For me the clip lighthouse_lossless.mp4 is interesting because of the sky -- it is challenging to encode this clip at low bitrates to be not annoying if you look at the sky. There are not sharp details -- it is about the gradients. PSNR is not perfect but for the sky it is OK.

For me at low bitrates aq-mode 1 is the least annoying, for medium bitrates aq-mode 3 is OK too. The default aq-mode 2 is not the best at low and medium bitrates with this clip (for me).
