You may have noticed over the last few months a number of videos have been popping up on YouTube offering a high-quality alternative. Unfortunately, high-quality doesn't mean HD. That is, until now.
An engineer at YouTube has let slip that by adding just a little bit of code to the end of a video's URL can up the quality of the video to 720p.
While it doesn't work on all videos – it all depends on how good the source material is – it does make a huge difference in the crispness of the footage.
The code in question is &fmt=22. Add this to the end of the URL in your search bar and it will apparently stream the video in HD quality.
One of the examples given is an update to the YouTube hit 'Where The Hell Is Matt?'.
So far, YouTube's high-quality button only offers mp4 videos encoded using H.264 with stereo AAC sound at 480x360, so a 720p upgrade is welcomed.
