VideoNot.es gives you an opportunity to take notes while your are viewing a video. It's in Beta version so you can expect updates as you use it. I love how you can take notes right beside the video and the notes are stamped with the time frame of the video. So, you can go back and edit your notes and review them with the video.
This is great for me as I struggle sometimes to learn how to use an application. And, it's wonderful for your students when they are viewing a video in your classroom and required to take notes. The notes are automatically saved on Google Drive.
