Why Subtitles or Closed captions?
Adding subtitles to your videos makes it easier for your audiences to capture all the dialogues or commentary. It is also a great way to address those who cannot turn the volume up or may be hard of hearing. Our closed caption service enables users who are not familiar with the accent in the audio to be able to follow it without missing anything important. Our transcriptions also help in boosting the SEO ranking of your online videos.
