Open captions are text burned directly into the video itself
Open captions are words displayed on the video frame that cannot be turned off by the viewer. Unlike closed captions, which a viewer can toggle on and off, open captions are part of the actual video file — they appear the same way for everyone watching, whether on a phone, a website, or a TV.
When you watch a movie trailer on YouTube and see dialogue written at the bottom of the screen with no option to hide it, that is an open caption. The text is embedded into the image itself during the video creation or editing process. Once it is there, it stays there for every person who watches that video.
Open captions serve different purposes than closed captions. They are often used for stylistic reasons — to show a character's thoughts, to display text messages or emails on screen, or to translate foreign language dialogue. They are also used when the video platform or player does not support closed captions, or when the creator wants to may support captions appear regardless of viewer settings.
Key Takeaways
- Open captions are text permanently embedded in the video image and cannot be turned off by viewers.
- Closed captions, by contrast, are separate data that viewers can toggle on and off through their player settings.
- Open captions are created during video editing and become part of the final video file itself.
- Open captions work on any device and any platform because they are part of the video, not a separate feature the player has to support.
How open captions are created during video editing
Open captions are added to video using editing software. The creator opens the video file, adds a text layer with the words they want to display, positions it on the screen, times it to match the audio, and then exports the video with that text baked in. Common editing programs like Adobe Premiere Pro, Final Cut Pro, and DaVinci Resolve all have tools to add text layers and render them into the final video.
The process is similar to adding a watermark or a title card, except the text is timed to specific moments in the video. The editor sets the text to appear when a character speaks and disappear when they finish. Once the video is exported with the text included, that version becomes the master file — the captions cannot be removed without re-editing the video.
Because open captions are created during editing, they require planning. The creator has to decide what text to include, where to place it on screen so it does not block important visuals, what font and color to use, and how long each caption should stay visible. This is more work than adding closed captions after the fact, but it gives the creator full control over appearance and timing.
The difference between open captions and closed captions
Closed captions are stored separately from the video file itself. When you watch a video on YouTube, Netflix, or most streaming platforms, the captions are metadata — information attached to the video but not part of the image. The player reads this data and displays the text only if the viewer turns captions on. If the viewer turns them off, the text disappears.
Open captions have no off switch. They are part of the video image, the same way the actors and scenery are. A viewer cannot remove them through player settings because the player has no caption controls to toggle — the text is just pixels in the frame.
This difference matters for accessibility and user choice. Closed captions let viewers decide whether they want text on screen. Open captions force all viewers to see the text, which can be helpful for ensuring captions reach people who do not know how to turn them on, but it also means viewers who do not want captions cannot remove them.
When creators use open captions instead of closed captions
Some creators use open captions because the platform they are uploading to does not support closed captions well, or because they want to may provide captions appear on every device. A video shared on social media platforms that strip metadata might lose closed captions, but open captions will survive because they are part of the image.
Open captions are also used for creative reasons. A filmmaker might use open captions to show text messages appearing on a character's phone, or to display a character's internal thoughts. In these cases, the caption is not just accessibility — it is part of the storytelling. The text is meant to be seen by everyone and is often styled to match the scene.
Some creators use open captions for dialogue in foreign languages. Rather than relying on the viewer to turn on closed captions, the creator burns the translation directly into the video. This ensures the translation reaches viewers who might not know captions are available or how to enable them.
Open captions and accessibility
Open captions do help people who are deaf or hard of hearing see what is being said, but they are not the preferred accessibility solution. Closed captions are better for accessibility because they give viewers control — a person can turn them on if they need them and turn them off if they do not. Open captions force text on all viewers, which can clutter the screen for people who do not need them.
Closed captions also allow for more detailed information. They can include speaker labels, sound descriptions in brackets like [door slams] or [music playing], and notes about who is speaking off-screen. Open captions are usually just dialogue, because too much text makes the video hard to watch.
For true accessibility, creators should provide both: closed captions for viewers who want them and can control them, and open captions only when they serve a creative purpose or when the platform does not support closed captions.
Open captions on different platforms and devices
Because open captions are part of the video file, they appear the same on every device. A video with open captions looks identical on a phone, a computer, a tablet, or a TV. There is no setup required and no compatibility issues — the captions are just there.
Closed captions, by contrast, depend on the platform and the player. YouTube supports closed captions and makes them straightforward to toggle. Some older video players do not support them at all. A video uploaded to a platform that strips caption data will lose the captions unless they are open captions.
This reliability is one reason some creators choose open captions, especially if they are sharing videos across multiple platforms or if they cannot control which player the viewer will use.
Drawbacks of using open captions
Open captions take up space on the screen and can block important visuals. A caption at the bottom of the frame might cover a character's face or an important detail in the background. The creator has to carefully position the text to avoid this, which limits where captions can go.
Open captions also cannot be customized by the viewer. Someone who prefers larger text, a different color, or a different font has no way to change it. Closed captions let viewers adjust the size and appearance to suit their needs.
Creating open captions requires more work during editing. Closed captions can be added after the video is finished, or even generated automatically by the platform. Open captions have to be planned and timed during the editing process, which means more time in post-production.
Frequently Asked Questions
Can I turn off open captions if I do not want to see them?
No. Open captions are part of the video image and cannot be disabled through player controls. If you do not want to see them, you would need to watch a different version of the video without open captions, if one exists.
Are open captions the same as subtitles?
Not exactly. Subtitles usually translate dialogue from one language to another. Open captions include dialogue, sound effects, and speaker labels in the same language as the audio. Both can be open or closed, but they serve different purposes.
Do all video platforms support open captions?
Yes. Because open captions are part of the video file itself, they work on any platform and any player. There is no compatibility issue — the text appears wherever the video plays.
Why would a creator choose open captions over closed captions?
Creators use open captions when they want to may support captions appear on every device, when the platform does not support closed captions well, or when the text is part of the creative vision — like showing a text message on screen or translating dialogue.
Can I add open captions to a video after I have already exported it?
Not without re-editing. Open captions are baked into the video during export, so to add or change them, you would need to go back to the editing software, add the text, and export the video again.
