What people tend to forget is that you are sending YouTube a master for them to compress; therefore, send the highest quality you can, that fits within their limitations. YouTube.com is well know for being the busiest video-sharing site, but unfortunately, YouTube uses the much older Sorenson Spark codec for their video encoding. This was the “improved” video format for Flash 7 but is based on the very old H.263 video conferencing codec. Even when new, this was an old, inefficient codec.
Many people send YouTube an already compressed video, and are disappointed when they see the quality that results on YouTube. That’s because most of the information was first thrown away by the encode before upload, so there was little quality left to be encoded to Flash 7.
Thanks to Phil Hodgetts for this guest tip.
This info is a little outdated. YouTube has changed the compressor to H.264 and they allow files up to 1GB.
Here is some more info from YouTube

Not exactly.... the 1 GB is ONLY allowed if you use their batch loader application (if using the web-based form the 100 MB limit still applies).
PLUS.... you need to have a special account to do this… and it ONLY works on Windows
the rules still apply…
As far as H.264… we mentioned that.... they compress to both formats.... Flash for the site… H.264 for Apple TV and iPhone delivery.

Actually, they are rolling out H.264 on the site, not just for Apple devices. (It’s the “high quality” option you’ll see below certain clips.) Recent versions of the Flash 9 player support H.264.

Hence the line that says
“(although they’ve started to also do 640X480 in H.264). “
I realize all this guys… the point of the article is that no matter HOW you encode… YouTube RE-ENCODES…
I know this having done video or Google corporate. Their system will not (and CANNOT) accept a video even at right specs. Everything submitted is re-encoded.
Thats all. Okay?
Posted by Richard Harrington on 05/21 at 05:28 PM
My understanding was that you could provide a file that fit their maximum specs and that they would NOT re-encode if you were correct codec, size, and within datarate/time/filesize limits - I thought that was the best way to go…

Nope…
We were hired by Google directly for a multi-video project… and we asked to do JUST that....
But nope… their system re-encodes… even if it exactly matches their specs.

Curious that you say that you have to use the batch uploader to upload files bigger than 100Mb - I have uploaded several videos by individual web form that have been well over 300Mb a pop. On Mac OSX. I did use the batch uploader, but found that the uploads crawled down to about 20k, but individually uploading files they went at a nice fast 55k.
Either way, I’ve been doing this for the last two months. I’m required to upload a local soccer serial and I always export to MJPEGs that are a few hundred Mbs each and upload each show in two sections. At least seven hundred Mb is uploaded between the two sections, and YouTube has always let me do this, either with the batch uploader or without, and I don’t have any kind of special account (as far as I’m aware)

“What is the YouTube Uploader?
The YouTube Uploader is a way for you to upload video files larger than 100MB or upload many files at once. To use the Uploader, you’ll need to download our application to a Windows computer.”
Now even though it says that… a Mac link is here for a beta version of uploader – http://youtube.com/multifile_installer
But it still says
“Each uploaded video is limited to 10 min and 1 GB”
Truth be told.. you can go a littlel over 10 minutes… Longer videos have generally been.
There are a few loopholes for older accounts… director pages, etc. But none for anyone recently.
“Your video is limited to 10 minutes and 1024 MB.”
