p.s. the original video is in this link http://www.nasa.gov/multimedia/hd/HD...archive_1.html, the fifth paragraph.
Well td_ref, it's rather complicated.

The first thing we're dealing with here is the limited capabilities of the vBulletin software that MCM runs on. Some sights using vBulletin allow users with html experience to customize the way things are displayed. MCM has a core set of "tags" that can be used to present text, photo's and videos, but it's very limited. CC has given us tags for several video hosting services, but the Chinese government keeps banning them (I think this now includes Viddler) so he's fighting a battle that can't be won. It would be cool if we could have a little more html or iframe power in our posts, but it may cause problems for CC.

Regardless of which video hosting sight people choose, all of them change your video before streaming it. For instance, you downloaded a 47.0 MB 1280X720 HD video that was encoded as an .mp4 file and then uploaded it to youku. They used a different .mp4 encoding method and shrunk your video down to a 3.7MB 672X378 file. So when you go to youku to watch your video, you are seeing a much smaller version than what you uploaded. It still looks good, but it is very different. They also display it in their stupid 4:3 format, so you have the black space at the top and bottom.

When I get a massive HD video file out of my camera, I can transcode it before uploading to a video hosting site. For example, 640X360 is a beautiful size for streaming high quality HD footage. I can easily upload 2 minutes of footage in less than 50MB. Half the problem with uploading is bandwidth, the other half is youku….their servers suck. That 50MB file upload to Vimeo via my proxy server only took 17 minutes, I direct uploaded it from my computer in Taipei in 4 minutes.

I really appreciate your input and time. I would be happy to post via youku, but I can't understand the Chinese interface and, as you mentioned, uploads take a very long time.

Cheers!
