Is it possible to upload a movie as a featured image? May it be linked from my portfolio from youtube? Movies are quite heavy and I’m not sure I could upload them to media gallery.
I hope you are well today and thank you for your question.
To achieve this you have to develop custom code in the child theme of Activello theme.
Developing custom code for custom functionality is beyond the scope of support that we provide here.
If you are not a developer then you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. Colorlib recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5

No, such thing is not possible without a major customization or third party plugin
