Have you considered using Gource?

As an example, here's a video covering 22 years of the evolution of Python:

Thank you for pointing me to gource, but I wanted to understand it as a general approach which would be a better build it via libffmpeg or opengl.

I'm keen on building something, and extending to other use cases like embedding photographs, milestones and other major events involving our business unit.
