Auto captions, also called automatic subtitles, use speech-to-text to write out what people say in a video and show it on screen in time with the voice. Social-style captions often highlight each word as it is spoken. Captions can also be exported as subtitle files, such as SRT or VTT, for video players and websites.
Many people watch social videos with the sound off, so captions keep them watching. They also help viewers who are deaf or hard of hearing, and anyone watching in a second language. Speech-to-text can mishear names and unusual words, so the words still need a quick read.
Say a fitness coach at a studio called Peak Pulse Fitness films a one-minute tip on her phone. Captions turn it into a clip that works in a silent scroll, and she fixes the one exercise name the captions misheard.
In aiKit, Video Kit makes word-by-word captions in 31 fonts and 7 looks, with any word editable, and can show captions in another language. Screen Recorder adds captions in 19 languages to its links, and Transcribe & Summarize downloads SRT and VTT subtitle files.
