Use Cases
Why burn subtitles instead of soft subs?
Universal compatibility
Burned-in subtitles work everywhere - Instagram, WhatsApp, email, presentations. No player subtitle support required.
No viewer action needed
Viewers don't need to enable captions. Subtitles are always visible, increasing accessibility and engagement automatically.
Consistent styling across platforms
Your carefully designed caption styles stay intact. Soft subs get re-rendered differently by each platform's player.
Better for social media
Instagram, TikTok, and Twitter don't support soft subtitle files. Burned-in captions are the only way to add text to social video.
FAQ
Burn subtitles to video - FAQ
What does 'burn subtitles' mean?
Burning subtitles (hardcoding) means embedding caption text permanently into the video pixels. Unlike soft subs (SRT files), burned subtitles cannot be turned off - they're always visible.
Will burning subtitles reduce video quality?
No. CapsAI preserves original video resolution and bitrate. The only visual change is the addition of subtitle text rendered as a graphic overlay.
Can I burn an SRT file into a video?
Yes. Upload your video and SRT file together. CapsAI renders the SRT timing and text as permanent on-screen captions with your chosen styling.
Do I need FFmpeg or video editing software?
No. CapsAI handles everything in the browser and cloud. No command-line tools, no software downloads, no technical knowledge required.
Can I burn animated captions into video?
Yes. CapsAI supports word-by-word highlighting, bounce effects, and other animations that get permanently rendered into the video file.
