Once you have asked for permission to download a clip from YouTube by sending the up loader of the You Tube clip an email, you can use Clip Converter for free, online to download a video clip. I currently like Clip Converter as it does not require any software to be downloaded. To use Clip Converter, simply paste the URL of the You Tube clip that you would like to download, select the file format and then download. If you are intending to download the clip for use on an iPad select .mp4 format.
