What is captioning?

There are two primary types of captions: those that are added to videos after they are recorded (post-production captions), and captions that are used during live events (live captions/transcription). The key to captioning is that quality is important. Bad captions are worse than no captions.

Captions should be:

  • Accurate (~99%)
  • Synchronized to the audio
  • Readable
  • Positioned on screen so they do not block important information
