It seems that "emotion" and "emotion" are likely to be empty for black and white videos.

I use two black and white video which full of emotions to test. However, "emotions" and "sentiments" of videos are empty. (you can find these vedio on https://www.youtube.com/results?search_query=The+7+basic+emotions and https://www.youtube.com/watch?v=tiicx0d7yBg)

    Thank you for reaching out. Video Indexer detects emotions based on speech content and voice tonality. It doesn't rely on facial expressions. Please refer to this blog formore information: https://azure.microsoft.com/en-us/blog/cross-channel-emotion-analysis-in-microsoft-video-indexer/ And, VI documentation: https://docs.microsoft.com/en-us/azure/media-services/video-indexer/video-indexer-overview Thanks.
