The idea is to ‘share & play’ only that part of video in which the real content of interest is. In simple words, the clip from the video that I want my friends or other viewers to see!
Example: http://www.youtube.com/watch?v=S473XaWNHmk&START=6-42&END=7-12
Because, seriously, when we share videos, we do sometimes comment with it saying: “Hey, check at 1:20, see what the dude is doing!”. So, the point is simple and apart from that the other guy will view/download only the clip that is of interest not the whole lengthy video!
Below is a video (from) and I just want to share almost 30 seconds of the clip from it, starting from 6:42 till 7:12.
Clip starts at 06:42
Ending at 07:12 (the below pic looks abit same as above but its not; the building below is under attack in the game 
)
After selecting the clip from the video, what I want to share is of exactly 30 seconds as below:
Clear enough.
