How do I Mux subtitles into MP4 as a plain text

[A700]

hey,guys
I've been using MP4Box to mux .srt subtitles into MP4 Files
but the default subtitle size is too small [18pt] and the font is lame [serif]
so I wanna mux the subtitles into MP4 files as a "Plain text" so that I can change the subtitles style from my player directly
how can I do that ?

Does your player support external subtitle files, with the name of the subs the same as the video?

video.mp4
video.srt

With subtitles, some stand-alone players have better support for external files than they do muxed subtitles.

Perhaps use Subtitle Edit to convert the SRT to Timed Text format (just change the Format at the top of the screen from
.srt to Timed Text) - set the font/size you want - and mux those to your MP4.

How can I put a black outline for the text ?
