Part 1. Best Free Open Captioning Software Download

Open captions or hard subtitles are burned to the video or stream and in view automatically along with the spoken audio. Open captions cannot be turned off. This is the biggest drawback of open captions compared to closed captions, but they do have their value:

  • Easy to use. Open captions will display automatically and don't require any technical ability to display the captions.
  • Fit any display and players. Open captions are playable on the largest range of computers, and operating systems without requiring special functionality.
  • Suitable for web uploading. Open captions are a good option any time you don't have control of a closed caption feature. For example, when uploading to a platform that won't provide a closed caption option, it makes sense to hard-code captions to the video file.
