There are millions of videos on YouTube and between all the kitten and auto-tune videos there is a lot of good educational content.  A good place to start would be YouTube’s education section, http://youtube.com/edu.  If you are a regular user of YouTube you may have come across times where you only wanted to use a segment of a video.  Maybe you have wanted to mix together a handful of videos that are related to the same topic.  Was there ever a time where you just wanted to extract the audio?  The following applications will allow you to do just that.

Have you ever shown a segment of a long YouTube video to you students and felt like you were using too much class time searching for the starting point of the video?  Was this a distraction to your students?  Now you can “chop” these videos into smaller segments using TubeChop.  TubeChop allows you to easily chop the beginning and or end of any YouTube video and share it online.  All you need is the URL to the YouTube video.

ListenToYouTube.com allows you to extract audio from any YouTube video (non-copyrighted content only) and turn it into an .mp3 file.  This service is fast, free, and requires no signup. All you need is the YouTube URL, and the software will transfer the video to our server, extract the MP3, and give you a link to download the audio file.

Spending too much time in class searching for YouTube videos that are about the same subject?  Dragontape is a collaborative webservice that lets you create up to 3-hour mixtapes of your favorite YouTube videos.  You can embed the mixtapes right into your blog, wiki or anything else that allows for embed code.  The embedded player offers the same gapless playback and the same tape controls as the webapp.

This is also a tool that could be used for student projects.  Dragontape has the ability to invite users to collaborate and create mixtapes.  Student could group together and create a mixtape on a certain class topic.
