Warning

Over the past year, Azure AI Video Indexer (VI) announced the removal of its dependency on Azure Media Services (AMS) due to its retirement. Features adjustments and changes were announced and a migration guide was provided.

The deadline to complete migration was June 30, 2024. VI has extended the update/migrate deadline so you can update your VI account and opt in to the AMS VI asset migration through July 15th, 2024. To use the AMS VI asset migration, you also must extend your AMS account through July. Navigate to your AMS account in the Azure portal and select Click here to extend.

However, after June 30, if you have not updated your VI account, you won't be able to index new videos nor will you be able to play any videos that have not been migrated. If you update your account after June 30, you can resume indexing immediately but you won't be able to play videos indexed before the account update until they are migrated through the AMS VI migration.

Keywords extraction

Keywords extraction use cases

  • Personalization of keywords to match customer interests, for example websites about England posting promotions about English movies or festivals.
  • Deep-searching archives for insights on specific keywords to create feature stories about companies, personas, or technologies, for example by a news agency.
