[theora] recommendations for web video bit rates

[Christopher Blizzard]

Hey, everyone.  I'm sure this thread will generate some email!

Some people are working on a super-easy to use converter for people to 
be able to convert videos to Theora for the upcoming Get Video on 
Wikipedia push:

http://videoonwikipedia.org/

(Note that this isn't being pushed yet, and is pre-launch quality!)

For the converter one thing we'd like to be able to provide is a set of 
profiles for quality, bitrates and sizes that people can use to generate 
Theora videos.  (Michael Dale wants this for Firefogg, too.)

The number of bits that you need to allocate depends highly on the 
content - everyone here knows that - but we can come up with a rough set 
of guidelines that give a rough estimate for low/medium/high for a given 
size.  (Is it a linear scale, depending on width * height?)

I think that people have done this before, but just looking for 
experience and guidance.
