Ye, my point is today's Transformer based models which relies on One-shot learning can actually automate all of the above steps from a product prespective. Today, The downside is the compute units (which would require a lot of brute force). The other concern is it might not be as creative as we want it to be which stems into further problems like 1- Generic content after a point of time. 2- copyright issues.

what might it actually do is speed up the pre production process by atleast 6x-12x time(Considering approvals and reviews by human reviewers).

But this could be a kickass use case for short video on youtube and other video sharing platforms and content creators who need content, sell content for easy bucks.
