Enter a youtube URL, get the video code for it. Simple as that!
If you go to a YouTube video you often end up with a complicated URL full of obscure references. For example, try copying this YouTube URL into the box below, and you will get the short code for the video.
Avron Marcus used this to create a YouTube URL Generator for linking to a specific part of a video, which he described in his blog entry on it: http://avronm.tumblr.com/post/28476057026/deeplinking-to-a-portion-of-a-youtube-video
The direct link is: http://uncharted.livesheets.com/forms/ca0e66a90629fe6324b433f24492fce9ae4e084b
and the embed code is:
<iframe frameborder="0" height="320" marginheight="0" marginwidth="0" scrolling="no" src="http://uncharted.livesheets.com/forms/ca0e66a90629fe6324b433f24492fce9ae4e084b" width="480"></iframe>
