YouTube in 720p!

YouTube has been messing around with 720p video quality. All you need to do is add a parameter to the video URL and it will try to show it in 720p quality. Doesn't work on the forum for some reason, but I've included a "proof of concept" as attachment.

Only works with shorter (tried with 10mins and 3mins, only worked on latter) movies that are uploaded in 720p format.

Finally we can put "HD" movies to YouTube without loss of quality.

JettPilot: Just upload in HD resolution. Not sure how YouTube decides to make it a HD video. Watching and embedding is only possible using the method I showed in the HTML file. Once you are inside that player, though, you will only see the movies in this quality (if they are available, that is).

I've been playing a little with the embed feature. Here's what I came up with. This should make it easy to check if your videos are 720p:

Take any YouTube video URL, for a video that's been uploaded in HD,
and simply put
&fmt=22
at the end of it. Play it full screen and if it's encoded in HD, it'll play in HD.

(BTW, it used to &fmt=18 during early betas, and you'll find many references
to that, but it's been changed to &fmt=22)

If anyone's got a HD clip with good detail and relatively high motion
I'd love to see what it looks like on *both* YouTube HD, and Vimeo HD.

The biggest problem I see with YouTube lately is that it's just been really
slow to download lately, even for normal "high quality" SD videos it's slow,
so HD clips take forever. I've got bandwidth coming out my ears
so I know the problem is at the YouTube end.

Same source file. Don't forget to add "&fmt=22" in the youtube vid.

Thank you!

That was exactly what I was looking for.

My subjective opinion is that YouTube favors motion over detail by
a noticeable margin. For example, load up both vids in different windows, and
queue em up at the clip that starts at 00:45 and goes to 1:13.
YouTube has smoother motion on the dive. Look at the reflections
on the snow, and the footprints in the road on the right for detail. They
both are very clear.
But watch the same in Vimeo HD and the motion is a bit choppier,
like it's dropping frames but when the sun reflections and footprints
pop, they *really* pop.

The end result though, is that I think the YouTube HD version looks
overall better as I prefer the smoother motion. But Vimeo has
the download link.. sooo..

Ian, Vimeo reduces the framerate to 15fps, I think this is why their video is so choppy. Since the YouTube features are not "official" yet, it will remain to be seen how they handle it. 30 fps at 720p could quickly eat up their storage

We live in a flash video world, thats just the reality. The only hope is that flash video improves over time.....

From my understanding youtube has been farting around with the idea of HD for some time but they were too late to the party. First they implemented the "High Quality" feature which I think was a test bed to check server load. Now were in the HD arena and clearly they are desperate in trying to compete with vimeo and some of the other sites that have already implemented HD for some time.

As JetPilot said flash is the death of them and until they move away from that format it will be difficult for them to show the same clarity as some of the other sites. They do however have numbers in their favor so we will see what happens. Its always interesting to watch how these things develop.

If I had to guess they eventually drop FLASH altogether, in a broadband world the compression is no longer as necessary.

I disagree. I don't like the flash player at all, but bandwidth is still an issue
for a lot of people, and it'll continue to be an issue for YouTube
(and anyone else, if they ever had anywhere near the volume of YouTube).
Even just moving to their "high quality" versions, I've found that
YouTube has become extremly bogged down lately. They're going to need
significant infrastructure upgrades if they want to support HD at
large scales. My guess is, they'll do what Vimeo just did, and
start charging people for HD service. (Vimeo still allows 1 free HD upload
a week, but no embedding. If you want full HD support you
have to get Vimeo Plus, and even then they'll charge you more
money for any embedded content that gets over 1000 hits).

We'll need to get used to flash at least for another 5 years. The next technology in line is Silverlight ... I'm not sure which is the lesser of the 2 evils.

Compression and video quality is of no concern in flash format, since it's just a container which can include various kinds of compression algorithms. There is, however, always a tradeoff involved. Storage space, CPU cycles for conversion and bandwidth cost on the provider-side (YouTube,Vimeo, etc). Bandwidth and PC speed on the client side.

If YouTube were to switch to HD, either paid accounts or dramatic increase in ads will not be avoidable. I pray for the first.

Your right I was wrong. After doing some research I was under the wrong impression that broadband was more widely accesible then it really was. Lost of places around the country still limited to dial up. Interesting to see what happens non of the less.
