Automated Video Capture (Server Side)

Good Afternoon

I am looking into using Unity as a basis for creating pre-rendered videos between 30 and 60 FPS on the fly so that they can be viewed on low power devices such as Phones and Tablets as part of a project for a client.

The rendered video will either be dumped to an S3 bucket to be served up in a video player.

The application will take an array of input parameters, render a unique scene between 1 and 3 minutes based on some control logic within the unity application.

Firstly I would like to establish if Unity can accomplish this out of the box or whether additional plugins will need to be purchased and/or developed?

I realise my second question has no definitive answer but a pointer to some benchmarking would be ideal, rendering videos requires a considerable amount of processing power and speed of rendering these videos is vital, as in the client needs a 1 minute video rendered (in the cloud) and pushed to a S3 bucket in under 2 minutes.

Can anyone give me an indication of how much processing power is likely to be needed to make this possible?

Thanks in advance for any assistance.
