Captions

DIY Captioning

Why caption video?

  • Required for accessibility for the deaf and hard-of-hearing
  • For anyone in noisy situations, when the audio quality is poor, or where noise isn't allowed
  • Make your video text searchable by search engines
  • Increase comprehension, especially for people with English as a second language
