It depends on what you’re trying to achieve. In my opinion, there are two aspects to magic-intimacy and presentation. I agree with most of what Christopher T said, magic is first about intimacy with the spectator-generating that closeness and amity so that instead of just doing cool stuff with your hands/trying to fool them, you’re giving them an experience. There are fantastic essays in the Art of Astonishment series on this concept.
However, magic is also an art form. Here’s where videos can be good. For example, the aesthetics of card manipulation or cardistry can be amplified through good editing and music, though too much always ruins a video. Performance videos are also good for reaching out to a larger audience, though you’re trading a larger audience for lost intimacy. It’s why if you show someone a video of a trick you did, they’ll never be as amazed than if you just did it for them, EVEN if you messed up live and did it perfectly in the video.
One thing to never do on YouTube though-make tutoriels on magic that is a) not yours or b) not public domain, and even that’s taboo. It’s not up to you to release those secrets to laymen and it could come to bite you in the ass later on.
As a final note, Jibreezus is the exact opposite of what you want to be if you go into YouTube.
