What Are Closed Captions?
Closed captions are text representations of the audio track in a video, designed specifically for viewers who cannot hear the audio. They are "closed" because they exist as a separate file that the viewer can toggle on or off in their video player.
Because they assume the viewer cannot hear anything, closed captions transcribe the spoken dialogue in its original language while also describing essential non-speech audio, such as sound effects or musical cues.
What Are Subtitles?
Subtitles are text representations of the spoken dialogue in a video, designed for viewers who can hear the audio but do not understand the language being spoken.
Because they assume the viewer can hear the background noise, subtitles focus entirely on translating the dialogue. They typically exclude descriptions of sound effects or music unless it is crucial to understanding the plot.
Closed Captions vs Subtitles
The fundamental difference lies in the intended audience: closed captions are for those who cannot hear, while subtitles are for those who cannot understand the language.
| Feature | Closed Captions | Subtitles |
|---|---|---|
| Intended Audience | Viewers who cannot hear the audio track | Viewers who do not understand the spoken language |
| Dialogue | Transcribed in the original spoken language | Translated into the viewer's language |
| Sound Effects | Included to provide full context | Excluded, as the viewer can hear them |
| Common Use Cases | Accessibility, silent autoplay on social media | Foreign films, international audience reach |
When Should You Use Each?
You should provide closed captions if you want to make your content accessible to all viewers, especially for compliance with accessibility standards. They are also incredibly useful for modern social media consumption, where many viewers watch videos with the sound muted on their mobile devices.
You should provide subtitles when you want to expand your audience internationally by offering your content in multiple languages.
Creating Subtitle Files with Konthora
Regardless of whether you are displaying captions or subtitles, video players require a standalone text file containing the dialogue and precise timing information.
You can create these files automatically using the audio to text tool. By uploading your media file, the system will generate a speech to text transcription with embedded timestamps.
Once processing is complete, you can export the transcript as either an SRT or VTT file. Because Konthora creates standalone subtitle files rather than permanently burning the text into the video, you retain full control over how they are uploaded and displayed on platforms like YouTube.
