Hello @Ahmed Fathy , Thanks for using Microsoft Q&A Platform.
Make sure you have an Azure AI Video Indexer account connected to an Azure OpenAI account. Azure AI Video Indexer is unable to connect to fine-tuned models.
Do you have an OpenAI access? Otherwise, you can apply for access to Azure OpenAI by completing the form.
If you still face issues, please try to upgrade to standard pricing tier and try once again.
Regards,
Vasavi
