Is there a way to update the thumbnail for a video in Azure Video Indexer? It looks like it randomly assigns a default thumbnail for the video that is uploaded - Looking for a way to update it either from Video Indexer UI or via an API. Thanks!
the thumbnail you see in the right pane (in the character list) is called "best face" thumbnail, there is no API in which you can change the thumbnail to a different one.
if you rename the character you will be able to see all the thumbnails that is related to this character under customization page in people tab VideoIndexer Customization
there you can delete thumbnail of the character (but even this will not change the "best face")
