Interesting. But IMO, what BD3D2MK3D does makes sense, because if the user selects psnr as the Tune option in the GUI, then that means that the --psnr parameter must be specified too, because if I understand correctly, disabling psy without enabling psnr (or ssim) doesn't make sense.
In the other hand, it makes sense to specify --psnr without the psnr tune, just to have a feedback about the quality (although it will not be perfectly correct) and without disabling the psy optimisation to keep the encoding for the final MKV. It's what Frank does. To do that with BD3D2MK3D, it is sufficient to add the --psnr argument manually in the additional options field.
Correct?
