warning : All this is IIRC and unchecked
* "key frame" is an uncompressed frame (image) in the resulting file. "key
frame rate" then could be "put a key-frame every [n] frames" or "every
[time]".

* "data rate" setting is a way to limit the size of the file in a particular
but very useful way. If your anim is to be read from a slow device (eg 1x
CdRom), you are limited by the transfer rate of the device. If the anim
exceed that data rate, it will stutter. "data rate" makes the compression
amount vary locally in the anim to guarantee the resulting file never
(nowhere / nowhen) does exceed the data rate.
