Despite the fact that "placebo" never gives any noteworthy improvement over "veryslow" (it only is a LOT slower), using slower settings in the first pass of a 2-Pass encode doesn't make much sense. If at all, you would be using faster settings in the first pass and slower settings in the second one! And actually that is what x264 does automatically for you: x264 will overwrite your settings with "fast" settings, when you set "--pass 1" but do not set "--slow-firstpass" too. And it's good that way.

So after all, what you'd want is something like:
Code:
x264.exe --pass 1 --preset veryslow
x264.exe --pass 2 --preset veryslow
Note: We use the identical preset for both passes and let x264 speed-up our settings in the first pass automatically.
