Higher-Resolution YouTube Videos Currently In Testing
jason writes "YouTube has never really been known for streaming videos at a high resolution, but it appears that they are taking early steps at providing higher quality videos. The project was announced last year by the site's co-founder Steve Chen, and now appears to be in the earliest stages of deployment. By adding a parameter onto the end of a video's URL you're able to watch it in a higher quality (in terms of audio and video) that is actually quite noticeable. Not all videos have been converted at this point, but they do have millions upon millions of videos that they need to do."
iPhone users have been enjoying H.264-encoded YouTube for many months already.
To be frank, I've not been on YouTube.com ever since I've gotten the iPhone. The video quality is SO much better on H.264 than crap^H^H^H^H flash players that it's worth wasting time with it. Plus, you can actually pause, fast-forward, rewind and skip to any point without it failing like flash players always do.
According to some reports, yes, they have kept the originals.
The government can't save you.
I hope H.264 will be available in flash soon. Stage6 had to close because of the expenses in delivering HQ videos, which is bad news.
I'm not insane! My mother had me tested.
What do you think they are converting you lamebrain? They kept the originals, so no upsampling needed (doesn't really work anyway), they just RE-encode the original.
MMO Quests are like orgasms:
You may solo them, I prefer them in a group.
It was widely reported (and by that I mean, Steve Jobs stood up on stage and announced it) that Google were storing all new videos as H.264 (and steadily converting old ones) for both the iPhone/iPod touch and Apple TV.
I would imagine this initiative is related to that.
It already is.
Some guy in the comments on the blog downloaded both formats and they came out in exactly the same size. People here are also commenting that they only changed to support H.264. This means that they do not have higher bandwidth needs, but higher processing needs due to a smarter codec (H.264).
Personally I've played around with x264 and the improvements in quality are pretty impressive with enough encoding time and the right encoding parameters thrown at the encoding process.
&fmt=18 gives you the h264 iphone video, also playable in the latest Flash 9.0 r115.
&fmt=6 gives you the comparable quality but higher bitrate Flash video which works on older Flash players.
And &fmt=17 gives you a crappy low bitrate very low resolution mpeg4 video for older/cheaper phones, but it isn't playable in Flash.
... actually there is high quality content Youtube -- the copyrighted stuff.
Looks like I found the answer:

Perfume - Polyrhythm (Japanese music video): http://youtube.com/watch?v=qjL_FM23FzU&fmt=6
Touhou 8 - Final Boss (Japanese video game): http://youtube.com/watch?v=UOWR1_uMdW8&fmt=6
CNN/Univision Debate: http://youtube.com/watch?v=_BGyWYtee18&fmt=6
These are the only ones I found (the skate dog shows up too) in a google search for site:youtube.com "fmt=6"
http://www.google.com/search?q=+site:youtube.com+%22fmt%3D6%22&num=100&hl=en&safe=off&filter=0
My guess at this point is they are reencoding the original uploads iff they are higher bitrate than the old codec youtube was using.

Cheers! Verified.. I downloaded the video files for each format from youtube.. they are as follows:

Presumably anything that's available on the iphone will be available in fmt 18 and/or fmt 17. 18 looks good
