Well...Resolution is base on your cam, not the software. So if your camera can only handle 16fps at 16x120, get a new cam.
I use the Logitech software that came with my quickcam pro. Pretty good with a slew of compression codecs.
Also, look into Ulead Media studio or if you know what you're doing, Adobe Premier. Those are both good starts, or Logitech, if that's the kind of cam you have.
