8 kbps is extremely low, even at 1 fps. That's equivalent to about 200 kbit/s at 25 fps.
And I would assume temporal difference between frames becomes very large at 1 fps, so compression is probably much worse than at 25 fps.
Anyway, what is holding you back from just using x264 with "--bitrate 8", preferably in 2-Pass mode, and see how it goes?
