How to specify subtitles codec in ffmpeg cli?

[Anonymous543]

I was cutting some part of video with ffmpeg cli
without rencoding
Original video streams was
Stream 0 : video hevc
Stream 1 : audio ac3
Stream 2 : Subtitle ass

So I used this code
ffmpeg -ss 00:25:00 -i input.mkv -t 60 -c:v copy -c:a copy output.mkv
It gives this result
Stream 0 : video hevc > copy
Stream 1 : audio ac3 > copy
Stream 2 : subtitle ass > ssa

So with that code it converts subtitles format

Just like we specify
-c:v for video codec
-c:a for audio codec

How we can specify subtitles codecs?




Btw I did lil research and found that
ffmpeg -ss 00:25:00 -i input.mkv -t 60 -c:copy output.mkv
This copy all streams including subtitles also
Stream 0 : video hevc > copy
Stream 1 : audio ac3 > copy
Stream 2 : subtitle ass > copy

But just wanna know how we can specify subtitle codec in ffmpeg?

ass = ssa

g.e.

-c:s srt

(where srt is the codec)

No I checked on Google

ass = Advanced SubStation Alpha (ASS) is a script for more advanced subtitles than SSA. It is technically SSA v4+

ssa : SubStation Alpha (or Sub Station Alpha), abbreviated SSA, is a subtitle file format created by CS Low (also known as Kotus) that allows for more advanced subtitles than the conventional SRT and similar formats. It is also the name of the popular, now discontinued tool used to edit subtitles.


Both different

you can try to copy all streams and metadata:

ffmpeg -ss 00:25:00 -t 60 -y -i %1 -map 0 -c copy -f matroska %~n1_60.mkv

[jagabo]

-c:s copy

or

-c:s ass
