You will notice that you have all the usual features of YouTube videos, such as closed captioning and expand to full screen, but also the video can be slowed and a button allows an easy repeat of individual scenes. The nice thing is that because you are embedding rather than downloading, you don't have to own the video to annotate it. You can also get the video to start at a specific place, rather than the beginning, thus eliminating sometimes annoying introductions.

I'd strongly recommend this tool if you are using authentic video, documentaries, etc. If you upload your own videos to YouTube, Embed Plus would make them more valuable to your learners. You could, for example, add directions for note-taking, as I have in the sample above. Or place a strategic assignment. Pro features, for as little as $14.99/lifetime, may be worth the cost, since you could then link to other websites.
I don't see how this tool can continue without charging anything, unless Google buys it.
