There's no question, in my mind at least, that if you want to pursue a solid foundation in magic your going to have to rely upon print resources. There is a historical progression in magic literature that one must experience in order to truly appreciate our art. Personally, I especially love books like Stars of Magic, Greater Magic, Modern Coin Magic, and Expert Card Technique because in their hard expository style they tend to lack an author's voice, leaving the imaginative aspects of the study to me. Later books penned by authors like Lorayne, Kaufman, Minch, Burger and Racherbaumer often offer the kind of deep insight one needs in order to develop as a thinker and hopefully as an artist. I've been a teacher for almost twenty years and almost reject the notion that there are people who simply can't learn from print text. People with a learning style that heavily leans towards one mode of learning are rare. All that said I think that videos, particularly some produced over the last few years, are really helpful and enjoyable. Certainly, nothing beats watching a live performance in order to understand how an artist works, interacts with spectators, uses timing, builds impact, etc. Ultimately it comes down to what you want to get out of magic. If you like to watch a video, learn a trick, show it to a few friends or strangers, great! If you want to consider yourself a student of magic and are deeply interested in all that magic entails, print resources will have to be a significant part of your education.
In your original post you mentioned that as a beginner you find it harder to learn from books than videos. That makes a lot of sense as... you are a beginner. Many magic books, say the Royal Road to Card Magic, must be cracked, so to speak. You look through a book until you find something you can learn, practice, and eventually do well. You then go back and try it again. Eventually, it all starts to make sense. With a book, you have to figure out and learn, with a video you are basically mimicking; thus, the sense of discovery and learning is lost. Magic literature has an inherent language and sensibility that must be acquired, in time you adapt and doors slowly open. There's a learning curve there for sure, but the rewards are far richer in the long run.
