Subtitles
From FansubWiki
In subtitles term, a video is generally classified as one of the following:
- RAW - the video does not contain any subtitles.
- Softsub - the video has an accompanying subtitle that can be turned off. They are either carried within a video container (sometimes referred to as embedded) or as a separate file.
- Hardsub - the subtitles have been rasterized and burned into the video. When you play the file, the subtitles will show up, regardless of whether you want them to or not. The subtitles are essentially part of the video.
