ffmpeg - Subtitles - Font too large

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.

Map a Subtitle

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.

  • Therefore, it is recommended to use the text conversion

Use: 

-c:s text

Instead of 

-c:s srt

NOTE: SRT, as opposed to ASS, does not contain style information.

  • The subtitle font and font size will need to be configured in the playback software.
  • An example of srt line:
    00:05:55,160 --> 00:05:59,080
<font size="55">subtitle text</font>
