It only recorded audio!

I really wanted to record a clip of a video off of YouTube for a Tumblr edit I was making and the reviews said this was the best one. It worked very quickly and saved the video instantly,but when I went to watch it,it only recorded the sound. No visuals at all. The audio sounds great though.
