Comment (by miguelapg):

 Subtitles are positioned according to PAL dimensions by default, instead
 of placing them at bottom center as VLC or MPlayer do.

 Seems this was added at

 Why VLC drop subtitles in the usual place (bottom center), and even scale
 subtitles to fit video dimension, and ffmpeg doesn't do it?

 I think that this feature is not finished if ffmpeg is not following the
 standards of video industry, as ffmpeg is also a reference in the video

 I have attached an screenshot to show how subtitles are placed using a
 common set of parameters (even recommended by ffmpeg guides) ...

 -filter_complex '[0:v][0:s:0]overlay[vid]' -map '[vid]' -map 0:a
