Jul 29, 2014 Text subtitle such as SRT, SSA, is saved as text in the video, when playing the video file, you can change text font, size and color easily. However, your system need more space to store font files, and need more CPU power to render text into image on the screen. SRT is the most commonly used text subtitle format. It is very simple and easy to use.
- May 19, 2021 Although it is text-based like SRT subtitles, MKS doesn't possess as good compatibility as SRT, and is actually not quite friendly to most mainstream platforms and video formats. To be able to add MKS to your movies correctly with any third-party tool, or adapt it for some further use, converting MKS to SRT is a solid plan.

PGSsubtitles consist of a series of bitmapped images and aren't actually 'text' at all. PGS subtitles on a blu-ray are 1920x1080px resolution images, for instance, which is a 16:9 aspect ratio. When making the blu-ray, black letterboxing is added to the video so that it ends up as a 16:9 ratio 1920x1080px video when rendered. When content is ripped from a blu-ray, the letterboxing is typically removed so that only the video itself remains, but if you ripped Blu-ray to lossless MKV, the PGS subtitle will be preserved.
But the thing is that even you kept Blu-ray PGS subtitle in MKV container, you might also lose subtitles when playing this MKV file in VLC, WD TV Live box, etc since many media players couldn't support PGS subtitles. In most cases, you need to rip MKV PGS subtitle to SRT subtitle on the fly. SRT subtitles are text files and don't suffer from the same sort of issue.

Useful Tips
In windows I have been using the great SubtitleEdit to do this task.It runs well (with some small display glitches) under wine, although I only opened the subtitle without the video.
Recently I found a native, faster way to convert these files using mkvextract.
First you have to
identify the track you want to extract.You can use the
mkvmergetool for this:mkvmerge -i 'filename.mkv' or
mkvmerge -i 'filename.mks' (for subtile only files)
The output for a mkv file will look similar to the example below:
Track ID 0: video (MPEG-4p10/AVC/h.264)
Track ID 1: audio (DTS)
Track ID 2: subtitles (SubRip/SRT)
Track ID 3: subtitles (SubRip/SRT)
Chapters: 32 entries
Form the output of the command you need to
identify the Track ID of target subtitle track you wish to extract.If you already have the MKS file use the following command to convert to SRT:
mkvextract tracks 'filename.mks' 0:filename.srt
0 is the target subtitle track of the MKS file.
If you want to
How To Convert Mks To Srt
extract and convert one or more subtitle tracks directly form the MKV file you can use a command similar to the following:mkvextract tracks 'filename.mkv' 2:sub1filename.srt 5:sub2filename.srt
where 2 and 5 are the target subtitle tracks.
There is one more important aspect to note:
Only subtitle tracks of the type S-TEXT/UTF8 will be written as SRT files. The output file type is dependent on the track file type as stated in the mkvextract man page (link above).
The mkvmerge and mkvextract tools are part of the mkvtoolnix
