TL;DR
• Open captions stay on for everyone.
• Closed captions let viewers choose.
• Subtitles often focus on dialogue only.
• SDH and CC include extra sound info.
• Good styling improves readability fast.
Open Captions Vs Closed Captions
Both options show text for what’s said, yet they behave differently. So, your best choice depends on where the video plays.
Think “always on” versus “viewer controlled.”
• Open captions are permanently visible on-screen
• Closed captions can be turned on anytime
• On/off toggle gives viewers personal control
• Open captions work without player support
• Closed captions rely on a compatible player
• Open captions look identical for all viewers
• Closed captions can vary by device settings
• Open captions can’t be customized by viewers
• Closed captions may allow font size changes
• Open captions are great for public spaces
• Closed captions suit multilingual viewer choices
• Open captions can block visuals if misplaced
What Are Open Captions
Open captions are text baked into the picture. That means everyone sees them, even on mute.
Because they’re part of the video, they’re hard to avoid.
• Burned-in text is part of the image
• Always visible captions show for every viewer
• Hard-coded captions can’t be switched off
• Great for platforms with limited caption tools
• Useful when videos autoplay without sound
• Helpful for screens in gyms and cafés
• Consistent look across phones and TVs
• Easier for quick reposting across apps
• Can be styled to match branding safely
• May reduce flexibility for future edits
• Can cover faces if placed poorly
• Can’t be translated without re-editing
What Are Closed Captions
Closed captions appear as a separate caption layer. Viewers decide whether to enable them.
That flexibility helps different needs and environments.
• CC is viewer-controlled text display
• Caption track sits separate from the picture
• Viewers can turn on captions as needed
• Often includes dialogue and key sound info
• Can support multiple languages on many platforms
• May allow customization like size and color
• Easier to update without re-editing video
• Better for accessibility settings on devices
• Works well for long videos and series
• Depends on player and settings availability
• Can be missing if creators forget uploading
• Auto-captions may need careful corrections
Open Captions Vs Subtitles
Subtitles and captions are often mixed up. Still, they’re not always built for the same purpose.
Subtitles commonly focus on spoken words, especially for language support.
• Subtitles often show dialogue only
• Subtitles can support translation across languages
• Some apps offer dialogue-only subtitle tracks
• Open subtitles are burned into the picture
• Closed subtitles can be turned on like captions
• Subtitles may skip sound effects entirely
• Subtitles can help in noisy environments
• Subtitles are popular for late-night viewing
• Subtitles can reduce rewinding during fast scenes
• Subtitles don’t always label speakers clearly
• Open subtitles can’t be hidden by viewers
• Subtitles can vary by platform naming
Closed Captions Vs Subtitles
Closed captions usually aim to represent more than words. They can include important audio details too.
So, they’re designed for fuller access to the scene.
• Sound cues describe meaningful non-dialogue audio
• Speaker labels help identify who’s talking
• Non-speech info can include laughter or applause
• Subtitles often assume viewers can hear sounds
• Captions often support deaf and hard-of-hearing viewers
• Captions may note music changes or tone shifts
• Subtitles may be used mainly for translation
• Captions can include off-screen speech notes
• Captions can show phone ringing or door slams
• Subtitles may omit background audio completely
• Captions can be offered as separate language options
• Labels vary: CC, SDH, or captions
SDH Vs CC
SDH and CC can look similar, yet they may follow different style rules. The key is what’s included and how it’s presented.
In practice, both help viewers follow audio they can’t hear.
• SDH targets deaf and hard-of-hearing needs
• Includes music cues when they matter
• Adds sound effects like bangs or footsteps
• Often shows speaker changes more explicitly
• May include tone notes like “whispering”
• Can mark background voices clearly
• CC can also include sound information
• Naming differs by platform and region
• Some players group SDH under captions
• SDH lines may be more descriptive
• SDH is common on streaming services
• Pick SDH when audio context matters
Burned-In Captions Meaning
“Burned-in” is a common phrase for open captions. It simply means the text is part of the picture.
Once it’s there, it’s hard to remove cleanly.
• Baked-on text stays visible forever
• Embedded text can’t be separated later
• Permanent captions travel with the file
• Great for signage and public monitors
• Useful when players lack caption support
• Ensures everyone sees the same wording
• Limits edits if timing changes later
• Harder to localize into new languages
• Requires re-export for any corrections
• Can clash with on-screen lower-thirds
• Needs safe placement to avoid cropping
• Works best with clean, high-contrast styling
When To Use Open Captions
Open captions shine when you can’t rely on viewers enabling anything. That’s common on short-form platforms.
They also help when you want total control over placement.
• Perfect for silent autoplay viewing habits
• Helpful when platforms have caption limits

• Smart for short tutorials and recipes
• Helpful for brand videos on kiosks
• Risky if you need multiple languages
• Risky if visuals are already text-heavy
When To Use Closed Captions
Closed captions are ideal when your audience wants choice. Viewers can toggle them based on hearing, setting, or preference.
They’re also easier to update without re-editing footage.
• Best when viewer choice matters most
• Great for offering multiple language tracks
• Supports language options on many players
• Allows custom styling via device settings

Open Captions For Social Media
On social apps, many people watch without sound. That’s why open captions are often a safe bet.
If your content is quick, clarity wins fast.
• Built for the muted feed reality
• Great for short Reels with fast cuts

