Just add -vf format=y8,scale to those colour rips and you have encoded
a B&W film. Unless someone broke the encoder very severely they will be
no worse than the colour ones. So we can then conclude, that if you have
a problem with some films, it is not because they are B&W. It might be
that those films e.g. contain much more noise and were filmed with a
far more shaky camera, in which case you might try some denoising but in
general will always need a far higher bitrate.
