It’s easy to create a link to a YouTube video that starts the video at a specific time.  Useful if you are linking to a video that has a bunch of filler at the beginning.

If you’re linking to YouTube:

Add an anchor tag to the end of the URL that specifies the number of minutes and seconds to skip.  The example below starts the video 1 minute and 50 seconds in.

http://www.youtube.com/watch?v=buNcHofCrAZyCrAP#t=01m50s

If you’re embedding the video

Add a url parameter to the querystring in the code.  You have to do this in 2 places.  Oh, and this time you have to indicate the number of seconds to skip, so our 1 m, 50s becomes 110.

<param name=”movie” value=”http://www.youtube-nocookie.com/v/buNcHofCrAZyCrAP&hl=en&fs=1&rel=0&start=110“>

<embed src=”http://www.youtube-nocookie.com/v/buNcHofCrAZyCrAP&hl=en&fs=1&rel=0&start=110”

Easy stuff that will save your viewers precious seconds.  Like when they watch this.
