If you want to embed a video but do not want users to waste their time looking at the irrelevant parts, you can skip that! Here’s how to do it.
When you receive the embed code from YouTube, add &start=30 to the URL part of the code. In this example, 30 means 30 seconds but you can change it to any desired value. This change in the embed code is reflected in bold in the example below:
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/R3XqTDgX4Us&hl=en&fs=1&rel=0&start=50"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/R3XqTDgX4Us&hl=en&fs=1&rel=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>
Due to adding a start string with a value of 50 seconds, the following video will now start from the 50th second and will go till the end.
