Sound:
mp4a: MPEG-4 AAC LC
44100Hz 118 kb/s tot , stereo (2/0) (yep, there it is !!!)

And really: Looks great !


Hello,
where did you get aac stereo audio? Can you give us a link?

How much does it take to convert to h264 with &fmt=18 and do you think that this new format can be embedded?

The answers are already mentioned in this thread. Realize Google/YouTube are just TESTING at the moment.
When you analyze one of the format 18 mp4 files, this is what is says (example):
Code:

So as you can see, it contains 2 channels. Yet the audio is actually (still) mono. They either merge source audio to 1 channel, then encode in 2, or the source was already mono, and they always encode the fmt 18 in 2 channels.

As far as the embedding goes;
It works, but video sometimes gets only played in part, and/or the embedded player behaves strange laugh.gif Here's how to use it embedded: add "&ap=%2526fmt%3D18" after the two occurances of "&rel=1" (or directly after the video-code-urls) in the embed code. An example embed code that gives you the fmt 18 version:
Quote:
<object width="480" height="394"><param name="movie" value="http://www.youtube.com/v/-DGjfcUkRGk&ap=%2526fmt%3D18"></param><param name="wmode" value="window"></param><embed src="http://www.youtube.com/v/-DGjfcUkRGk&ap=%2526fmt%3D18" type="application/x-shockwave-flash" wmode="window" width="480" height="394"></embed></object>

Note that Flash 9 r115 better be installed at the viewer's side.

Here's an easy way to use the embed code to play back fmt=18 video: http://paste2.org/p/43210

Thank you it works biggrin.gif

Anyway it's really strange this audio thing that they do converting to mono and then stereo.

I've tried to upload a file called video.mp4 with aac 96kbit stereo and h264 480kbit 480x360, maybe they don't touch the file as they don't with flv...maybe. I've just to wait ...

Ive been toying around w/ the settings and the fmt=18 has made a big difference on 2 videos I have posted. However, when I try to embed the video on my blog (manually adding fmt=1cool.gif it always seems to go back to the old format.

Anyone had any luck embedding YT videos w/ the fmt=18 (or other HQ) format?

I've never tried embedding with fmt=18 but fmt=6 seems to work near perfect on every video so far, the video plays in HQ from start to finish with no problems. The only small issue is that you can't use the video slider to skip or rewind to certain parts, doing so will cause the player to go back to the beginning of the video. The best thing about it though is that anyone can watch it without having the r115 flash update.

In the limited testing I've done it looks like appending '&ap=%2526fmt%3D18
' to the URLs works.

See the embed code here:

What do you think could be the minimum system requirements to play 480x360 h264 on the web?

Changing wmode from "transparent" to "window" greatly lowers the cpu usage in most cases.

You're right! Changing to window decreases the cpu of 25%. Thanks wink.gif

Thanks, great tip!

Also, if you embed the format 18 version, you might as well change resolution to 480x360, meaning width="480" height="394" in the embed code. I've highlighted all changes in the example above. wink.gif

i guess yt can now turn a decent profit...and i can no longer have teh freakin FUN

i still get this message when trying to watch the vid "This video is no longer available due to a copyright claim by a third party." if they have any brains they wont make it count as a strike against my channel.

i know it's weird but they were set to release it last year sept..but they finally made it public now. according to them it can recognize video AND audio.and they say it is "very accurate" HAHAAA and my only purpose on youtube is to bring people the latest stuff from movies that the studios usually don't want public

I bet the video recognition is something laughably simple yet effective, like reducing the video to short list of values, like normalized average brightness per second, and comparing it to every signature, one at a time, also trying to account for time offsets caused by intros and such.

I understand you guys want to be the One to discover the new and latest way to force Youtube to pump out the HD out of video.. Don't get me wrong,I been trying too.
Though , through my endeavors I found that maybe you guys should all switch to Mozilla Firefox then download the Greasemonkey plugin firefox plugin: https://addons.mozilla.org/en-US/firefox/addon/748 then INSTALL IT >>>then go to http://userscripts.org/scripts/show/23535 ... and install the script >> make sure greasemonkey plugin is enabled. You should have a SWITCH TO HQ VIDEO STREAM BUTTON Under your YT PLayer .

well I went to the site through a proxy or google cache because If I used the direct url it only redirects me to the myspace main page, as I dont have quicktime it only showed the flash video version of the trailer, then I searched for the video in the firefox cache and uploaded to my YT account and it wasnt rejected... well I dont know if mplayer supports quicktime but can you reupload the quicktime trailer to somewhere else to see If I can try some other thing?
