YouTube Plays With Higher Resolution Clips

The average YouTube user isn't likely to stumble across them, but an ongoing test appears to be spreading higher-quality versions of some videos throughout the site.  All that's needed to access the clearer clips is the addition of six extra characters at the end of a URL.

When calling up a video, paste "&fmt=6" or "&fmt=18" into place, and, if you're lucky, the video will reappear and look significantly better than before.  Affected clips aren't exactly widespread, so a little luck or perseverance may be required to find them in the wild, but it seems worth a try to us.
