Subtitles are an important part of any video file and to play them with ease it is important to have a thorough knowledge of the same. The article below discusses the need for subtitles, types of subtitles, tools to add and edit them, and other related aspects.
Part 1. Subtitle Types
Majorly, subtitles can be defined as hard subtitles and soft subtitles in a video file.
Hard Subtitles: These subtitles are the part of the video file itself. Being the part of the video images, hard subtitles cannot be disabled, edited or turned off. Also known as hard subs or open subtitles, these are merged into the original video, no additional equipment or software is required for their playback.
Soft Subtitles: These subtitles can be defined as the independent stream which is originally not the part of the video file. Soft subtitles can be turned off or disabled when needed. Also known as soft subs or closed subtitles, these are separate instructions which come with a text and a time stamp for playback. The video player needs to decode and render the captions for the videos in case of soft subtitles and thus extra system power is required. Additionally, soft subtitles can be edited and the font, as well as its language, can be changed as desired.
There is also another categorization of subtitles where they are defined as internal subtitles and external subtitles. The internal subtitles are the ones which are included in the single video file with video as well as audio streams. The external subtitles, on the other hand, are separate files which are easy to edit and change.
Part 2. Why People Need Subtitles
