Can you mux subtitles and a .mp4 file together?

Nope, ssa is not supported in MP4 as soft subs

You would have to hardsub them to preserve the fonts/colors/effects

If handbrake doesn't support ssa sub hardcoding, you could use something like megui, ripbot

Yes there would be quality loss, unless you use a lossless codec - then there would be no additional compression losses (huge file sizes)

"Hardcoding" means permanently degrading the video , and the subtitles are always "on" because they are burned into the video

You probably have no other option if you want to preserve the fonts/colors/effects because most devices don't support SSA soft subs anyway , nor do they support lossless codecs

Handbrake supports hardcoding of SSA subtitles.

And so does XviD4PSP. But all this begs the question - why reencode and convert to MP4 when MKV is much the more convenient container?

Let's say, after completing the conversion to .mp4 and I use one of the programs you mentioned (MeGUI, RipBot) to hardcode the .ssa files to the .mp4 file.

You're suggesting reencoding once to get it to MP4 and then again to hardcode the subs? If it has to be done, do the whole thing at once.

Yes you can

First Install mp4box from

https://www.videohelp.com/software/MP4Box

Then Put the file and the subs in the same folder open cmd using Right click open cmd here or by typing cmd in the address bar and pressing enter

Then

mp4box -add nameofsubtitle.srt moviename.mp4

Thats all

Mp4box will create a new mp4file with subs
