The emergence of online video sped up this evolution exponentially, with each video platform and editing application seeming to have its own official format.Īlthough there's no universally accepted captioning formatting standard, some, such as SRT and SUB, are more mainstream than others. Over the years, as media formats evolved, so did caption formats. In some countries and on most social media platforms, including captions in all video content is mandatory.Ĭaptions have been in use for broadcast video since 1970. They allow people with hearing disabilities to understand and enjoy the dialogue in the same way that others do. Captions and subtitles typically appear as dialogue or text at the bottom of the screen in films, television programs, video games, or other visual media. Captioning is turning the audio content of a video into text and displaying it on a screen or monitor.
