I checked what Android does in their camera application. 
Basically they seem to use an average bitrate of 12kbps in 1080p, 8kbps in 720p and 5kbps in 480p.
We agreed that we would try to do the same.

However, once I pass the correct bitrate setting down the stack from
qtubuntu-camera, it seems that at some point that setting gets lost or
ignored.

Jim Hodapp is looking into why this happens, since he's working on that
part of the stack. So far it seems that the settings is making its way
down to the level of the media framework, and he is looking to find if
it gets passed to the video codec properly.

Title:
  480p and 1080p video appear to use the same bitrate

Status in Canonical System Image:
  In Progress
Status in camera-app package in Ubuntu:
  In Progress

Bug description:
  I just recorded two 10 second videos of the the same object using my
  Nexus 4, one using the 1080p setting and the other 480p.  Both videos
  came out at roughly 8MB, each with approximately a 6.3 Mb/s video bit
  rate and 96 kb/s audio bit rate.

  This seems a bit weird to me: the only reason I can think of to offer
  multiple resolutions is to let the user pick the quality / storage
  space trade off they want.  If the lower resolution videos take up
  just as much space as the high resolution ones, then this doesn't make
  sense.

  I am running build 143 on a Nexus 4, which looks to have camera-app
  3.0.0.516 installed:

      current build number: 143
