Needed help on exporting and the perfect camera angle

So I created a Countdown timer using Animation Nodes as a part of a project I am working on currently.
I needed help with Three Things Regarding it.
How to get the perfect camera angle so that I can capture the 3D Text popping out.
How to get the countdown from 2 minutes / 120 seconds without having to render a huge amount of frames.
I created this on a separate blender file and wanted to know how to export The 3D video with the text popping out along with the animation nodes and the material onto my main blender file.

Imgur file with the details required about the project.
Youtube Video from where I created it.

Thanks A Lot in Advance.
