You get no control over the quality bitrates, only resolution and framerate.
I don't own a K-3 but I do have a K-01. With the K-01 you do have some control over bitrates.
Simply chose which video IQ from the quick menu (info button).

Using the different IQ setting I shot three test files in turn for 5 secs each which gives these results:

*** = 23.5 Mbps / 5 second file 16Mb / Overall bit rate : 24.7 Mbps
** = 16.0 Mbps / 5 second file 11Mb / Overall bit rate : 17.2 Mbps
* = 8 945 Kbps / 5 second file 6Mb / Overall bit rate : 10.2 Mbps

I have found the lowest IQ setting while giving the smallest file does not really equate to less in video image quality when played. At least I can't see the difference.

I'd be very surprised if the K-3 didn't have similar control.
Good point on this. I was referring to the fact that the *** max quality file is not particularly good quality when compared to comparable products from other brands. (The Pentax video bitrate is low compared the competition even straight out of the box, forgetting about the hack firmwares options on other brands that allow incredible control over multiple different variables.)

What you have described is spot on though and was worth mentioning.
