When linking to YouTube, it is well known how to link to a certain time segment.
This is how it works: http://youtu.be/zSv5CvhOEsA?t=3m46s
In fact, YouTube has a user interface similar to this, which makes it easy to create links.

However, if you try to do this with the "embedded code", no such user interface will appear. As a result, it gives the impression that you can only link to the beginning of the video.
In fact, putting a string like "?t=5m8s" in a "src=" link won't work.
However, it is actually possible to link to part of a video by using other syntax.
In the above example,
<iframe width=”420″ height=”315″
src=”//www.youtube.com/embed/zSv5CvhOEsA? start = 77"
frameborder=”0″ allowfullscreen>
You can add a start point by adding "?start=" followed by the number of seconds you want to start from, as in
Similarly, you can specify the end location by adding a parameter like "end=108". It looks like this:
<iframe width=”420″ height=”315″
src=”//www.youtube.com/embed/zSv5CvhOEsA?start=77&end=108"
frameborder=”0″ allowfullscreen>
If you actually try it, this is what happens.
It worked!
Well then!
