Video Encoding Bitrates

Heyas

Kind of a Video-Wibble, as i'm just curious what are your (most) prefered video encoding bitrates.
A video comes with an audio and video stream, and to me at least, the bitrates vary upon the dimension/resolution of the video.

Desc	Resolution	Audio  Video
------------------------------------
* clip	320x240 	a128 v256
* vhs	640x480 	a128 v384
* dvd	720x576 	a192 v512
* hdr	1280x720	a192 v768
* fhd 	1920x1280	a256 v1024

So this is about the average i'm using on my videos, and i'm interested in yours.
Cheers

I'm currently processing a 720x576 video just using ffmpeg defaults (using libx264) and its running at just under 1Mbits/sec.
