Caption terminology
Closed captions are separate from the video file. They can be toggled on/off by viewers. Common formats include SRT, VTT, and platform-specific formats.
Burned-in captions (also called open captions, hardcoded captions, or baked-in subtitles) are rendered permanently into the video frames. They cannot be disabled.
Both display text synchronized to speech. The difference is whether viewers can control visibility.
When to use closed captions
Long-form YouTube content. YouTube's caption system supports multiple languages, searchability, and viewer control. Uploading SRT files alongside video is best practice.
Accessibility compliance. Legal requirements (ADA, CVAA) typically specify closed captions because they can be styled by viewers with visual impairments.
Professional broadcast. Television standards require closed captions in specific formats (CEA-608/708).
Content where captions may distract. Visually complex content where some viewers prefer no text overlay.
Multi-language content. Separate caption tracks allow viewers to select their language.
When to use burned-in captions
Social media short-form. Instagram, TikTok, LinkedIn, Twitter all autoplay muted. Platform-generated captions exist but offer no styling control. Burned-in captions ensure your styling appears exactly as intended.
Styled caption animations. Highlight, karaoke, pop, bounce: animated caption effects require burning in. Separate caption files do not support animation.
Guaranteed visibility. Burned-in captions always display. No risk of viewer missing content because captions were off.
Platform consistency. The same video with burned captions appears identical everywhere. No platform-specific caption rendering differences.
Quick social sharing. When viewers share or download your video, captions remain attached.
Comparison
| Factor | Closed Captions | Burned-In |
|---|---|---|
| Viewer control | Yes | No |
| Styling options | Platform-dependent | Full control |
| Animation | No | Yes |
| Multi-language | Yes | One per video |
| File size | Smaller | Same |
| Accessibility compliance | Yes | Partial |
| Social media optimization | Poor | Excellent |
| YouTube SEO | Yes (searchable) | No |
Practical recommendations
YouTube videos: Both. Upload closed captions (SRT) for accessibility and SEO. Add burned-in captions if you want styled text visible in all playback contexts.
Instagram/TikTok/Reels/Shorts: Burned-in only. Platform captions exist but cannot be styled. Generate and style captions before uploading.
LinkedIn: Burned-in. The platform has caption support but it is inconsistent. Burned-in ensures visibility.
Website embeds: Closed captions if the player supports them. Burned-in as fallback for players without caption support.
Podcast clips: Burned-in. Short social clips need visible captions for muted scrolling.
Creating burned-in captions
The captions tool generates transcription and renders styled captions directly into exported video:
- Upload video
- Generate transcription (AI-powered, word-level timing)
- Style captions (font, color, animation)
- Export (captions are burned in)
The result is a video file with captions as part of the video frames.
Creating closed captions (SRT)
Most transcription tools export SRT files:
- Rev, Otter.ai, Descript for paid services
- YouTube's auto-generate for free option
- Manual creation in any text editor following SRT format
The SRT file uploads alongside or into your video on platforms that support it.
The hybrid approach
Many creators use both:
- Create video with burned-in captions for social platforms
- Export separate SRT for YouTube upload
- Maintain caption source file for future translations
The burned-in version is the primary deliverable. The SRT provides accessibility compliance and SEO benefits on YouTube.
Animation requires burning
If you want caption animations (highlight effects, word-by-word reveals, bounce, pop, glow), these must be burned in. Closed caption formats do not support animation.
Generate animated captions with eight animation styles, then export with captions rendered into video.
Accessibility notes
Burned-in captions do not fully satisfy accessibility requirements because:
- Viewers cannot adjust size, color, or font
- Screen readers cannot access the text
- Viewers cannot reposition captions
For content requiring strict accessibility compliance, provide closed captions. Burned-in captions can supplement but not replace closed captions for legal compliance.
