staigerpaip,
you're right, one possible problem is that with high quality settings as we use, mencoder could encode the film with average bitrate less than desired. That's why I asked how did it look (I'm afraid this is not bigggt problem). But in this case, it would be encoding at higher quality possible at a given resolution... is that bad?. I think no. Yes, the solution is raise the resolution, so mencoder will need more bits to encode the film.
But I don't think we're using the higher quality possible. Using trellis with cbp, or mbd=2, would be using even higher quality. I guess you refer to the fact we already use min quantizers at minimum possible. But if the whole film is encoded with quantizers=1 and average bitrate<desired... that means we can make it at a higher resolution (or add more noise,...)
