@Yuji Tomita (JP) To answer your question, I found couple of FAQs from Azure AI VI documentation.
Are video and audio files indexed by Azure AI Video Indexer stored? Yes, unless you delete the file from Azure AI Video Indexer, either using the Azure AI Video Indexer website or API, your video and audio files are stored. For the trial, the video and audio files that you index are stored in the Azure region East US. Otherwise, your video and audio files are stored in the storage account of your Azure subscription. Where does Azure AI Video Indexer store customer data? By default, your data is replicated to the paired region into which you deployed the Azure AI Video Indexer instance. For region with data residency requirements, your data is always kept within the same region. For more related information, check out other Privacy Questions in this section.
So, if you have used paid account the data should be in the same region as your AI VI resource. There are only two exceptions here applicable to Singapore and Brazil South regions.
Is the content indexed by Video Indexer kept within the Azure region where I am using Video Indexer? Yes, the content and its insights are kept within the Azure region (except for Singapore and Brazil South regions) unless you have a manual configuration in your Azure subscription that uses multiple Azure regions.
By default, all regions in Azure are paired for BCDR reasons and AI VI also follows this. Customer data in a region is replicated for BCDR reasons to the paired region i.e in the same geographical region.
I hope this answers your question. Thanks!!
