Whenever you want to embed YouTube videos in your blog posts, you can specify the start and end time, thereby making it easy for viewers to focus on a particular scene that begins from ‘xx: xx’ seconds and ends in ‘yy: yy’ seconds.
All you have to do, is to add ?start=xx&end=yy&version=3 at the end of the Youtube video src (URL)
E.g
If original embed code is this :
<iframe width="640" height="360" src="https://www.youtube.com/embed/kzjRiSPRdLM" frameborder="0" allowfullscreen></iframe>
and I want it to start playing from 1min45secs and end in 2mins 01secs, I will use the embed code below:
<iframe width="640" height="360" src="https://www.youtube.com/embed/kzjRiSPRdLM?start=105&end=121&version=3" frameborder="0" allowfullscreen></iframe>
Demo below:
NB : The start and end time must be specified in seconds.
Hence,
1min 45secs = 105secs
2mins 01secs = 121secs.
