Question: how to download a youtube video from a website?
Answer: Copy the URL of the video you want to download, head to KeepVid.com, and paste it in the bar at the top. Then click "Download" to the right of that bar. Do not click the large green "Download" button. It will load for a few seconds, then you'll have the option to download the video in FLV (Flash), MP4, or WebM format.
