Edit font of srt subs in mkv

[MicoMaco]

Hello!

Is there a way to set the font and character size in softcoded srt subtitles in mkv? I don't see an option in mkvmerge.

SRT (SubRip) format is textual only: you can't set either font or size, they are chosen at the player level.

Thank you very much for this clarification.

Thank you very much for this clarification.

If your player can handle idx/sub subtitles, and the .srt is Ansi, you can create idx/sub files choosing font, size, colors, border thickness etc. using AviAddXSubs freeware.

There may be others that can handle UTF-8 or Unicode subs if that's a requirement.

AviAddXSubs is mainly for embedding XSubs in divx but it makes very nice idx/sub files with YUV color option switch. My WD set top box has lousy options for .srt so many times I'll make custom idx/sub with AviAddXSubs for thicker borders, nicer looking and larger fonts etc..

What do you use to play the video? As mentioned if you change the format your player might ignore them.

Subtitle Workshop is another program for editing and saving subtitles in different formats, and it's free. You'll probably need to use something like MKVCleaver to extract the subtitle track so it can be opened with Subtitle Workshop.

i've read/search the srt format as well and there is no support for changing font size, color.... so with using Handbrake it is a real bummer but ffmpeg does support subtitle format but it looks like you have to reencode every time you add a subtitle

"`-scodec codec'
Force subtitle codec ('copy' to copy stream).
`-newsubtitle'
Add a new subtitle stream to the current output stream.
`-slang code'
Set the ISO 639 language code (3 letters) of the current subtitle stream.
`-sn'
Disable subtitle recording.
`-sbsf bitstream_filter'
Bitstream filters available are "mov2textsub", "text2movsub".
ffmpeg -i file.mov -an -vn -sbsf mov2textsub -scodec copy -f rawvideo sub.txt"
