video stream of updating newsboat to 2.20.1

video stream of updating newsboat to 2.20.1

As I mentioned in other places online, I thought it would be nice to try
recording some of my workflow with guix. The video is quite long, an
hour and 20 minutes, and it goes through updating newsboat from 2.13 to
2.20.1 with the change to the cargo-build-system. The audio quality
isn't amazing, I definitely need a better mic, but it was fun and I'd
definitely consider doing it again.

I used simplescreenrecorder for recording, which worked really well. I'm
open to suggestions for encoding flags, the raw video was 1.2GB and
dropped to ~300MB after encoding it for streaming to mp4. I have a
feeling I could do better for size.

I tested the video using VLC on my phone on data, and it started playing
without downloading the whole thing, so it looks like I got the flag
correct for creating a streamable mp4. I'm still encoding it also with
vp9 for a webm but it looks like it's going to be about the same size.

Thanks for doing this!  I've got some videos* of me creating guix
patches for the cookbook.  It's nice to see a more competent developer
share their work flow!
