Open Captions vs. Closed Captions

While both open captions and closed captions serve the purpose of providing textual transcription of audio content, there are some key differences between the two:

Open Captions:

  • Permanently visible and cannot be turned off.
  • Ideal for environments where closed captions are not supported.
  • Ensure accessibility in all viewing situations.
  • Do not allow for viewer customization.

Closed Captions:

  • Can be toggled on or off by the viewer.
  • Require support from the player or platform.
  • Offer more flexibility for the viewer.
  • Can be adjusted for font, size, and color.


Q1: What are the benefits of using open captions over closed captions?

A: Open captions ensure that everyone will see the captions without needing to toggle settings, ideal for social media videos or public screenings where accessibility is key.

Q2: Are there any video quality losses when adding open captions?

A: Adding open captions generally does not affect the original video's quality, although the final output can depend on the conversion settings.

Q3: Can open captions be edited once they are embedded into the video?

A: No, once open captions are embedded, they become part of the video and cannot be edited or removed.

Q4: How long does it take to add open subtitles to a video?

A: Adding open subtitles will re-encode the video, which takes some time depending on specific settings and computer configuration. But HD Video Converter Factory Pro features hardware acceleration that will greatly shorten the time.
