I feel like the video should have some summary, because I didn't want to watch it (just read) just to know what the credits were for. Also, the voice in the video is strange. It feels like it is cut as well as volume changed. I feel it is some form of text-to-speech going on but it doesn't really sound like it usually does. What's going on?
