How to Add Open Captions to Your Video

If you want captions that are always visible, you need open captions. They are burned directly into the video, so viewers do not have to turn anything on.

That makes open captions especially useful for social video, short clips, product demos, and any video that needs to be understandable on mute.

What are open captions?

Open captions are subtitles or captions that are permanently embedded into the exported video file. Unlike closed captions, viewers cannot switch them off because they are part of the video itself.

That is the main tradeoff:

• Open captions are always visible and give you full control over style and placement.
• Closed captions can usually be turned on or off by the viewer and may be styled differently depending on the platform or player.

For social distribution, open captions are often the better choice because they travel with the video wherever you upload it.

When should you use open captions?

Open captions make the most sense when:

• the video will be watched on social feeds
• the viewer may be watching with sound off
• you want consistent caption styling across platforms
• you do not want to rely on each platform’s caption support or display settings

They are especially common on short-form videos for Shorts, Reels, LinkedIn, TikTok, and square feed videos.

What open captions help with

Open captions can improve:

• comprehension when viewers are muted or in noisy environments
• accessibility for many viewers, especially deaf or hard-of-hearing users
• retention on social videos where people decide quickly whether to keep watching
• consistency, because your caption design stays the same everywhere

One important nuance: open captions themselves are not the same thing as transcript SEO. Burned-in text is useful for the viewer, but it does not replace having a transcript, captions file, or surrounding indexable page copy.

How to add open captions to your video

The fastest workflow is:

1. Upload the video.
2. Generate or import the transcript.
3. Edit the wording and timing.
4. Style the captions for readability.
5. Export the final video with captions burned in.

That is the core workflow Recast now uses on its official subtitle pages: upload, generate and edit subtitles, then export captioned assets.

A practical caption workflow in Recast

1. Upload your source file

Start with the clip or full video you want to caption.

2. Generate captions automatically

Recast can generate subtitles from the audio, which gives you a first draft much faster than typing captions manually.

3. Review the text

Always check names, jargon, punctuation, and any places where the AI may have misheard the audio.

4. Adjust caption style

Focus on readability first:

• use a clear font
• keep enough contrast between text and background
• avoid placing captions too low where UI elements may cover them
• keep line length short enough for mobile viewing

5. Export the final captioned video

Once the captions look right, export the video with the captions burned in.

Open captions vs. closed captions

Choose open captions when:

• you want captions visible by default
• you care about brand styling
• you are publishing short-form videos across many social platforms

Choose closed captions when:

• you want users to control whether captions appear
• you need separate caption files for specific platforms or accessibility workflows
• you are publishing long-form video where platform-native caption support works well

Many teams use both: open captions for social clips, closed captions for long-form hosting platforms.

Common mistakes when adding open captions

Making captions too small

If the video is meant for mobile, tiny captions defeat the point.

Using long lines

Shorter caption lines are easier to read quickly.

Covering important on-screen elements

Keep captions clear of faces, lower-third graphics, product UI, and platform interface overlays.

Skipping the review pass

Auto captions save time, but they still need a human check.

Treating captions as only a styling feature

Captions are a readability and accessibility layer first. Design matters, but clarity matters more.

FAQ

What is the difference between open and closed captions?

Open captions are burned into the video and always visible. Closed captions are usually a separate track that the viewer can turn on or off.

Are open captions better for social media?

Often yes. They are more reliable for social distribution because the styling stays consistent and the viewer does not need to enable anything.

Do open captions help SEO?

Indirectly, they can improve watchability and engagement. But for search visibility, transcripts, caption files, and on-page text are still more useful than burned-in text alone.

Can Recast add open captions automatically?

Yes. Recast’s subtitle workflow is built around generating captions, editing them, and exporting a captioned asset you can publish.
