Comment (by mimac):

 I will direct the question to libx264 project, sorry for misunderstanding.
 For the size guarantees, I made tests with constant quality settings and
 thought that results would comply with what
 [https://trac.ffmpeg.org/wiki/Encode/H.264 page about encoding] states:
 ''Similarly, for constant quality encoding, you will simply save bitrate
 by choosing a slower preset.''
