How to skip the introduction of a Youtube video?

To view directly a part of a video that you feel relevant to your visitors, or to skip an introduction that is too long and intrusive, a parameter must complete the code to embed provided by Youtube.

&start=a number of secondes 

The number of seconds is displayed on the video panel.

This option must be added to both URLs, so that the complete reader has this form:

<object width="425" height="344">
<param name="movie" 
       value="http://www.youtube.com/v/G4evlxq34og&hl=fr&fs=1&start=190">
</param>
<param name="allowFullScreen" value="true"></param>
<embed src="http://www.youtube.com/v/G4evlxq34og&hl=fr&fs=1&start=190" 
    type="application/x-shockwave-flash" 
    allowfullscreen="true" width="425" height="344">
</embed>
</object> 

Demonstration:

This demonstration gives explanation about a commercial exoskeleton that multiplies your force by 5 or allows disabled people to walk.

Consider the case where you do not want to embed the video in a page but put a link on the video instead, you have to options.

Use a parameter recognized by Youtube:

#t=3m20s
http://www.youtube.com/watch?v=G4evlxq34og#t=3m20s

The parameter is a number of minutes followed by the m letter and a number of seconds followed by the s letter.

Update June 2011

Now is possible to display a menu with the right mouse button and to save the URL of the video with a starting time.
This tutorial is now deprecated for an URL, but it remains useful to know how to modify the starting time when the readed is embedded in the page.
