This is interesting stuff.

So apparently, if you’re on Youtube, and you add the ‘&fmt=18‘ to the end of the URL, you can watch the vid in HD. Actually, I don’t think it’s so much as ‘HD’ but ‘Higher Definition’ than the usual Youtube standard.
Pretty cool.
It doesn’t seem to work for embedded vids though. Has to be used when watching directly on the site.
Also one more thing I found out was that this also depends on the original source video. For example, if the source of the video was, say, from a low quality source like a mobile phone video function, the code doesn’t improve the quality of the original video. It’s limited by the quality of the original video. Basically, garbage in, garbage out.
However, if you’ve got a better source, say, from a digital camera or better yet, from a video camera, the code helps to bring the video back to part of the original source so you get a ’sort-of hi-def’ experience. So it’s not really Hi-Def, more like High-er-Def. Hehe.
