Subtitling is the process of adding written text to a video or film to represent the dialogue, narration, or sound effects. It helps convey the spoken content of the video in a different language or provides a transcription of the audio for viewers who are deaf or hard of hearing. Subtitles are typically displayed at the bottom of the screen, synchronized with the audio for easier understanding.
Subtitling is important because it makes video content accessible to a broader audience, including non-native speakers and those with hearing impairments. It also improves engagement and viewer retention, as people can follow the content even in noisy environments or when watching in silence. Additionally, subtitles help search engines index video content more effectively, which can improve the discoverability of videos online, making it a valuable tool for SEO.
