Size 720x400 on a 80x25 terminal (tmux within wsvt25), transcoded to MPEG-4 H.265 at CRF 34 using ffmpeg.
Its SHA256 hash is a122f42be8885cf7142afd25cfaf018a658cee81839c9564ad8d4049c9e15307.
(For the record, the spliced Matroska (MKV) recording is 0.576 GiB; this video (with -preset veryslow) is 9.2 MiB (6.98% larger than the CRF 36 I used in a previous version; but that's fine I suppose).)
Slideshow written with Vim and Vi. Unicode box-drawing chars look ok thanks to tmux's screen $TERM.
LC_CTYPE is en_US.UTF-8 for the slideshow in Vi and C for JUnit launcher.
Java used here is OpenJDK 21 or something idk.
This video took a while to make.
