You might have noticed that the OP hasn't reared their head since the first post. Perhaps the reason for this is that people keep telling the OP that they "must do the maths" or words to that effect. If you go back and read the OP's (only) post the OP complains that many videos omit or gloss over the maths and goes on to comment on the futility of this at length. The OP doesn't need repeatedly telling that maths is important, they have already told us that they think it is.
This kind of diversion often seems to ever crop up when someone asks about learning resources here. If the OP had asked "Where can I get some nice red patent leather dancing shoes?" it would be (I hope) obvious to any commenter that they were well off answering the question if they started extolling the virtues of green rubber waders.
If anybody can answer the OP's question then please do so (I can't, I'm not a great consumer of video tutorials) but if you can't answer it, please don't offer your version of the answer to "How do I get a good education in X?" in lieu of an answer to the actual question posed. Please don't say "read books" when the question is "do you know of any good video series".
Perhaps the OP just absorbs information better from videos, perhaps they are dyslexic and don't like shouting it from the mountain top; whatever it is, I am sure they had their reasons for asking specifically about videos. People's styles of learning differ, offering the way that suits you as a panacea is not particularly helpful. I can learn just about anything from a book, my other half strongly prefers to go and take a taught class and struggles if a book is the only resource.
Nothing else short of direct insult is going to put a beginner off asking questions here faster than having what they have written ignored and then having a different question answered instead of the one they actually asked. Please people, read beginner's questions carefully and answer the actual question asked; ask for clarification if necessary, but please don't sideline onto a different topic.
I'm not trying to dissuade helpful comments, just ones that frustrate the original question.
The thing I find a bit ironic is that a couple of the people I regard as 'guilty' in this thread are often amongst the most helpful and knowledgable when they are answering the right question (including some of mine).
