You should not only measure quality at some random bitrate but to make
them comparable you should measure it at same/equal bitrate (because
to make quality itself same/equal is much harder or mostly impossible
task). Or you can measure quality and bitrate at few points of
quality/bitrate curve and compare this RD curves (but this RD curves
should be overlapping to be comparable).
