From a G+ post by Craig Nansen that I found within the Google Certified Discussion community in G+ (which anyone can join) something brand new called VideoNot.es which, in Google Drive, splits your screen and puts the video on the left and the notes on the right. As you take notes, it records where you are in the video. You can then save the video and the notes in Google Drive. If you just want the notes, drag your cursor over them and paste it into a regular Google Drive document. Above is a short video on how to do this.
