Obviously, the non-real time nature of VOD captioning makes it a better candidate for trying it yourself, and most computer-literate professionals can probably do a competent job with VOD using one or of the tools described below.

Finally, live captioning only costs about $100-$150 an hour, plus extra for ancillary consulting services. If this is the first time you’ve produced live captions, you’ll want to involve someone who’s been there before. Second, the captions created via either technique must be deftly integrated into the life captioning workflow and adequately tested before the event.

There are multiple reasons why.įirst, there are two general techniques used for live captioning: One involves stenography machines, the other voice recognition, where a trained professional repeats what he or she hears into a microphone for the transcription.

Each caption should be composed of one or two rows and should be positioned in the bottom center of the caption region.Captions should be a verbatim representation of what is being said, although you may edit out unnecessary speech (um., ah., er., etc.).The following guidelines are from the Accessible Digital Media Guidelines produced by the National Center for Accessible Media. Beyond this distinction there are a number of general captioning conventions that are critical to know if you decide to caption yourself. Captions are also assumed to be in the same language as the video, so if an English-speaking video displayed a sign in English - a Stop sign, for instance - you wouldn’t caption that, but you would if you were subtitling the video into French.īasically, captions are a transcription of the spoken words and all important sounds, while subtitles translate the speech and text in the video. If you were subtitling the video, you would assume that all these could be heard by the viewer.

For example, if you were captioning a video, you would caption when background music played, when a shot rang out, when a car started in the background, or when the actors laugh or cry.
