If you frequent YouTube, at some point you’ll probably go to watch your favorite video only to find that it’s been removed. Videos can be removed for a variety of reasons, like YouTube removing them because of a copyright issue, or even owners removing their clips.
By using Delutube, you still have a chance of getting those deleted clips back. Think of it as a Google Cache for your Videos. Google Cache can pull up a webpage that’s no longer available, and then you can go view it as a cached version. Delutube will work if the video hasn’t been permanently deleted from the servers.
All you have to do is find the video ID that’s found at the end of the URL, go to Delutube and enter in that ID, and if it hasn’t been permanently deleted, you’ve hit a jackpot!
Another service out there called Kiss YouTube provides an easy way to download all of your favorite videos. All you have to do is enter in the word “kiss” right before YouTube in the URL so it would look something like http://www.kissyoutube.com/watch?v=nsjuPX8C2lo.
After pressing enter, you’ll be taken to the Kiss YouTube page where you’ll have the option to “download now” in flv format, or send to your friends. They also provide a download link for the video in case you want to post to a forum, blog, IM, etc.
Because they’re using the same logo as YouTube, they might run into some issues. But for now, it’s one of the simplest ways I know of for downloading your favorites. Just type “kiss.”
