Small subtitles when muxing with Mkvmerge, Subtitle Edit, Aegis.

[gibarian]

I tried to mux a .sub on an .mkv file (original file was an MP4) but the results are comically small (when compared to the hardcoded ones):

That's how it looks on my Panasonic TV, and on SMPlayer. On VLC, it looks as it is supposed to:

I converted and edited the original .srt file with Aegis into an .ssa file, which I converted later (using Subtitle Edit) to the .sub file I used on the muxing process with Mkvmerge.

The mediainfo of the resulting muxed subtitle, is this:

Going over that data, I noticed that the stream size is smaller, when compared to other video files I have:

I don't understand what I am doing wrong here.

Your resulting SUP-file indeed seems rather small, in relation to its runtime. Have you tried setting a larger font size in the export window?

In mkvtoolnix turn off zlib let Compression = No extra compression, increase the font size
