Subtitles in screenshots

How can I get soft coded subtitles to show in my screenshots?

windows 7
standard pack
havent tried anything, usually I would go to options>playback and there would be an option to use sub rendering in there but its not in there.

MPC-HC options > Playback > Output > Subtitle renderer > Select VSFilter

sorry about really long reply been busy and forgot I made this post, but now I cant add a separate .srt files to my videos.

.srt files are loaded automatically by VSFilter if you give them the same name as the video file.

Example:
movie.mkv
movie.srt

You can also use language tags, like this:
movie.en.srt
movie.de.srt
movie.english.srt
movie.deutsch.srt
