I uploaded a 1080 test video to youtube. The source was from www.v6rz.net, an mpeg2, 1080p, 29.97fps file. The youtube player shows a 1080p version available, but the Firefox extensions download helper and download flash and video only show max 720p versions. The video is here http://youtu.be/WJZuScUC0qw
Why can't I d/l the 1080p version? I specifically wanted to test something.
Btw, the video came down as 16:9, 720p, 209Kbps, avc High@3.1, cabac/1 ref, 192Kbps audio @ 44.1KHz, AAC (lc).
Is there an up-to-date table of resulting video formats?

thanks for the tip! Yes, this software gave me more option to download the video, including 1080p. So much for the firefox extensions.
I can download the 1080p version using Firefox with the Youtube Video and Audio Downloader extension.
https://addons.mozilla.org/en-US/firefox/addon/youtube-video-and-audio-dow/?src=apiThey that give up essential liberty to obtain a little temporary safety deserve neither liberty or safety.
I just tried that one as well, but couldn't get the 1080p version. Could you tell me the steps you used to achieve this? I find the program a little confusing.
Click on the "2" at the bottom of the orange downloader window.
Ok, finally getting somewhere. The problem was that I didn't restart *all* my Firefox windows. And of course, I lost all my tabs in the process (Restore previous history just gave me the "Install extension" tab).
I can only get the 1080p stream as video only. I think that's why many of these extensions don't work; apparently only up to 720p is available as a combined video/audio. In order to get 1080p, I have to download separate audio and video streams, then install ffmpeg to have them combined. Also, you only get the 128Kbps AAC audio this way - the 720p stream has 192Kbps audio, so ideally you'd download the 720p combined, 1080p video, then somehow mix and match them.
But for testing what the average viewer gets presented, the default 1080p combo is what I want.
The audio and video has to be combined, because they are sent separately. There is no other way, the flash player does this too. The 720p video source is sent with 192k by the choice of YouTube. I checked the flash player, and 1080p plays with 128k also. So, that is how they are sending it. You could easily remux the audio if you'd like.
