Is it possible to remove the pop-up Youtube ads from embedded videos?

I've removed things that popped on my screen, but haven't had success with Youtube ads. These really distract my struggling students. Well, they annoy everyone, of course, but these kids have attention deficits.

I'm still not comfortable with video in Captivate. I have much to learn...and so little time, like everybody else!

Thanks to anyone who replies.
