What is the difference between captions and sub-titles?
- Captioning is the rendering of speech and other audible information in the written language of the audio. Captions are usually closed by default and to be used, must be turned on.
- Subtitling is mainly for translation of dialogue and certain onscreen elements in visible words.
- Captions were initially intended for the hearing impaired audience.
- Subtitles are mainly intended for an audience who do not understand the language of the dialogue.
- Captions move to denote who is speaking.
- Subtitles are almost always set at the bottom of the screen
- Captions describe sound effects and other dramatically significant audio.
- Subtitles assume you can hear the phone ringing, the sound of footsteps, or birds chirping.
Google has a product called CaptionTube which allows you to add closed captioning but was really cumbersome and i did not like it.
YouTube has a tool that allows you to upload a transcript for an option to add closed captioning to a video. YouTube uses speech technology to match the transcript to the speech on the video. After completed, the video will now have a CC button and also an interactive transcript button as well. Nice, i like this tool.
