The Subdi lectures on YouTube are old and don't have much information, but they were really helpful. It's good to go back and look at the parts I missed, and the explanations are very detailed, so it's very helpful. However, for those who have no concept of nodes and node names, it would be more effective to personally search for the relevant parts and then listen to this lecture. However, once you get used to Subdi, you'll be able to follow along... Thank you for the great lecture!
