search for persons with the Video Indexer. That doesn't seem to be right. How does that happen? How exactly does the Video Indexer use the Face API? Which frames are generated? Is the video divided into frames every second? Or is the analysis based solely on the keyframe? As far as I know the Face API works with pictures only. I sincerely hope that you can help me. Thanks for your time!

  • Indexer returns "Breakdown_not_found" errortype

    Hello, as suggested in the microsoft documentation were polling the result from the videoindexer via the api call. sadly since around 2 weeks i noticed that for most of our videos the videoindexer returns the error: {'ErrorType':'BREAKDOWN_NOT_FOUND','Message':'Base video 'xxxx' cannot be found.'}, this is happening on our new deployments and also on older deployments that didnt have this issue in the past. So far i was unable to find any systematic issue for why this is happening, i hope you could give me some insight on the issue. Thansk in advance, Alex

  • Difference between Cognitive service and Video Indexer

    We are currently using Azure Cognitive services to: - track faces in our videos - extract faces and detect age, gender, emotion frame by frame - group faces to "identity" persons in the video (we just need to know that person A appears in frame x, y and z) - detect labels (environment, etc) So I was wondering if Cognitive services is superseded by Video Indexer and only Video Indexer will get all the improvements from now on? Also, if I am supposed to use Video Indexer, can I require just the features I am interested on? E.g I do not need indexing, search, audio transcription and more.
