Best method converting to mp4 with subtitles

[atsushi]

This isn't a direct question about MakeMKV but I was hoping other users might be able to answer my question. So I usually only use MakeMKV to backup my collection of anime. For dub it's simply using MakeMKV then using handbrake. I know that handbrake has a feature to add subtitle files but I really don't understand why I would do that when the mkv rip has already the necessary subtitle files but don't in the subtitle file format. The method that I came up with was using freemake software to convert my Anime MKV's to mp4 using freemake since it allows me to add the blu-ray subtitles easily. The problem that it's such a tedious method. Does anyone else have a easier method to convert to mp4 while also adding subtitles from the blu-rays?

If you MUST convert to MP4, handbrake is pretty good at that, and it will render PGS subtitles as well as anything.

An MKV file can use the PGS subtitles in a file, but that's a separate issue from MP4 comparability. MP4 can only have a couple of types of TEXT based subtitles, and optionally VOB-type (DVD type) graphically subtitles. Anything else has to be burned in. Handbrake will do that; Not sure what other converters will.
