It used to be, when you wanted to share a video, you’d attach it to an email and send it out to your friends.
Now when you want to share a video, you find the video on youtube and send a link — that keeps everybody’s inbox from filling up.
Change the Starting Position
Sometimes, you’ll want to make sure your friends see exactly what you’re talking about. To start the video at a specific spot, you can append “#t=MMmSSs” to the end of the url (link). You’ll replace the uppercase Ms with the number of minutes and the uppercase Ss with the number of seconds in the video where you want playback to begin.
For example, if I want to jump to the 2 minute, 39 second point in a video, then I would add “#t2m39s” to the end of the URL (example: http://www.youtube.com/watch?v=L_HkH8huuzA#t=2m39s)
This trick also works for embedding a video. Although, when embedding use “&start” instead of “#t” and it’s in seconds only. (example http://www.youtube.com/watch?v=L_HkH8huuzA&start=159). Try playing the following video, it will start near the end.
Many YouTube videos are now available in HD. To ensure you link to the HD version, append “&fmt=22″ to the end of the url. (http://www.youtube.com/watch?v=L_HkH8huuzA&fmt=22)
Maybe you want to transfer a video to your iPod or laptop for offline playback. If you load a video in youtube, you can swap out “youtube” for “keephd” in the URL. If there is a forward slash “/” after “watch” then you may want to remove that as well. This new url will take you to keephd.com and it will give you links to download the youtube video.
