Wondershare DemoCreator
Essential demo-making tool that helps learners, educators, freelancers and gamers to take idea-sharing to the next level.
Have you heard the term ‘auto caption’? Ever wondered what it means and how you generate them? You must have seen several videos with subtitles correctly and precisely synched with the dialogs that the artists speak throughout the film. Although wrongly (explained later in one of the following sections), those subtitles are sometimes also referred to as closed-captions or open-captions or most commonly, simply captions. In other words, the terms ‘subtitles’ and ‘captions’ are often used interchangeably.
The captions of the audio in a clip can be typed manually or generated automatically by an integrated tool or a dedicated auto subtitle generator app designed specifically for the purpose. Depending on the nature of such an app, it can be installed on your computer or could work online.
Part1 What Is Auto Caption & Subtitle
When talking about the auto caption, as explained earlier, the term means the captions that have been automatically generated using some auto caption generator online or offline app. With such an automatic caption generator, you don’t have to manually type the text and synchronize the content with the video using a resource-intensive post-production application.
Captions vs. Subtitles
While the purpose of the auto caption is to make the viewers read the text if they are unable to hear the audio, the subtitles, in many cases, are the text translations of the audio into a different, understandable language.
When talking about captions, they are of two types, namely:
Closed Captions
These are the time-stamped texts that are stored in a separate file (usually with the *.srt extension) that is automatically accessed by the player when the video is played. Closed captions can be enabled or disabled according to the viewers’ needs, and if the player allows, the format of the text can be modified as well.
Open Captions
These captions are not stored in a separate file but are burned into the video itself. Because of this, they cannot be enabled or disabled manually, and neither can they be formatted manually.
