** background notes: man ffmpeg-codecs says -g is group of picture size, but
online sources call it the "keyframe interval." In vp9, at roughly > 2 seconds
worth of frames, it starts to increase latency at a corresponding rate. If cpu
struggles, adjust cpu-used upward, max is 8 which uses the lowest cpu.
* Audio Bitrate: `96 Kbps`
* Audio Track: check mark on 1.
