Here are a couple of things that make me want to watch a video:
First, buy a nice camera. Webcams give a vibe that the content is going to be sloppy, ill-performed, and boring. Next, keep your videos as short as they can be without sacrificing quality. If a video is 30 seconds long, I'm twice as likely to watch it again than I would a 5 minute video. Plus, you want to leave people wanting more, not less. Last, whether it's magic, flourishing, or anything, make sure to polish your content. Remember, you're competing with billions of other videos on YouTube and you have to give it your all to be noticed.
