CyberLink PowerDirector lets you extract the subtitles from an MKV file, importing them directly into the Subtitles Room. This allows you to manually edit the subtitles, and then re-produce the file with the updated subtitle text.
To extract subtitles from an MKV file, do this:
1.Import the MKV file into the media library, and then place the video file on the timeline.
2.Right-click on the file, select Extract Subtitles, and then the language of the subtitles you want to extract.
3.CyberLink PowerDirector will extract the subtitles into the Subtitle Room.
Once you have extracted the subtitles from the file, you can then edit the subtitle text. See Editing Subtitles for more information.
