Keepvid is a keeper

I think a lot of us have tried saving an embedded video from sites like YouTube, IFilm and Google Video - but never found a sure way to do it.
Thank God there's Keepvid which makes downloading of these online videos a breeze.

All you have to do is put in the url of the page where the clip you want to keep is located and hit 'Download'. And if you're not sure where to start - just have a look at the 'Top 20' videos. There are many other sites that are supported by Keepvid but it's too mmuch to list them all here.

And if Keepvid ever goes offline there's always this site to fall back to.
