No, not really. If somebody wants your content badly enough, they will figure out a way to get it.
There are a lot of solutions out there if you Google for it, but almost all of them can be easily overcome by someone determined enough. It’s just like if you run a small shop, there’s no way to prevent all shoplifting. It’s going to happen, no matter how many security cameras you have in place. People are clever.
The best solution is to make sure you (or your logo, or both) are in the video. Kind of hard for someone to claim they didn’t steal your video when you’re in it.
I’ve worked with a few people in the past who have had this concern. Their websites went away after a while, because they spend so much time locking stuff down that it was almost impossible for their customers to get to stuff, and they spent more time worrying about security than about content and marketing.
Just make great stuff, and promote it well. If there is a demand for your product, you’ll more than make up for whatever gets taken.
