In the context of anime, “s-sub” typically refers to “soft subtitles.” Soft subtitles are a type of subtitle file that can be turned on or off by the viewer, as opposed to hard subtitles, which are permanently embedded into the video.
Soft subtitles allow for more flexibility in viewing, as they can be adjusted for different languages or turned off completely without affecting the original video. This is particularly useful for anime fans who may want to watch a show in its original Japanese audio with subtitles in a different language, or for those who prefer to watch without any subtitles at all.
Soft subtitles are commonly found in digital formats like MKV files, which support multiple subtitle tracks. They are often used in fan translations and releases to provide viewers with options based on their preferences.
In summary, “s-sub” indicates that the anime has soft subtitles available, enhancing the viewing experience by allowing customization of how the content is presented.
