Subtitling

Subtitling is referred to as the translation of audio (source) language content (usually with video images). Subtitling is commonly used by the entertainment industry to broaden the market of their content to other countries that speak a different (target) language. The translated text (subtitles) is superimposed on the screen and appears at the bottom (or sometimes top) of the video content.

Subtitle

A subtitle is typically defined as the actual translated text on the video screen (usually in movies or television programming). It can also refer to an explanation of a written title in the video content. This is common when written content is photographed (e.g., a sign) and is a pertinent to understanding the video.
