To specify a point, append a tag to the end of your video link with the following syntax: “#t=1m45s” (you can change the numbers before the ‘m’ and ’s’ to edit the minutes and seconds, respectively. Here’s an example: http://www.youtube.com/watch?v=1bibCui3lFM#t=1m45s As another nice touch, YouTube will also automatically detect when someone mentions a time in a video comment and add a hyperlink to that point in the video. The feature just went live and there isn’t any easy way to do this though the YouTube UI without manually adding the tag.
