Shameless plug for anyone that wants to go deeper on specific video topics: I've been organizing a conference for video devs for 11 years now and there's a wealth of info in the recordings. A talk from the most recent one on hacking a Sega Genesis to stream video might not seem that practical, but there were some fascinating bits on compression (or, rather, not being able to use actual compression). https://www.youtube.com/watch?v=GZdxdpw-3nI

If folks want to get involved, there's also a chat community that's pretty active: https://video-dev.org.
