Can't see your subtitles on the screen? Can't see your subtitles on the screen?
Sometimes you import a subtitle file which starts from 01 hours or 10 hours, based on the original video TC.
However, the default Media Start TC of every loaded video is set to 00:00:00:00. In order to set a different base time clock for your video, go to Media menu --> Open video/audio file --> set Media Start TC to the time code value of the first video frame.
