About Video Subtitle Burner - Hardcode Subtitles

Burn subtitles permanently into your video so they display on any player without needing a separate subtitle file. Upload an SRT or VTT subtitle file along with your video, customize the font, size, color, and position, then export a video with the text baked into every frame. This guarantees your subtitles show up correctly everywhere — social media, messaging apps, TVs, and any device.

Step by Step

  1. 1Upload your video file.
  2. 2Upload an SRT or VTT subtitle file.
  3. 3Customize font, size, color, background, and position.
  4. 4Preview the subtitles over the video to verify timing and appearance.
  5. 5Export the video with burned-in subtitles.

Feature Highlights

  • SRT and VTT subtitle format support
  • Customizable font, size, color, and outline
  • Adjustable subtitle position (top, center, bottom)
  • Background box with adjustable opacity
  • Preview with subtitle overlay before export
  • Timing verification against the video
  • Handles Unicode and special characters

Tips & Best Practices

  • Use a semi-transparent background box behind your text for maximum readability across different video content.
  • Keep subtitle lines short — two lines of 40 characters each is the standard for readability.
  • Test your subtitle timing by previewing the full video before exporting to catch any sync issues.

How It Works

There are two types of subtitles: soft subs (a separate text track that players render on top of the video) and hard subs (text permanently rendered into the video frames). Soft subs are flexible — viewers can toggle them on or off and sometimes change their appearance — but they require player support and don't work on all platforms. Hard subs are universal because the text becomes part of the image data. This tool handles the hard sub workflow: it parses your subtitle file, renders each line of text onto the corresponding video frames with your chosen styling, and re-encodes the result.

Popular Scenarios

  • Social media videos

    Burn subtitles into videos for Instagram, TikTok, and Facebook where many viewers watch without sound.

  • Accessibility

    Ensure deaf and hard-of-hearing viewers can always see captions, regardless of the player or platform.

  • Foreign language distribution

    Permanently embed translated subtitles into videos for distribution to audiences who don't speak the original language.

  • Archival copies

    Create definitive versions of videos with subtitles baked in, so the text is never lost or separated from the video file.

Frequently Asked Questions

Can I undo burned-in subtitles?

No. Once subtitles are burned into the video frames, they cannot be removed. Always keep a copy of the original video without subtitles.

Why do my subtitles look blurry?

If the video resolution is low, text may not render sharply. Try increasing font size or using a bolder font weight. A text outline or background box can also improve readability.

Can I burn multiple subtitle tracks (e.g., two languages)?

The tool burns one subtitle track at a time. To add a second language, burn the first, then use the output as input and burn the second at a different position.
