This year, I have loved using Zaption. I read yesterday that Zaption is increasing some of the free options. Now you can include multiple videos per tour, and it does not limit the number of viewers per video. It is great for having students watch videos. I updated the videos in my group if you would like to see them. You can check them out here. I have 15 videos that I have used this year with my Spanish II and III classes. The analytics are really strong as well! Check it out when you have a chance!
