You might know that you can quickly copy youtube video embed code by right clicking on a youtube video while its playing. There is a new option which lets you copy the link to that exact moment in the video, so that when you share the link url, clicking on it starts the youtube video from that specified time you copied the link.
Simply Right-Click on a youtube video while its playing and click on "
Copy video URL at current time".
For example the one I copied from the video above, I got the url http://www.youtube.com/watch?v=geyAFbSDPVk#t=56s
Notice that #t=56s is what controls the start time of the video. You can just reduce it by few seconds before sharing to make sure people don’t miss the first few words.
The basic idea to add is #t=XmYs where X are the minutes and Y are seconds to the end of the video URL. This also works for youtube embed codes.
For example, you can manually specify minutes and seconds by changing the parameters as #t=01m28s (for 1 minute and 28 seconds).
This might be very useful for sharing videos starting from the important part of a speech or a funny part in the video etc.
There are other online services which lets you add advanced playback controls on youtube videos by letting you customize youtube player for slow, zoom, annotations etc.
You can also try out YouTube Subtitler, an online service which lets you view lyrics on music videos or transcripts, subtitles on popular speeches during playback.
