Hard captions, also known as hardcoded captions, are subtitles or captions that are permanently embedded into a video. This means the viewer cannot turn them off or hide them.
Understanding Hard Captions
Unlike soft subtitles or closed captions, which are separate tracks that can be toggled on or off, hard captions are integrated directly into the video frames themselves. They become a visual element of the video, similar to any other graphic or text overlay.
Key Characteristics
- Permanently Visible: The defining characteristic is their constant presence. The viewer has no control over their display.
- Part of the Video: Hard captions are encoded as part of the video stream, making them inseparable.
- No User Control: Users lack the ability to customize their appearance (font, size, color, position) or language, as the caption style is fixed.
Examples of Hard Captions
- Older Movies/TV Shows: Often found in older media formats where soft subtitle technology was unavailable or not widely used.
- Foreign Films with Dubbing: Sometimes hard captions are used to display original dialogue while an audio dub plays.
- Edited Video Clips: Frequently used in shorter video clips shared online, especially on social media platforms, to ensure captions are always visible.
- Tutorials and Educational Videos: Hard captions can guarantee accessibility for all viewers, regardless of platform or player capabilities.

When to Use Hard Captions
Hard captions are most appropriate when:
- You need to guarantee accessibility on all devices and platforms.
- You want to ensure that captions are always displayed, regardless of user preferences.
- You are distributing short video clips where ease of viewing is paramount.
- You don't want to rely on viewers having the correct software or knowledge to enable captions.
In conclusion, hard captions are permanently embedded subtitles or captions that are always visible and cannot be turned off by the viewer.
