Captions (Prerecorded) Transcript
Hello everyone. Today, we’re going to talk about captions. We’re also going to talk about its importance, benefits, types, and some examples. Now, let’s understand what captions are. Captions are a text version of speech and non-speech audio information needed to understand the content. Synchronized captions are necessary for the dialogues and other informative sounds for all the pre-recorded video content, like instructional videos, ads, and interviews with audio content.But why does it matter? Well, it is important that everyone perceives the information conveyed through dialogues and other important sound cues in the video. This ensures that the information communicated by the audio part of the video is available to people who cannot hear it. Captions must identify speakers, include spoken dialogue, and important sound effects, and capture non-speech elements.
Now let’s talk about who benefits from this. People who are deaf and hard of hearing. People who cannot understand the dialogues as they are non-native users. People with cognitive, language, and learning disabilities who can’t listen attentively. Those who are watching a video in a noisy environment.
Some of the examples are a keynote address of a CEO, a pre-recorded interview, a video blog where dialogues complement the visual information, and a baby elephant running through the grass to meet his mother.
This is the end of the video. Thank you for joining. If you like the video, do like and subscribe.
This success criterion intends to provide captions for all the videos that have audio in the form of dialogues, voiceover and other sound clues that combinedly convey information or help to understand the video. Captions, also known as subtitles or CC (Closed caption) in abbreviated form are most helpful for deaf, hard of hearing, deaf blind & users who don’t follow the video and depend on captions. Captions include not only the dialogue but also information such as speaker & non-speech information conveyed through sound which is meaningful like the claps of audience and laughter.
