Captions belong in the production plan for online video

An online video can reach a large audience while remaining inaccessible to people who cannot hear its soundtrack. Captions help convey speech and relevant sounds, and they work best when planned as part of production rather than added hurriedly at the end.

W3C's accessibility guidance distinguishes the needs of different kinds of media. A video with meaningful visual information may also require description, while a transcript offers another way to access its content. One format does not automatically perform every accessibility function.

Accuracy is an editorial issue as well as a technical one. Names, numbers and changes of speaker can be distorted by automatic transcription. Timing and readability influence whether a viewer can follow the material comfortably. Reviewing the output against the recording helps prevent errors from becoming part of the published story.

Planning early makes these tasks easier to assign and budget. Scripts, clean audio and a clear account of important visual details all support the process. Accessible publishing broadens the ways an audience can engage with journalism and other media, while creating a more dependable experience for viewers watching in noisy or quiet environments alike.
