Youtube's quality?

After having my tutorials or movement videos having a not so good quality, and seeing my frag video on HQ being way better than them and pretty decent for YouTube, I started wondering what were the right settings to upload to you tube...
So far I've done the following tests:
640x480 , x264, 10000 bitrate (max) ----> crappy
1280x1024, x264, 6000 bitrate ----> crappy *check Edit*
720x480, x264, 3000 bitrate, 90fps -----> almost like my vid
720x480, Xvid, 4000 bitrate, 90 fps -----> almost like my vid

Being the 2 last ones really similar and hard to tell the difference.

I believe widescreen resolutions work way better with you tube (my frag vid is also widescreen), and it might be even more important than the bitrate you use....
I think there is no need to go over 30 fps... that's enough.
Some videos look ridiculously good on you tube, but that's because people had found ways to avoid the youtube compressor (now fixed).
Anyway...anybody else that has any idea on how to get ideal quality? (specially on the HQ versions of youtube)

Edit: When I added &fmt=18 at the end of the link video looked really good D; The problem is that you can't see the "watch in high quality" option, but you could use anotattions to lead people to the HQ! . 800x600 might be a good res.

I have often wondered because I have uploaded a few vids and it seems way crappy soemtimes but others it seems decent. I used XVID and the clips being 30sec long were about 50-100mb so were decent quality but ended out looking like complete crap. I have not uploaded any vids for ages.

any joy?

well... once I read something like "if you want good quality, upload the best quality you have to you tube"
That's what I'm doing.
Like ...if you do a frag video, compress 3 times our avi.... once in x264 for people to download, another one with xvid for people to download too, and a third time with a high bitrate (10000 if you can) using x264, and upload that one to youtube. That's what I did with my TF2 scout jumping video.
There shouldn't be much trouble for all you that have fast internet connections (come on I upload at 10 kb/s ... )

can you keep it under 100 megs doing this? especially with a 10000 bitrate

you tube changed that, you can now upload till 1 gb, still 10 minutes top though ( it's a bit flexible, you can upload a 10:30 video)
