This depends on what you are displaying. If you are displaying road maps, then having the maps copyrights appear is all that is needed. If displaying satellite/aerial imagery, things get a bit more complicated. The service license terms for Azure Maps are here: https://www.microsoft.com/licensing/terms/productoffering/MicrosoftAzure/MOSA#:~:text=linkid%3D874330.-,Azure,-Maps see the imagery section. If the imagery is from Airbus, there is some restrictions on where the users viewing the imagery can be located (Airbus doesn't let certain countries access their imagery). If the imagery is from someone else (Bing Maps provides additional imagery to Azure Maps from other providers such as Vexcel), the Bing Maps terms of use would apply: https://www.microsoft.com/en-us/maps/product/enduserterms With those terms there is different restrictions if birds eye imagery is used. That said, I suspect your use case would fall under the Bing Maps Media & Broadcast terms as those cover video: https://www.microsoft.com/en-us/maps/product/broadcast-terms
