Suppose you’ve to share only a part of a YouTube’s video and not the entire video.
Everyone knows how to share the beginning: you just have to check the “Start at" checkbox under the Share tab. But how do you set the end of it?
Then you’ve to set the start and the end. On YouTube you can find the time expressed as “xxhyymzzs" but for this purpose you’ve to convert everything in seconds. An useful help is provided by this free online service: convert hours, minutes and seconds to seconds.
After having converted both start and end to seconds, the final link is: http://www.youtube.com/v/N79DhXBBLNo?version=3&start=xxxx&end=yyyy&autoplay=1&hl=en_US&rel=0
Pretty easy, isn’t it?
