Disregarding speed for the moment, it will if you 'fix' the quality,
via crf parameter for x264. Then you will get less file size for the
same quality. This is then a variable bitrate (VBR) encoding.

But if you fix the size, which means fixing the bit rate
(size=bitrate * videolength), you get better quality for the same
size.
