Which level vs data rate vs screen size is going to give you best results given your server setup? Do you need to use a 2 pass encode, or are your raws clean off that it's wasted render time? Is a lower level, higher resolution encode giving you better stream times and bandwidth savings vs a higher level, lower resolution?
Love to help you through some testing if you want to get a hold of me, but with mp4 format especially I would be wary of broad stroke calculations.

Thanks for the info.
I'm planning to use a standard size player for the web (720x480/405 or 854x480), and 320x240 for slow connections and mobile devices.
Render time is not an issue, since I have dedicated machines for that, so I will stick with 2 pass encoding.
I'll run a few tests and then maybe hit you up for a critique and advice.

h264, 640x360 (360p) @ 650kb
H264, 854x480 (480p) @ 1000kb
H264, 1280x720 @ 2022kb
H264, 1920×1080 is being "tested".
Can't remember what the default is for sure but I think it's one of the first 2 as opposed to the legacy FLV they still have as well
Course they're also encoding videos in VP8 now for the HTML5 beta version of the site.
