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.
Flash 9 supports h264 video codec.
XML is like violence. If it doesn't solve the problem, use more.
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.
iPhone loads the higher quality .MP4 video because it can't play .flv - Apple TV probably does the same thing for the same reason.
Username taken, please choose another one.
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.
I couldn't see any difference in quality between the regular version and the "fmt=6" version of the skating dog.
I suspect this is already taken care of.
I use noscript, and instead of giving youtube permanent permissions, I always give it temporary permissions. Well, in recent weeks, I've needed to grant permissions to both youtube.com and ytimg.com to get videos to play, so they seem to be farming out their bandwidth to a caching service.
I certainly wish I had known about this before I spent a decent amount of time re-encoding motion jpegs to get them under 100MB.
You must not be aware of it, but just about every video on YouTube is copyrighted.
Looks like I found the answer:

They probably use only the basic "blend" form of deinterlacing, rather than checking whether it is best to use IVTC for "Film" (typical DVD) or one of the fancier deinterlacing methods like TomsMoComp for "NTSC" video (typical camcorder).
It's probably best to deinterlace video yourself prior to uploading to YouTube, if you care about quality.
It's a noticeable difference to me. Specifically, edges are substantially less noisy in the high quality version, whereas in the low quality version there are some pretty obvious compression artifacts around edges.

These are the only ones I found (the skate dog shows up too) in a google search for site:youtube.com "fmt=6"

My guess at this point is they are reencoding the original uploads iff they are higher bitrate than the old codec youtube was using.

Nothing laughs forever.
Thanks. Someone else linked to their own video of a DOOM hack demo here. The quality is pretty bad but is horrendous without the parameter. I've also found a video of Grace Potter and the Nocturnals here.

Install this Greasemonkey script. You don't need Javascript at all to watch Youtube clips.
d'oh
The exploit used to upload these videos (changing the file header so the bitrate seemed to be less than 348kbps) was closed by YouTube a while ago. For normal accounts, YT re-encodes all uploaded video, even .flv below their target bitrate. I did a bunch of testing recently and blip.tv was the only major site that would not compress uploaded flash. The best bit for YT is to upload a large and high-quality original and make use of the &fmt=18 parameter to access the H.264 version. The audio and video improvements can be dramatic.
I can! http://uk.youtube.com/view_play_list?p=4806B1FAAC9C7DE1
You know, Microsoft's street address also says a lot about their mentality.
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

Dailymotion announced HD support some weeks ago, so I guess Youtube wants to have that too.
