Compression artifacts are marginally visible if you freeze-frame, boost the differences in Photoshop, and zoom in? Who would have thought?

x264's psy optimizations are optimized for the case of actually watching a video. If you're not actually watching the video, just encode an all-black screen or something.

We will never optimize x264, ever, for the case of "not actually watching the video". It is beyond pointless.

If you want every single pixel to be perfect even if you zoom in, how about not recompressing the video?
