I've started doing this more. The videos of my work has always outlasted the work itself. Even though technically I can dig up old compilers or try and update my dependencies, I rarely do. So whatever was captured in the video becomes the only artifact of my older programming projects.

I used to think that video formats would no longer be supported over time, but even the oldest weird video formats still play in VLC and MPC, and probably would work fine if uploaded on YouTube.
