Use text instead of srt, otherwise the output font sometimes becomes huge.
Need to change -c:s srt subtitle.srt to -c:s text subtitle.srt.
ffmpeg -i -map 0:s? -c:s copy # To copy a Subtitle. ffmpeg -i -map 0:s? -c:s srt # To convert the Subtitle to srt. ffmpeg -i -map 0:s? -c:s text # To convert the Subtitle to text. ffmpeg -nostats -loglevel 0 -i subtile.ass -y -c:s srt subititle.srt # To convert ass subtitles to srt.
NOTE: The srt conversion, can result in huge text.
Use:
-c:s text
Instead of
-c:s srt
NOTE: SRT, as opposed to ASS, does not contain style information.
