Script that captures viewport progress during a project for the creation of "work in progress" timelapse.

Hello guys.
I did a search for a tool to capture viewport progress during a project, but I find the available scripts quite limited.

In short... the idea I have is for a script that would use a camera (preferably a hidden camera, not used in any of the available viewports) to grab screenshot previews and save them to a selected folder. It could capture on mouse clicks and keyboard presses, but not FPS as this would result in very large quantity of images. What I would like to achieve is a fast timelapse video of a project that would probably take 100 hours or so.

Additional features could be the use of more than one camera.

Thanks for reading and if anyone could help, please do.
Thanks again : )