Closed Captions On Streaming And TV
At home, captions are often controlled by the device. That’s why closed captions dominate TV and streaming.
The player, remote, and menus decide the experience.
• Common across streaming apps libraries
• Found in TV settings under accessibility
• Often inside the accessibility menu section
• Useful for late-night watching with low volume
• Helpful when dialogue is hard to hear

• Can improve clarity on small TV speakers
• Sometimes varies between app and device menus
• Can be disabled per profile on some platforms
• Updates depend on app and device support
How To Turn On Closed Captions
The exact steps vary, yet the path is similar. Start playback, open options, then select captions or subtitles.
If you don’t see it, check accessibility settings too.
• Use the remote to open playback options
• Look for settings during a playing video
• Find the subtitles menu or CC icon
• Turn captions on, then choose a language
• Check device accessibility if icons are missing
• Look under “Audio & Subtitles” in many apps
• Try the pause screen if nothing appears
• Confirm captions stay on across episodes
• Restart the app if captions won’t stick
• Update the app if controls are outdated
• Check profile settings for subtitle preferences
• Test another app to isolate device issues
How To Add Captions To A Video
Creators can add captions as a separate file or burn them in. Your choice affects flexibility and edits later.
For most creators, starting with a separate track is easier.
• Upload captions as a separate caption file
• Export video, then attach captions on platforms
• Edit timing so lines match speech precisely
• Keep line length short for mobile screens
• Use consistent punctuation for readability
• Add speaker labels only when needed
• Include key sound notes for accessibility captions
• Avoid covering lower-thirds and product details
• Proofread names, numbers, and brand terms
• Test playback on phone and TV
• Save a master version for future updates
• Consider open captions for apps with weak support
Caption Accuracy And Quality
Quality captions feel invisible in a good way. When they’re wrong or late, everyone notices.
So, checking a few basics goes a long way.
• Accuracy matters for names and numbers
• Keep captions synced with the audio
• Ensure lines feel complete, not chopped
• Fix auto-caption mistakes before publishing
• Match punctuation to natural speech pauses
• Avoid censoring that changes meaning unexpectedly
• Include important background sounds when relevant
• Don’t paraphrase key instructions in tutorials
• Keep consistent capitalization across the video
• Remove filler words when they clutter meaning
• Check timing during fast dialogue scenes
• Verify captions don’t lag during playback
Caption Placement And Style
Even perfect words fail if viewers can’t read them. Good styling is about contrast, spacing, and safe placement.
A few small changes can boost readability fast.
• Use strong contrast against the background
• Stay inside the safe area for cropping
• Add clean line breaks at natural phrases
• Avoid placing text over busy patterns
• Keep two lines max for phone viewing
• Use larger text for distant TV viewing
• Avoid blocking mouths during interviews
• Leave room for app buttons and overlays
• Don’t cover product labels or key visuals
• Use a subtle background box when needed
• Match style across the whole video
• Preview on bright daylight screens too
Live Captions Vs Closed Captions
Live captions are created in real time. Closed captions are often prepared and edited before publishing.
Both help, yet they serve different moments.
• Live captions support real-time events
• Generated real-time during meetings or broadcasts
• Latency can cause slight delays in text
• Best for webinars, conferences, and live streams
• Prepared captions usually look cleaner and steadier
• Live captions can miss names and jargon
• Prepared captions allow careful proofreading
• Live captions help when audio drops or echoes
• Prepared captions handle fast dialogue better
• Live captions may need human support for accuracy
• Prepared captions can include richer sound notes
• Choose based on whether content is live
Dialogue-Only Subtitles Option
Some services now offer dialogue-only text options. These reduce extra sound notes for viewers who want cleaner screens.
Still, they’re different from accessibility-focused caption tracks.
• Dialogue-only shows just spoken words
• Creates clean subtitles with fewer labels
• Removes some audio cues like sound effects
• Useful for viewers who dislike extra descriptions
• Helpful when you only need speech clarity
• Not a replacement for full accessibility captions
• May reduce clutter in visually dense scenes
• Can suit casual viewing in quiet rooms
• Might confuse when off-screen sounds matter
• Works best for straightforward dialogue-heavy shows
• Options vary by title and language
• Check the language picker for new tracks
FAQs
What’s the difference between open captions and closed captions?
Open captions are always visible because they’re part of the video image. Closed captions are optional because viewers can turn them on or off in the player settings.
Can viewers turn off open captions?
No—open captions can’t be turned off because they’re baked into the picture. If you need an on/off option, use closed captions instead.
Are closed captions the same as subtitles?
Not always. Subtitles often focus on dialogue, while closed captions can include extra audio details like sound effects and speaker labels.
What does SDH mean, and how is it different from CC?
SDH stands for subtitles for the deaf and hard of hearing. It typically includes dialogue plus key audio cues, though labeling and formatting can vary by platform.
How do I turn on closed captions on streaming apps?
Start playing a show, open the playback menu, then select captions or subtitles. If you don’t see it, check the device’s accessibility settings.
Why do so many people watch with subtitles now?
Many viewers use subtitles for clarity in noisy rooms, quiet viewing, or hard-to-hear dialogue. It also helps when multitasking or catching fast speech.
